186-448: A GPS navigation system radio and Sirius Satellite Radio were offered for the first time. The Special Edition model was temporarily discontinued for the 2003 model year, but would reappear for 2004. 2003 was a shortened model year , with 2004 model year production commencing in mid-2003. During this year the WJ also received to minor changes during the model year, including the change from

279-440: A "4-speed automatic". In 2001, the programming was changed to make use of all six ratios. Rather than have six forward gears, the transmission was programmed to act as a five-speed with the alternate second gear for downshifts. The rpm at 70 miles per hour (113 km/h) on a 545RFE is 2000 rpm, 200 rpm less than the 45RFE programming. 1999 and 2000 model year WJ owners can have their 45RFE transmission's programming flashed to enable

372-721: A 2.72:1 reduction planetary gear set and the front and rear axles are locked together through the clutch pack. This same NV247 transfer case is the foundation for the Quadra-Drive system described below. In 2005 Jeep replaced the New Venture Gear NV247 transfer case with the NV245 transfer case. This transfer case actually has a center differential, allowing both the front and rear axles to have power supplied to them without driveline binding, even on dry pavement. The torque distribution under normal driving conditions (no tire slippage)

465-488: A 3.73 rear axle ratio. The New England Special Group was available exclusively in select Northeastern states. The Limited served as the top-of-the-line Grand Cherokee trim level from 1998 to 2001, and the more "luxurious" Grand Cherokee trim level from 2001 to 2004. It added these features: color-keyed body-side trim cladding panels and front and rear bumpers, a premium 180-watt Infinity Gold stereo system with 6 speakers, leather seating surfaces, dual power front bucket seats,

651-466: A button, or upon insertion of the corresponding key into the ignition (the keyless entry remotes were color-coded either black or gray, and had either a '1' or '2' on the back of the remote to help the drivers easily identify their remote). For the 2002 model year , the Grand Cherokee WJ received its first mid-cycle refresh. This included the introduction of three new models: a value-oriented Sport,

744-399: A center differential with a viscous coupler to provide smooth and efficient four-wheel drive operation on all surfaces. This system has 4WD All-Time, Neutral, and 4WD Low modes. In normal 4WD All-time mode, the center differential is open and distributes torque to both the front and rear axles. When a difference in speed occurs between the axles, heat buildup causes the viscous fluid inside

837-476: A complimentary Columbia parka (the Special Edition trim would also reappear for the 2004 model year ). The Laredo trim was condensed to a single "E" Package, though all previously available options were still available. All models received revised front fascias for 2004, and all four wheel drive models received Jeep 's new "Trail Rated 4X4" certification. This certification could typically be identified by

930-678: A deleted cassette player, and a deleted sunroof could be had for credit in place of the standard options they replaced. The Special Edition was a value-oriented trim level of the Grand Cherokee in 2002 and in 2004 (the model was put on hiatus for the 2003 model year). Based on the base Laredo trim, the Special Edition added these features: a full-sized spare tire/wheel, heated power dual front bucket seats, leather seating surfaces & leather-wrapped steering wheel, an A/M-F/M stereo with cassette, CD player, 10 disc rear mounted CD changer, color-keyed body-side cladding panels and front and rear bumpers,

1023-464: A differential with a cone-type slip-limiting clutch to distribute torque between the front and rear output shafts and 2) a vacuum-switch-operated differential lock. It offered only 4WD Hi modes in full-time (open) or part-time (locked) modes. The BW1339 added a 2.57:1 low range gearset to the BW1305, enabling 5 modes: 4WD Hi Locked, 4WD Hi Open, Neutral, 4WD Low Open, and 4WD Low Locked. The Jeep Quadra-Trac

1116-651: A full-color GPS navigation radio with a single-disc CD player and ten-disc remote CD changer became available on Limited and Overland models. All radios supported dealer-installed accessory Sirius Satellite Radio and U Connect hands-free Bluetooth phone system. To round out the changes for 2002, a full-size spare tire and wheel was now standard equipment on all models, front side-impact airbags and power-adjustable foot pedals were available (the Vehicle Identification Number differentiated between frontal airbags only and frontal and front side-impact airbags with

