The Jeep Cherokee (XJ) is a unibody (monocoque) compact SUV. It shared the name of the original full-size SJ model, but without a body-on-frame chassis, it set the stage for the modern SUV. Its innovative appearance and sales popularity spawned important imitators as other automakers began to notice that this model began replacing regular cars.[3] It was built in Toledo, Ohio, in Beijing, China, in Ferreyra, Argentina and Valencia, Venezuela. The XJ provided the mechanical basis for the MJ-series Jeep Comanche pickup truck.

The XJ was selected by Robert Cumberford of Automobile magazine as one of the 20 greatest cars of all time, calling it "possibly the best SUV shape of all time, it is the paradigmatic model to which other designers have since aspired".[4]

1994–1997 Jeep Cherokee (XJ) Sport (Australia)
1993-1996 Jeep Cherokee XJ (Japan)

Designs of the XJ Cherokee date back to 1978 when a team of American Motors (AMC) and Renault engineers drew several sketches. A few clay models were based on the existing SJ Cherokee. Early sketches of the XJ Cherokee had a European influence, and most of the styling cues were done by AMC engineers under the direction of Richard A. Teague, Vice President of Design. This was a "masterpiece" design and paradigmatic model.[4]

Noticing that General Motors was developing a new two-door S-10-based Blazer, AMC decided to design an entirely new four-door model. AMC's Vice President of Engineering, Roy Lunn, designed what is known as the Quadra-Link suspension that limited rollovers.[5] Renault's François Castaing developed the drivetrain using a much smaller engine than normally found in 4WD vehicles and reduced the weight of the new model,[6]

The XJ Cherokee introduced for the 1984 model year was the first Jeep with a ladder-boxed chassis integrated into a single monocoque unit rather than the traditional separate body-on-frame construction. The design was rigid and sturdy, "yet wonderfully lightweight, [the] Uniframe permitted outstanding performance even with AMC's new 2.5-liter four-cylinder engine."[7]

Both two- and four-door versions of the XJ Cherokee were offered throughout its lifetime, each having exactly the same track and wheelbase measurements. Two-door models, however, received longer doors and front seats that could fold forward to assist in rear passenger entry and exit. This was in addition to extended-length rear windows that did not open, although an optional rear vent window was available on some models.

A variation on the Cherokee from 1984 through 1990 was the Jeep Wagoneer. These were unrelated to the similarly named full-sized Grand Wagoneer models that had carried the Wagoneer name before this point. The compact XJ Wagoneer was available in two trim levels: the "Wagoneer" and the "Wagoneer Limited". Both Wagoneers were distinguished from the Cherokee models by their two vertically arranged headlights on each side of the grille. The Wagoneer Limited came with vinyl wood trim on the sides and leather seats embossed with "Limited."

This version was the first to be sold in Europe; it was launched in 1992 in some markets, 1993 for the United Kingdom. Early versions had the 4.0 L (242 CID) six-cylinder engine only; the 2.5 L (150 CID) engine did not arrive in Europe until 1995.

In mid-1985, a two-wheel-drive version of the Cherokee was added to the lineup. This marked the first time any Jeep product was offered with two-wheel drive since 1967, and was done in the hopes of attracting a few more buyers who did not need (or want to pay for) four-wheel drive. When the XJ Cherokee-based Comanche (MJ) truck was introduced, it was also available in two- and four-wheel drive. The new two-wheel-drive models shared the front suspension with four-wheel-drive models. Jeep simply used a single axle tube from hub to hub with no differential between, resulting in a low added cost front suspension.

American Motors's compact XJ Cherokee was to be replaced by a new and larger model known as the ZJ (later named the Jeep Grand Cherokee when introduced in 1993) that was under development by AMC.[8] However, the smaller model's continuing popularity caused Chrysler executives to rethink this decision, and while the ZJ models were introduced in 1993, the XJ models were retained until 2001. The Jeep XJ has remained a popular choice by off-roading enthusiasts due to its potent off-roading capability in stock form. Its popularity has resulted in strong ongoing aftermarket support in the form of a wide variety of products and upgrade availability.

Government use

In the early- to mid-1990s, the Jeep Cherokee started becoming popular for government and police use. The Cherokee AHB police package was introduced during the 1992 model year. In response, for 1996, Jeep released a special version of the XJ Cherokee SE for police and fleet use. It featured no interior rear door handles and the 4.0L "Power-Tech" High-Output inline six-cylinder engine with 190 horsepower.

The Cherokee was also made in right hand drive format initially for the United States Postal Service, the side effect of this was it allowed Jeep in later years to enter right hand drive markets - the Cherokee went on sale in both the United Kingdom and Ireland in 1993.

After 13 years of production, 1997 saw the Cherokee receive updated exterior and interior styling. Both the two- and four-door bodies remained in production, receiving a steel liftgate (replacing the fiberglass one used previously),a new taillight design, additional plastic molding along the doors, as well as a new front header panel that featured more aerodynamic styling.

The interior was similarly updated with an all-new design and instruments, and a stiffer unibody frame brought improvements to Noise, Vibration, and Harshness (NVH) measurements. Also contributing to NVH improvements were new door seals that reduced wind noise at higher speeds.

