A T-18/T-18a four speed manual gearbox was standard for all years, while through 1979 the General Motors’ Turbo-Hydramatic TH400, more commonly fitted to 3/4- and 1-ton trucks rather than SUVs, was optional. For comparison, the Chevy Blazer used the TH350 automatic. After 1979, the TH400 was replaced by the Chrysler’s TorqueFlite 727.
A gear-driven Dana 20 transfer case with 2.03:1 low range was standard with the manual gearbox (which had a much lower first gear of about 6.3:1), while the TH400 automatics received the permanent four-wheel drive QuadraTrac system. The chain-driven, aluminum QuadraTrac was quite advanced at the time. It included a vacuum operated center differential lock. The transfer case was offset, allowing it to sit just above the frame to avoid obstacles, and the chain itself is larger than nearly any other. A test by the Four-Wheel Drive Book found that the Cherokee was the only vehicle unable to be dynoed because the transfer case would not allow the rear wheels to spin, unlike the other full-time four-wheel drive vehicles being tested. In the off-road test, the same held true. This transfer case was also employed successfully in Baja races, for example by Roger Mears in the Baja 1000. A 2.57:1 low range was optional on QuadraTrac.
In 1975, the Cherokee Chief package was introduced. Aside from trim changes, this model received larger fenders and wider axles, allowing larger tires to be fitted to further improve off-road ability. Four-door models were not available with «wide-track» axles.
Dana 44 model axles were used both in the front and the rear at least through 1979. Brake hardware was mostly General Motors equipment, with disc brakes up front (optional on earlier models) and drum brakes in the rear.
All Cherokees had semi-elliptical leaf springs in the front and rear.
The Cherokee was a redesigned reintroduction of a two door body style, with a single fixed rear side window with an optional flip-out section. Previously, a two door version had been available in the Jeep Wagoneer line (1963–67), although this had the same pillar and window configuration as the four-door Wagoneer.
Based on the Wagoneer, the Cherokee was marketed as the «sporty» two-door variant of Jeep’s station wagon. The term «Sport Utility» appears for the first time in the 1974 Cherokee sales brochure. A four-door was not added to the lineup until 1977. Other than the base model, the trim levels of the Cherokee included the S (Sport), Chief, Golden Eagle, Limited, Classic, Sport, Pioneer, and Laredo.

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 drivability. Mid-1985 and later two-wheel drive models used the same basic suspension with a single tube connecting axle ends with no differential.

Axle Gear RatiosEdit
Jeep XJs came in several standard gearing ratios:
- 3.07:1, manual transmission, I6 engine.
- 3.73:1, automatic transmission, I6, Tow Package, UpCountry Package.
- 4.56:1, automatic transmission, I4, offroad or tow package.
The Jeep XJ utilizes a coil spring front suspension with a leaf spring 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
Генеральный директор Chrysler Group Серджио Маркионне объявил на Североамериканском международном автосалоне в Детройте в январе 2011 года, что название Grand Wagoneer будет возрождено для «верхнего» семиместного внедорожника, который, по его словам, будет представлен в 2013 году. В феврале 2013 года группа планирования продуктов Jeep предприняла исследовательскую поездку в Wagonmaster, компанию, занимающуюся восстановлением и перепродажей классических Grand Wagoneer. 2 сентября 2013 года Chrysler объявил, что они отложат производство до 2015 года, чтобы позволить Dodge Durango чтобы найти аудиторию, но в то же время использовать концепцию Grand Wagoneer в качестве основы для полноразмерного роскошного внедорожника, который будет конкурировать с Cadillac Escalade и Lincoln Navigator, чьи редизайны поступили в продажу в 2014 году.
В мае 2014 года был обнародован «пятилетний план» Chrysler, который включал намерение выпустить флагманский автомобиль под названием Grand Wagoneer, который будет делиться платформой с Durango и Grand Cherokee к 2018 модельному году. Первоначально планировалось заменить Durango, Grand Wagoneer будет продан вместе с ним и Grand Cherokee. Новый автомобиль должен был быть построен на сборочном заводе Jefferson North (JNAP) Chrysler, где производились Durango и Grand Cherokee, и заполнит нишу Jeep Commander, который прекратил производство в 2010 году из-за низкого спроса.