1209-534: A full-sized spare tire and spare wheel, a security alarm, a leather-wrapped steering wheel, steering wheel-mounted remote audio system controls, driver's 2-position memory (color-coded keyless entry remotes), wood interior trim, and more. The Sport was the lowest-priced trim level of the Grand Cherokee was introduced in November 2001, for MY2002. Offered only for 2002, the Sport was aimed at value-oriented customers who wanted

1302-452: A full-time four-wheel drive system that requires no driver input. This system under normal conditions sends all available torque to the front wheels while monitoring the speed of the front and rear axles. If the system detects that the front axle is moving more quickly than the rear axle then the system will send power through the power transfer unit to the rear axle until the speeds are the same. Applications: Active Drive II includes all of

1395-558: A functional oil pressure gauge to a "dummy" gauge (only showing if oil pressure is present or not), as well as changing from a hollow to a solid front sway bar starting on vehicles made after November 7, 2002, onwards. 2004 - 2004 would mark the Jeep Grand Cherokee WJ's final model year of production. There was a new Columbia Edition model that was introduced as a partnership between Jeep and Columbia Sportswear, and included unique seat trim, larger aluminum-alloy wheels, and

1488-432: A gerotor, a clutch pack coupled to a hydraulic pump, to transfer torque between the front and rear axles. The transfer case contains three modes, 4-All Time, Neutral, and 4-Lo. In 4-All Time, 100% of torque is sent to the rear axle in normal conditions. If the rear axle starts spinning at a higher rate than the front axle, hydraulic pressure builds up in the gerotor and causes the clutch pack to progressively transfer torque to

1581-490: A major refresh which introduced new features and models to the range, as well as minor changes related to cost cutting measures. To start, an all-new Jeep Grand Cherokee Overland model was introduced, as a new model positioned above the previously top Limited model, including features such as extended leather seating surfaces and door panels, an Infinity Gold premium amplified audio system, as well as genuine wood-trimmed interior and steering wheel. The Laredo trim now included

1674-539: A mechanical differential lock to 4WD Low mode, making it much more durable for serious off-road use. The NV249-based Quadra-Trac system was replaced by the NV247-based Quadra-Trac II system for the 1999 to 2004 Jeep Grand Cherokee (WJ). Applications: Quadra-Trac II was introduced in 1999 and it employs a two-speed chain-driven transfer case featuring three modes of operation, "4-All Time", "N" or neutral, and "4-Lo". Two different transfer cases were used,

1767-587: A modified version known as NP-231J HD which was supposedly (SP) a "heavy duty" version for the Jeep Grand Cherokee (ZJ) with V8 engines. The NP/NV-231 case is a chain-driven unit that takes 21- or 23-spline input shafts. The 23-spline was for the AX-15 transmission, and the 21-spline was used for the AX-5 and BA 10/5 transmissions. Low range for this case was 2.72 and high range was 1.00. The Command-Trac HD transfer case

1860-471: A premium 180-watt Infinity Gold audio system with 6 speakers, Bright Silver Metallic-painted body-side cladding panels and front and rear bumpers, and 'Columbia Edition' emblems on both front doors. Columbia Edition buyers also received a complimentary Columbia parka at the time of delivery of their new vehicle. The Overland was the top-of-the-line Grand Cherokee trim level between August 2001 and 2004, first introduced for MY2002. It added these features to

1953-587: A premium 180-watt Infinity Gold audio system with 6 speakers, and 'Freedom' emblems on both front doors. The Columbia Edition , launched in November 2003 (2003/10/06 SOP) was a partnership between Jeep and sportswear manufacturer Columbia for MY2004. Based on the base Laredo trim, the Columbia Edition added these features: a full-sized spare tire and spare wheel, seventeen-inch (17") alloy wheels, unique two-toned cloth seating surfaces, dual power front bucket seats, an A/M-F/M stereo with cassette and CD players,

2046-586: A reinforced case but the 2.72 low range. The Jeep Grand Cherokee/Commander line no longer offers a part-time transfer case option. The reason behind this was its poor sales along with an improved Selec-Trac. Selec-Trac and a simplistic Quadra-Trac had the convenience and comfort of "Full-Time" all wheel drive that Command-Trac lacked for "luxury" SUV's that did not require the more rugged part-time system. The terms "Command-Trac" and "Selec-Trac" were used in other Jeep lines and refer to different transfer cases in those lines. Applications: Command-Trac II works

