Yj 1987 to 1995
The Jeep YJ, sold as the Wrangler, replaced the much-loved but slower-selling Jeep CJ in 1986 and was built in Brampton, Ontario, Canada, until the plant closed on April 23, 1992. Production was then moved to Toledo, Ohio, using the same plant that produced the Willys Jeeps during World War 2. American Motors Corporation (AMC) had designed the new Jeep to be more comfortable on-road in an attempt to attract more daily drivers. It was a new design with a wider track, slightly less ground clearance, and more comfort. The YJ still had leaf spring suspension similar to that of the CJ - however the springs were wider, and the YJs sported trackbars and swaybars for improved handling. Despite the new grille, the body is very similar to that of the CJ7, and it is interchangeable with some minor modifications. The YJ also was given a larger windshield over the CJ. The YJs are easily identifiable due to the rectangular headlights, disliked by some Jeep aficionados, and the fact that the wiper blades rest on the windshield giving this version a distinctive look. The blades rested on the windshield due to the now wider arc of the blades to clean the larger windshield. These two changes were later removed when the TJ changes came about in 1996. 632,231 YJs were built through model year 1995, although YJs were still produced into mid-1996, bringing the total production number to 685,071 units.
The YJ used a 2.5 L AMC 150 I4 or optional 4.2 L AMC 258 I6 until 1991. That year, a fuel-injected 180 hp (134 kW) 4.0 L AMC 242 variant replaced the 112 hp (84 kW) 4.2 L 258 CID straight-6. The NP207 transfer case was used only for 1987 and replaced by the NP231.
The roll cage was extended in 1992 to allow for rear shoulder belts, and anti-lock brakes were added as an option the next year. An automatic transmission option for 4-cylinder Wranglers came in 1994, along with a center high-mounted brake light.
In 1994, the slave cylinder on manual transmissions was moved outside of the transmission's bellhousing to allow for easier replacement, and in 1995 the Dana 30 larger U-joints were used [front axle U-joints (297x) and rear pinion U-joint (1330)]. For the 1992 model year, the YJ switched over to an electronic speedometer, outmoding the cable speedos on older YJs. 1995 was the only model year to have a fully galvanized frame and body.
There were no 1996 model year Jeep Wranglers. YJs produced in early 1996 were sold as 1995 model years, but featured a few new parts not seen on any earlier YJ. This included the new TJ bumpstops on the hood (rubber boots vs the traditional U-bars), reinforced tailgate hinges, and some even had rear TJ bumpers. Some also got the newly tuned I6 that was designed to run quieter in preparation for the TJ.
Top options for YJ were the same as those offered on TJ. A Soft top with "half doors", featuring soft plastic zipper windows came standard (windows could be removed completely from these doors). Full-frame doors with conventional glass windows were optional on soft-top models. Hard tops with rear wiper and defroster were optional, but came standard with full-framed doors. The YJ featured large mirrors with manually adjustable arms on half-door models, while full-framed doors received smaller adjustable mirrors with fixed arms (which were mounted further away from the door corner, compared to the larger-style mirrors). Depending on year and interior color, Jeeps could be had with the top colors in black, white, tan and gray. Roll-bar padding normally matched top color, with the exception of white tops.