9 июня 2015 года Fiat Chrysler объявил, что он представит новую версию полноразмерного Grand Wagoneer на своем дилерском конгрессе 25 августа 2015 года. В августе 2015 года, однако, Fiat объявил, что производство предстоящей замены Grand Cherokee будет отложено до 2018 года. Его планируется построить в Warren Truck Assembly, в то время как следующее поколение Ram 1500 будет построено в Sterling Heights Assembly. 18 октября 2016 года Jeep выпустил тизерные фотографии Grand Wagoneer, в которых указывалось, что он будет основан на третьем поколении Durango и представлен как модель 2019 года.
Этот план был вновь отложен до 2021 года.
Engine choices consisted of AMC I6 or V8 powerplants. When it was equipped with the powerful 401 cu in (6.6 L) AMC V8 engine, it would out-run just about any other 4×4 in its class, and, with 3.07:1 highway gearing, could reach speeds in excess of 100-mile-per-hour (161 km/h) (early models had 120 mph speedometers). A range of AMC engines were offered: the 258 cu in (4.2 L) inline six-cylinder, a 360 cu in (5.9 L) V8 with two-barrel carburetor, a four-barrel 360, or the 401 cu in (6.6 L) V8. The durable 401 had a forged crankshaft and forged connecting rods, as well as the high nickel content block of the other AMC V8s. The 401 was discontinued at the end of 1978. After acquiring AMC in 1987, Chrysler kept the 360 V8 in production until 1991 for the Jeep Grand Wagoneer.
Chrysler Group CEO Sergio Marchionne announced at the January 2011 North American International Auto Show held in Detroit, that the Grand Wagoneer name was to be revived for an «upper-scale» seven-seat SUV, which he said would be introduced in 2013. In February 2013, the Jeep product planning team took a research trip to Wagonmaster, a company dedicated to restoring and reselling classic Grand Wagoneers. On 2 September 2013, Chrysler announced that they would delay production until 2015 to allow the Dodge Durango to find an audience, but at the same time would use the Grand Wagoneer concept as a basis for a full-size luxury SUV that would compete against the Cadillac Escalade and Lincoln Navigator, whose redesigns went on sale in 2014.
In May 2014, Chrysler’s «Five-Year Plan» was unveiled, which included the intention to release a flagship vehicle called the Grand Wagoneer that would share a platform with the Durango and Grand Cherokee by the 2018 model year. Originally planned to replace the Durango, the Grand Wagoneer would be sold alongside it and the Grand Cherokee. The new vehicle was to be built at Chrysler’s Jefferson North Assembly Plant (JNAP), where the Durango and Grand Cherokee were being produced, and would fill the niche of the Jeep Commander, which ceased production in 2010 due to low demand.
On 9 June 2015, Fiat Chrysler announced that it would unveil a new version of the full sized Grand Wagoneer at its dealers convention on 25 August 2015. In August 2015, however, Fiat announced that the production of the upcoming Grand Cherokee replacement would be delayed into 2018. It is scheduled to be built at Warren Truck Assembly while the next generation Ram 1500 is to be built at Sterling Heights Assembly. On 18 October 2016, Jeep released teaser photos of the Grand Wagoneer, which indicated that it would be based on the and introduced as a 2019 model. The plan was delayed again.
On December 5, 2019, spy shots surfaced of FCA testing a Jeep Wagoneer using a RAM 1500 body on frame SUV; it was not known at the time if there would be a Grand Wagoneer (which would rival the Suburban and Expedition MAX) to accompany it at this point but later confirmed that they’re will be a long-wheel base companion. Due to the 2020 COVID-19 Pandemic that has temporarily halted automotive production in North America, FCA is delaying the start of production by at least three months, and is expected to debut this full size version in early 2021 as a 2022 model.
1984-1990 Jeep Wagoneer (XJ platform)
1994–1997 Jeep Cherokee (XJ) Sport (Australia)
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. Its appearance has led some to mistakenly believe that the two-door models are a short-wheelbase version of the four-door.
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 both sides. The Wagoneer Limited came with vinyl wood trim on the sides and leather seats embossed with «Limited.»
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 didn’t 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.
1993-1996 Jeep Cherokee XJ (Japan)
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. 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.

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.