2139-712: A secondary minor facelift for 2004 including round fog lamps, a lower front fascia and a new body-color matched inset grille design. Export models produced at the plant in Graz, Austria, were given the vehicle designation of "WG", which feature minor differences from the US model, including a relocated radio antenna (moved from front right fender to integrated on rear passenger side window), power folding mirrors, height adjustable headlights, plastic rocker covers on Limited trim models (only available on Laredo trim on US models), as well as leather shift knobs on Overland trim models. Chrysler also claims

2232-554: A security alarm, power sunroof, 180-watt Infinity Gold audio system and 'Special Edition' emblems on both front doors. The Freedom was a value-oriented trim level of the Grand Cherokee between March 2003 (SOP 2003/03/10) and 2004. Based on the base Laredo trim, the Freedom added these features: a full-sized spare tire and spare wheel, seventeen-inch (17") graphite-finish alloy wheels, unique cloth seating surfaces, dual power front bucket seats, an A/M-F/M stereo with cassette and CD players,

2325-597: A shift lever on the console. The NP228 differs from the NP229 by not having the viscous coupling in 4WD Hi mode, reverting to a simpler open center differential. Both transfer cases still lock the center differential in 4WD Lo mode. The NP228/229 transfer cases were available in the full-size Jeeps from 1983 to 1991. The NP228 was also available in the XJ Cherokee and Wagoneers and the MJ Comanche pickups from 1984 until replaced by

2418-483: A six-way, power-adjustable front driver's seat and an A/M-F/M stereo radio with a single-disc CD player a standard equipment, as well as revised seat fabrics, and new "Silverblade" aluminum-alloy wheels. Midyear, a new Special Edition model was introduced based on the Laredo model that added color-keyed front and rear bumpers and body side cladding, an Infinity Gold 180-watt premium amplified audio system, and unique badging on

2511-487: A split-folding 60/40 rear bench seat, gray-painted front and rear bumpers and body-side cladding trim panels, and more. After MY1999, the Laredo 26D Package was dropped, leaving the Laredo 26E/28E Packages as the base Grand Cherokee packages, and adding a standard overhead Electronic Vehicle Information Center (EVIC/VIC) and overhead console. Many features that were available on the luxurious Limited trim could also be optioned on

2604-456: A very well-equipped vehicle at a modest price point. It added these features to the base Laredo trim: dual power front heated bucket seats, leather seating surfaces, an A/M-F/M stereo with cassette and CD players, a premium 180-watt Infinity Gold audio system with 6 speakers, a full-sized spare tire and spare wheel, a 'sport' emblem on the tailgate, a security alarm, a power sunroof, and more. Cloth seating surfaces, deleted heated front bucket seats,

2697-478: Is 48% front and 52% rear. There is also an electronically controlled variable lockup clutch pack that can apply progressive 0 to 100% locking across the center differential. This is the improvement over the Selec-Trac NV242 transfer case, as that system has only fully unlocked and fully locked settings and requires manual shifting between them. And finally, the NV245 has the 'N' and '4WD Low' modes which act in

2790-491: Is a center differential that is open in 4WD Hi Full-Time mode and distributes torque 48/52% front-to-rear. This mode can be used on dry pavement or slippery surfaces with only a small fuel mileage penalty compared to 2WD mode. In 4WD Hi Part-Time and 4WD Low, the center differential is mechanically locked, so these modes are for slippery surfaces only. Low range engages a 2.72:1 planetary gear ratio for increased torque and low speeds. Overall, this system functions very much like

2883-488: Is an unusual construction scheme, it incorporates all of the strength and durability of a body-on-frame construction into a unitized construction. By adding stiffness and rigidity to the structure, they enhanced the ride and strengthened the network of steel beams, rails and pillars (or "safety cage") that surround and protect occupants. More than 70 percent of the underbody is high-strength steel. All Jeep Grand Cherokees feature UniFrame construction. The Grand Cherokee received

2976-445: Is available with either a CVT gearbox or most commonly with a 6-speed manual gearbox and has two settings on the traction control and electronic stability program systems to cater for off-road activity, U.S. FDII suspension travel and a full-size spare tire. Skid plates and tow hooks are options in the EU, but the hill descent control system is not available. Applications: Active Drive I is