In the middle of the 1999 model year, vehicles with the 4.0 liter (242 CID) engine received a much improved intake manifold. This was done to help counteract smaller exhaust porting on the latest casting of cylinder heads, which was done to meet more stringent emissions control laws. Both the four- and six-cylinder engines were offered through the 2000 model year, though only the straight-six was available in 2001. For the 2000 and 2001 model years, all six-cylinder XJs received a distributorless ignition system using coil-on-plug ignition replacing the 'traditional' system previously used; coupled with better exhaust porting and the newer intake manifolds, this gave a minor increase in power over the previous models. Transmission, axle, and transfer case choices were carried over from the previous models.

However, major changes were underway with a new executive, Wolfgang Bernhard, who was known as a "cost-slasher" nicknamed "whirlwind", came from Mercedes-Benz to turn around Chrysler.[9][10] "One of the first moves Bernhard made when he came to Chrysler in 2000 was to help kill the Jeep Cherokee, an aging, somewhat bland SUV."[11] Thus, the (XJ) Cherokee line was replaced in 2002 by the Jeep Liberty (KJ), although it is called the "Cherokee" in most foreign markets. The Cherokee (XJ) remains a popular vehicle among off-roading enthusiasts who modify such components as the suspension, drive train, and steering. When (XJ) Cherokee production ended in mid 2001, the portion of the Toledo South Assembly Plant devoted to its production was slowly torn down.[citation needed]

Government/Police Use

By 1997 the XJ Cherokee was still popular in police and government fleets nationwide. As expected, production of the Cherokee Special Service Package continued for the 1997 model year into the 2001 model year. It still had the same features as the 1996 Cherokee Special Service Package, but the engine now produced 195 horsepower, up 5 horsepower from 190. In 2001, when the XJ Cherokee ceased production and was replaced by the Jeep Liberty, the Cherokee Special Service Package was discontinued. The Jeep Liberty never featured a Special Service Package, however, police, and government agencies still used the Liberty in their fleets, and continue to this day.

Axles

The Jeep XJ utilizes front and rear solid (live) axles as opposed to independent front and/or rear axles. This configuration allows the XJ to have superior off-road capability and performance at the expense of some on-road comfort and driveability. Mid-1985 and later two-wheel drive models used the same basic suspension with a single tube connecting axle ends with no differential.

Front Axle

Rear Axle

Axle Gear Ratios

Jeep XJs came in several standard gearing ratios:

Suspension

The Jeep XJ utilizes a coil spring front suspension with a leaf spring rear suspension.

Front suspension

The Quadra-Link front suspension design locates the axle with four leading control arms to control longitudinal movement and rotation about the lateral axis (drive and braking reaction), two above the axle and two below it. A panhard rod, also referred to as a track bar, is used to locate the axle laterally. Two coil springs are seated on top of the axle housing as well as two gas-charged shock absorbers. The suspension used on vehicles with the optional UpCountry Package provided one inch of lift over the standard suspension. A sway bar is utilized to reduce body roll in turns.

Rear suspension

The XJ uses a leaf spring rear suspension. Each leaf pack contains four leaf springs with a fixed eye at the front of the spring and a compression-style shackle at the rear of the spring. Two gas-charged shock absorbers are also used, along with a mild anti-sway/anti-roll bar. The suspension used on vehicles with the optional UpCountry Package did not employ the rear anti-sway/anti-roll bar and provided one inch of lift over the standard suspension.

XJ in Europe

European passenger version Cherokee XJ

The XJ was introduced to left-hand drive European markets in 1985, one year after its American debut. However, right-hand drive European markets only began to officially receive them (in RHD form) in 1993. Models were offered in both markets until the XJ's discontinuation in 2001, at which point it was replaced by the KJ-model Jeep Liberty. The KJ Liberty, however, retained the Cherokee name for sale in Europe despite sharing little mechanical heritage with its predecessor.

A van version of the XJ was offered in addition to the standard passenger vehicles in some European markets. Available in both right- and left-hand-drive models, they were designed to comply with relaxed motor tax regulations in some EU member states governing vehicles intended for primarily commercial use. Both two- and four-door versions are known to have been sold, with the main differences from the standard models being metal panels in place of the rear side windows, no rear seats, and a completely flat cargo area. Two- and four-wheel-drive variants were available, powered by the VM Motori 2.5-litre diesel engine mated to the Aisin AX-5 manual transmission. Photographs of this model can be found here.[12]

XJ in China

China Model 2500 Jeep Cherokee (XJ platform)

American Motors established the first automobile manufacturing joint venture in the People's Republic of China to assemble the four-door Cherokee.[13] Production continued after Chrysler's buyout of AMC. Chrysler executives were concerned over licit and illicit technology transfers when knock-offs of the Cherokee began appearing in the Chinese market.[14] The Chinese market BJ 7250 and BJ 2021 (rear-wheel drive and four-wheel drive respectively) had a raised roof in the rear, as they were often meant to be chauffeur driven. Production under Mercedes-Benz continued in the partnership that was renamed Beijing-Benz DaimlerChrysler Automotive. The most recent model with an updated grille, headlights, and other upgrades was known as the "Jeep 2500"[15] and was produced until 2005.[16] It is notable that AMC's original Cherokee design continued to be built and sell after being virtually unchanged for over twenty years.

Possible Cherokee name revival in the U.S.

The automaker is considering renaming the next-generation Jeep Liberty the Jeep Cherokee in order to attract more buyers and prior Jeep owners to the brand. The Jeep Liberty is currently sold outside of North America as the Jeep Cherokee (KK).