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 4- and 6-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.
When (XJ) Cherokee production ended in mid 2001, the portion of the Toledo South Assembly Plant devoted to its production was slowly torn down.

The AMC yearsEdit
Jeep Grand Wagoneer
The 1971 model year included a special «X-coded» model finished in Golden Lime with unique wood-grain side panels, numerous convenience features and power assists, that was priced $1,000 than the deluxe «Custom» model.
In 1974 AMC resurrected the two-door Wagoneer as the Cherokee. This replaced the Jeepster Commando, whose sales had not met expectations despite an extensive 1972 revamp. The Cherokee appealed to a younger market than the Wagoneer, which was regarded more as a family SUV.
In 1981, the Wagoneer line was expanded to three models. The Custom Wagoneer was the basic model, yet it included a 4-speed transmission, free-wheeling hubs, power steering and power front disc brakes, as well as passenger area carpeting. A new Brougham model added an upgraded interior trim that included woodgrain for the instrument cluster and horn cover, floor mats, power tailgate window, as well as the «Convenience» and «Light» Packages. The Brougham’s exterior included a thin side body scuff moulding with a narrow woodgrain insert, roof rack, as well as bright door and quarter window frames, and a lower tailgate moulding. The Limited Wagoneer was the top-of-the line with standard Quadra-Trac, automatic transmission, air conditioning, tinted glass, power windows and door locks, cruise control, AM/FM stereo radio, extra quiet insulation, power six-way driver and passenger bucket seats with center armrest, upgraded door panels, leather-wrapped steering wheel, extra thick carpeting, and retractable cargo cover.
The basic «Custom» model was eliminated for 1983, and a new Select-Trac system became standard equipment. A dash-mounted control allowed the driver to change between two or four wheel drive. The switch activated a vacuum-activated spline clutch that was built into the front axle assembly.
The 1984 saw consolidation with the end of the Brougham model, while the Limited became the Grand Wagoneer. Thus, starting in 1984, only one fully-equipped version was available, and this would remain until the end of the Grand Wagoneer production under Chrysler. Production reached 20,019 in 1984 with just one version available.
An improved handling package was introduced in 1985 that incorporated a revised front sway bar, gas filled shock absorbers, and lower friction rear springs. A total of 17,814 Grand Wagoneers were built for 1985.
Starting in the 1986 model year, the Grand Wagoneer received a new four part front grill and a stand-up hood ornament. An updated audio system became a standard feature and a power sunroof installed by the now defunct American Sunroof Company, became a factory option. However, the most significant change was the installation of a fully revamped interior including a new dashpad, new instrumentation, new door panel design, a decorative tailgate «cap», shorter nap cut-pile carpeting, more modern headliner and visors, new leather seat cover designs and front seats that now featured adjustable headrests. Changes were made to the instrument panel that now featured square gauges, featured woodgrain overlays and contained an improved climate control system. A new two spoke steering wheel also included new stalks for the lights and wiper/washer controls on the column. The Select-Trac driveline gained a new Trac-Lok limited slip differential to send power to the wheel with the best traction. There were 17,254 Grand Wagoneers built in 1986.
The last model year developed under AMC, 1987, was also the 25th anniversary of the Wagoneer design. Standard equipment included the 360 cu in (5.9 L) V8 engine and self-sealing Michelin «Tru Seal» P235/75R 15 radial tires. The sound system included a new AM/FM electronically-tuned stereo with Dolby cassette and four Jensen speakers. The exterior featured revised woodgrained sides in English Walnut with new nameplates and V8 badges. On the inside were new tan or cordovan trims that replaced the honey and garnet colors, while the interior assist pulls on the door panels were removed. A combined 14,265 units were built by AMC and Chrysler for 1987.
XJ Wagoneer/Cherokee and the final years under AMCEdit
- Main article: Jeep Cherokee (XJ)
The Wagoneer and Cherokee names were applied to the new, much-smaller and more fuel-efficient unibody XJ platform in 1984, but high demand prompted the company to keep the old SJ-body Wagoneer in production.
The full-sized Wagoneer Limited was renamed the Grand Wagoneer.
The Grand Wagoneer remained «the gold standard of the SUV market» and it would continue in one version using the old SJ-body «for 1985 and beyond».