3069-535: Is based on the Quadra-Trac II system but adds gerotor differentials to the front and rear axles to create a four-wheel drive system capable of not only directing torque to the axle with the better traction but to the individual wheel on an axle with better traction. Quadra-Drive uses the New Venture Gear NV247 transfer case mated to front and rear axles containing Jeep's Vari-Lok which are gerotor -equipped differentials . Applications: Quadra-Drive II uses

3162-550: Is different from Wikidata All article disambiguation pages All disambiguation pages Jeep Grand Cherokee (WJ) The Jeep Grand Cherokee (WJ) is the second generation of the Jeep Grand Cherokee sport utility vehicle . Unveiled in Detroit, Michigan , on June 16, 1998, production lasted until 2004 in the US, continuing in foreign markets until 2005. The WJ was completely overhauled from its ZJ predecessor, and

3255-551: Is unlike the XJ Cherokee that was significantly modified by Beijing Jeep for the Chinese market. The 3.1 liter turbo-diesel on the 1999 Grand Cherokee was developed in conjunction with Detroit Diesel / VM Motori . It has an electronic injection pump, electronically controlled, vacuum-actuated exhaust gas recirculation , and a special catalyst to control oxides of nitrogen (NOx). Manufactured in Cento , Italy, at 13,000 units per year. It

3348-677: The Jeep Cherokee (XJ) in 1984. The system offers a chain-driven, aluminum, "shift-on-the-fly" transfer case. The "shift-on-the-fly" feature provides manual ease and assist while engaging 4WD. Command-Trac should only be driven in 4WD on low-traction surfaces due to the front and rear axles being locked together (no differential action in the transfer case). Driving in 4WD on dry pavement causes excessive tire and drivetrain wear. Four-wheel modes are most commonly used for wet/slick surfaces or extreme weather conditions (rain, snow, etc.) (4H), towing (N), and off-road activities (4L). There are reports of

3441-634: The Compass and Patriot . There are two versions of the basic Freedom Drive system for the US Market, called I and II. Freedom Drive I is a light duty full-time electronically controlled all wheel drive system with a locking mode to set the front/rear torque split for especially slippery conditions in the Jeeps derived from the Chrysler/Mitsubishi GS Platform. Applications: Freedom Drive II uses

3534-475: The New Venture Gear NV245 transfer case mated to front and rear axles containing electronic limited slip differentials or ELSDs. Jeep added traction control in 2005 and starting in 2011 only a rear ELSD is offered, while the front has an open differential. Applications: Freedom Drive is Jeep 's four wheel drive system used in its compact crossover SUVs based on a front wheel drive platform,

3627-461: The Grand Cherokee received new aluminum-alloy wheel options, and the Limited trim received new leather seating surfaces and revised burl rosewood interior trim (the Laredo model received simulated brushed aluminum interior trim, and now included a trim bezel around the radio). The steering wheel on all models also received a silver-finished 'Jeep' emblem. 2002 - For 2002 the Grand Cherokee WJ received

3720-413: The Laredo trim, while the Sport model was discontinued. The Laredo model now included high-back front bucket seats with integrated headrests as standard equipment, with low-back front bucket seats with separate headrests becoming an option (the low-back bucket seats were standard when the Laredo trim was ordered with the optional "Royale" leather-trimmed seating surfaces). New entertainment options, including

3813-598: The Laredo-based Special Edition, and the new range-topping Overland. A new 4.7L High-Output Power Tech V8 gasoline engine became available on Limited models, and was standard on Overland. All models receive new radios, which included a standard A/M-F/M stereo radio with a single-disc CD player on Laredo and Limited, with an A/M-F/M stereo radio with Radio Data System (RDS) and cassette and single-disc CD players standard on Overland and optional on all other models (both radios featured standard CD changer controls for

3906-631: The MP3022 transfer case. Applications: The Quadra-Trac name is used on a variety of full-time 4WD systems. The first version used the Borg-Warner BW1339 transfer case and was produced from 1973 to 1979. The next version used the New Process NP219 transfer case and was produced from 1980 to 1982. From 1993 to 1995 the New Process NP249 transfer case carried the name. And from 1996 to 1998

3999-561: The NP129 model transfer case. The NP129 contained a viscous coupling around an open differential for added traction in slippery conditions. The NP128 has also been found equipped in select model years, which does not feature a viscous coupling. The NP242 Selec-Trac transfer case debuted alongside the Fuel-Injected 4.0L Inline-6 in the compact Jeep Cherokee in 1987. The shifter has modes 2WD - 4WD Hi Part-Time - 4WD Hi Full-Time - N - 4WD Low. There

4092-509: The NP228 transfer case above, just with all of the mode and range controls via a single, console-mounted shift lever. It was available in the 1987 to 2001 XJ Cherokee and Wagoneer, the 1987 to 1992 MJ Comanche, the 1993 to 2004 ZJ and WJ Grand Cherokees, the 2002 to 2007 KJ Liberty, and the 1998 to 2000 Dodge Durango. It was replaced in the 2005 Grand Cherokee by the Quadra-Trac II system featuring

4185-535: The NP242 in 1987. Several companies have offered a dual shift lever conversion which replaces the vacuum switch and solenoid with a more reliable second console lever for 2WD-4WD mode selection. The AMC Eagle used the NP119 transfer case in 1980, a strictly full-time all wheel drive model. From 1981 to 1988, a similar system was employed, dubbed "Select-Drive", which allowed the vehicle to switch from all wheel drive to 2WD using

4278-500: The NV245 transfer case with 4WD Auto mode and in the 2008 KK Liberty by Selec-Trac II using the MP3022 transfer case. Applications: Selec-Trac II uses a console mounted switch to control the MP3022 transfer case. The switch controls the 4WD mode with options of 2WD - 4WD Auto - N - 4WD Low. The MP3022 transfer case uses an electronically controlled clutch pack to bias torque from 100% rear to 50/50% front/rear. The transfer case has no center differential, so power can only be supplied to

4371-476: The NV247 in 1999-2004 WJs and the NV245 in 2005-2010 WKs and 2006-2009 XKs. For the 1999-2004 Jeep Grand Cherokees using the NV247 transfer case, in "4-All Time" mode torque is applied to only the rear wheels under normal driving conditions. A gerotor pump is connected between the front and rear output shafts and senses any speed difference between them. When the shafts are turning at different speeds (wheel slippage),

4464-496: The WJ Grand Cherokee featured a more modern exterior design, and an all-new interior. While the 4.0L "Power-Tech" Inline Six-Cylinder (I6) engine and 42RE four-speed automatic transmission both carried over from the previous-generation model, the previous 5.2L "Magnum" V8 engine was replaced by an all-new 4.7L "Power-Tech" V8 engine, which was mated to the all-new 45RFE four-speed automatic transmission (the 5.9L "Magnum" V8 engine

4557-439: The WJ was notable. It included three planetary gear sets rather than the two normally used in a four-speed automatic. This gave it six theoretical speeds, and it would have been the first six-speed transmission ever produced in volume, but it was programmed to only use five of these ratios. Four were used for upshifts, with a different second gear for downshifts. Although five of the six ratios were used, Chrysler decided to call it

4650-609: The XJ classic Cherokee from 1984 to 2005. Beijing Jeep bought the old tooling for the WJ Grand Cherokee when the WK was introduced for the U.S. as a 2005 model. The WJ was introduced in the end of 2004 for the Chinese market as the Jeep 4000 and 4700 Grand Cherokee and carries differing engine names compared to their foreign counterparts known as C698QA1 for the 6 cylinder and C8V93Q for the V8. A 4 speed automatic gearbox

4836-710: The axles, thus enabling flat-towing the Jeep behind another vehicle. In 1983, the NP219-based Quadra-Trac system was replaced by the NP228/229-based Selec-Trac , adding a fuel-saving 2WD mode to the full- and part-time 4WD modes of Quadra-Trac. Applications: In 1993 Jeep re-introduced Quadra-Trac, this time on the Jeep Grand Cherokee using the NP249 transfer case. Like the NP219, this transfer case utilizes

4929-541: The badge placed on the front driver's side fender, however many Grand Cherokees did not receive the badge, despite being certified as “Trail Rated.” Production concluded in April 2004, with the all-new Jeep Grand Cherokee (WK) being introduced in the same month at the New York International Auto Show . The Laredo served as the base Grand Cherokee trim level from August 1998 to 2004, and still continues to be

5022-494: The base Grand Cherokee trim level to this day. A very well-equipped model, the Laredo offered these features as standard equipment: the 4.0L Power-Tech Inline Six-Cylinder (I6) engine, a 4-speed automatic transmission, sixteen-inch (16") alloy wheels, an A/M-F/M stereo with cassette and CD player (1998-2001) or CD players (2001-2004), wood interior trim (1998-2000) or aluminum interior trim (2000-2004), keyless entry, power windows and door locks, cloth seating surfaces, air conditioning,

5115-422: The base Laredo added seventeen-inch tires and "Silverblade" aluminum-alloy wheels, a combination A/M-F/M stereo radio with cassette and CD players, and a power-adjustable front driver's seat to the base model. Another new package for the Laredo included the same feature content, but also added "Royale" leather-trimmed seating surfaces and an Infinity Gold premium audio system with a 180-watt amplifier. All models of

5208-496: The base Laredo trim. For 2001 only, a New England Special Group was available for Grand Cherokees equipped with the 26E Package. The package, which was indicated by the sales code ACJ, added features to the base model Grand Cherokee such as P235/65R17 BSW all-season performance tires, seventeen-inch (17") sport alloy wheels (both options of which were also available with the 26S and 28S Packages), an A/M-F/M stereo with cassette and CD players with integrated remote CD changer controls, and

5301-425: The cargo compartment to under the floor. The two heavy pushrod V8 engines were replaced by Chrysler's then-new PowerTech . The new V8 engine produced less torque than the old pushrods, but was lighter, offered better fuel economy, and provided similar on road performance figures (the 23-gallon fuel tank was replaced with one of a 20.5-gallon capacity). The Inline 6 engine was also updated for MY1999. A redesign of

5394-444: The characters '4' and '8' respectively as the third digit) and center roof rack cross rails were now only available as a dealer-installed accessory for all models. A second exterior facelift was introduced for the 2004 model year , and included revised front grilles and fascias (bumpers) for all models (Laredo models also received newly styled round front fog lamps as an optional feature). The Laredo-based Special Edition model rejoined

5487-409: The climate control panel to monitor the surface temperature of both driver and front passenger to automatically control the interior temperature for both front passengers. The Jeep Memory System allowed for two drivers to set their individual driver's seat, side mirror, and radio setting by using buttons located on the front driver's door interior panel to recall their preferred settings at the touch of

5580-412: The clutch pack bleeds off slowly, which progressively unlocks the clutch pack and biases torque output towards "rear only" unless the rear wheels are still slipping. There is no center differential, so on dry pavement the front and rear output shafts cannot be locked without causing driveline binding. The "N" or neutral mode is intended for towing the vehicle. In "4-Lo" mode, the input shaft drives through

5673-477: The coupler to thicken, which progressively locks the center differential thus transferring power to the axle with more traction. In 4WD Low, the input torque is multiplied through a 2.72:1 planetary gearset. NP249 transfer cases used the viscous coupler to transfer power in both high and low ranges. Applications: In 1996 the NP249 was replaced with the New Venture Gear NV249 transfer case. This added

5766-533: The extra gear as both transmissions are physically the same. The 42RE 4-speed automatic remained the transmission for the Inline 6 engine. It had slight changes from the previous model Grand Cherokee. The interior was also completely redesigned. The redesign allowed for larger rear doors, and more space for rear passengers. Controls for various items like headlights, heated seats, and rear wiper were moved to more convenient locations. The electronic Vehicle Information Center

5859-403: The following modes: 4H LK, 4H, N, and 4L. In 4H (full-time 4WD High) a center differential with a viscous limited-slip coupling is used between the front and rear output shafts. A 2.61:1 low range was engaged in 4WD Lo mode. And in both '4H LK' (4WD Hi Locked) and '4L' modes the center differential is mechanically locked. The 'N' mode disengages the transfer case, transmission, and engine from

5952-440: The front axle until both axles return to the same speed. Neutral mode is intended for towing the vehicle. In 4-Lo, the front and rear axles are locked together through a 2.72 reduction gear ratio. The NV247 transfer case is mated to front and rear axles containing Jeep's Vari-Lok differentials. Vari-Lok differentials also use a gerotor to transfer torque between the wheels on either side of the axle. The major advantage of Quadra-Drive

6045-506: The front axle when the rear wheels begin to slip. In this way, the transfer case works almost identically to the NV247 transfer case used in the Quadra-Trac II system in 1999 to 2004 WJ Jeep Grand Cherokees. In 4WD Low mode, the clutch pack is locked and power flows through a 2.72:1 planetary gear set for higher torque at lower speeds. The 2018 and newer JL Wrangler comes by default with Command-Trac, but its Sahara trim can be upgraded to Selec-Trac II, marketed as simply Selec-Trac, utilizing

6138-470: The front doors of the vehicle. A new "High Output" 4.7L "Power-Tech" V8 engine became available, standard on Overland, and optional on Limited.

6231-582: The intake manifold added 10 horsepower (7.5 kW). While other Jeep vehicles used the Mopar 5 x 4.5 bolt circle, this was the first Jeep following the 1987 Chrysler buyout to receive a wider wheel bolt pattern: – 5 x 5 - (metric 5 x 127mm). A notable feature available in this generation was the automatic four wheel drive option called Quadra-Drive , which employed the New Venture Gear NV247 transfer case. This two-speed chain-driven transfer case uses

6324-455: The lineup, and a new Columbia Edition model (also based on the Laredo) was introduced. The base Laredo model was now only available with the base "E" Package, and included fewer standard features (including the deletion of carpeted front and rear floor mat and rear cargo area tonneau cover). Production of the Grand Cherokee WJ ended in mid-2004, as the all-new third-generation Jeep Grand Cherokee (WK)

6417-434: The luxurious Limited trim level: unique seventeen-inch (17") "Rogue" chrome-plated alloy wheels, '60th Anniversary Edition' emblems on both upper front fenders, heated front bucket seats, a power sunroof, an A/M-F/M stereo with cassette and CD players, a matching spare wheel, '60th Anniversary Edition'-embroidered front bucket seats, along with special 60th Anniversary Edition floor mats. Beijing Jeep Corporation, Ltd. produced

6510-983: The optional ten-disc remote CD changer in the rear cargo area). For vehicles equipped with the Infinity Gold premium audio system, the 'Infinity Gold' emblem was removed from the front door speaker grilles, and the Laredo no longer featured carpeted front and rear door panels.

A new front grille and headlamps were introduced on Limited models, new tire and wheel combinations were available for all models, and in midyear 2002,

6603-426: The pump supplies oil under pressure to a wet clutch pack. The clutch pack applies progressive 0 to 100% locking between the front and rear output shafts. For example, if the rear axle starts rotating at a significantly higher rate than the front axle, the gerotor pump causes the clutch pack to progressively lock, transferring torque to the front axle until both axles are driven at the same speed. The apply pressure in

6696-570: The same as Command-Trac but uses a console mounted switch to control the MP1522 transfer case as opposed to a floor mounted lever. Applications: Rock-Trac is similar to Command-Trac but uses the New Venture Gear NV241OR and adds locking differentials and 4:1 low gear ratio. In 2007 an electric front sway bar disconnect was added and the locking differentials switched from air-actuation to electric actuation. Applications: Selec-Trac

6789-594: The same hardware as the FDI system but adds a lower axle gear ratio in conjunction with the CVT to simulate the benefits of a low-range transfer case, giving a 19:1 overall gear ratio for off-road use. This function is an alternate program in the CVT and is not a transfer case function. FDII also adds a hill descent control system , off-road tuned traction control , and electronic stability program . The Patriot with FDII also features longer suspension travel (all 4x4, post 2011 models have

6882-685: The same manner as in the NV247 transfer case above. The major difference between the NV245-based Quadra-Trac II and Quadra-Drive II is that Quadra-Trac II uses the Brake Traction Control System (BTCS) instead of electronically controlled differentials. When it senses a left-to-right speed differences between wheel hubs BTCS can apply each of the vehicle's brakes independently, similar to anti-lock brakes , enabling Quadra-Trac II's open front and rear differentials to offer limited-slip capabilities. Applications: Quadra-Trac I

6975-565: The same suspension), skid plates, tow hooks, and a full-size spare tire. This enables the FDII-equipped Patriot to wear the "Trail Rated" badge from Jeep.

A state-of-the-art automatic dual-zone climate control system used infrared sensors located in

7161-683: The transfer case was manufactured by New Venture Gear with some minor improvements and it was renamed the NV249. Quadra-Trac was the trade name for the Borg-Warner 1305 and 1339 gear cases. It was a chain-drive system introduced in 1973 on the full-sized Jeep line behind the AMC version of the Turbo-Hydramatic 400 automatic transmission. CJ7s also received the Quadra-Trac starting in 1976. The BW1305 included 1)

7254-471: The vehicle is being operated. Jeep Grand Cherokee vehicles manufactured February 13, 2001, through May 23, 2003. Quadra-Trac II Jeep uses a variety of four-wheel drive systems on their vehicles . These range from basic part-time systems that require the driver to move a control lever to send power to four wheels, to permanent four-wheel systems that monitor and sense traction needs at all four wheels automatically under all conditions. Command-Trac

7347-588: The vehicle received other improvements to reduce "NVH". "WG" models were also manufactured at the Cordoba plant for the Argentinian market. The first-generation Jeep Grand Cherokee (ZJ) offered many new and class-exclusive features, and the second-generation Jeep Grand Cherokee WJ continued to offer new features that were not yet available on its competitors, such as the Chevrolet Blazer and Ford Explorer . At

7440-532: Was available in European models and meets the European stage III emissions.

The 60th Anniversary Edition was manufactured to commemorate Jeep 's 60th anniversary in 2001. It added these features to

7626-446: Was differentiated from the open "New Process" Gear NP203 used by Dodge , General Motors , and Ford in that it included a center limited slip differential feature, in this case a clutch pack. Applications: The Borg-Warner system was replaced with a "New Process Gear" NP219-based system in 1980 The NP219 Quadra-Trac transfer case was available in full-size Jeep Cherokee, Wagoneer, and Grand Wagoneer from 1980 through 1982. It offered

7719-457: Was dropped after the 1998 model year ). The spare tire and wheel were relocated from the left side of the rear cargo area to underneath the cargo floor.

7812-531: Was first introduced in the full-size Jeeps (SJ) in 1983 using the New Process NP228 and NP229 transfer cases. These are very similar to the Quadra-Trac NP219 transfer case described in the next section below. The differences are 1) they added a 2WD mode for fuel savings and 2) the 2WD-to-4WD modes were controlled via a vacuum switch on the dashboard. The Hi-N-Lo range selection was still performed using

7905-571: Was first introduced using the NP208 transfer case in the full-size Jeeps (SJ series) in 1980. The drive modes are the same as with the Dana 18 and 20 transfer cases: 2Hi, 4HI PT, and 4LO PT. The 4WD modes are not for use on high-traction surfaces such as dry roads. The NP208 was used through at least 1987. More commonly, Command-Trac is used to refer to the NP/NV-231 or NP-207 transfer cases introduced along with

7998-526: Was introduced in 2004 and works similarly to the Quadra-Trac II system, but eliminates the "4 Lo" and "N" or neutral modes. By excluding these modes it creates a system that requires no driver input. In 2005 Jeep added the brake traction control system and replaced the New Venture Gear NV147 transfer case with the NV140 transfer case. Applications: The Quadra-Drive system was introduced in 1999 and

8091-513: Was introduced, and the Jefferson North Assembly Plant received a retooling for production of the all-new model. All 2004 models equipped with four wheel drive received Jeep 's "Trail Rated 4X4" certification, and an emblem on the front left fender. 1999 - 1999 saw the introduction of the all-new, second-generation Jeep Grand Cherokee WJ. While similar in dimensions and style to the first-generation Jeep Grand Cherokee (ZJ) ,

A CD-changer with capacity for 10 CD's was also available with the Infinity Audio package. In addition to Jeep's UniFrame construction, Daimler Chrysler partnered with Porsche to further strengthen the frame. This was done to reduce noise, vibration, and harshness (NVH). UniFrame

8277-450: Was renowned for its off-road capability. Jeep marketed the (WJ) as "the most capable SUV ever." Unveiled at Detroit, MI Cobo Hall on June 16, 1998, the redesigned WJ 1999 Grand Cherokee shared just 127 parts with its predecessor (mostly fasteners) and took 28 months to develop from its March 1996 design freeze (styling approval in Q3 1995). The spare tire was relocated from the side of

8370-570: Was replaced by the 545RFE five-speed automatic transmission. Finally, the base Laredo "D" Package was discontinued, which meant that the Laredo model now included the Electronic Vehicle Information Center (EVIC) with an overhead console as standard equipment. 2001 - For 2001, a 60th Anniversary Edition Jeep Grand Cherokee , based on the Limited model, celebrated the Brand's sixtieth anniversary.
