Overview of popular issues

The Jeep Wrangler YJ is the first generation of Jeep Wrangler four-wheel drive small off-road vehicles, rebadging and succeeding Jeep's CJ series, which was produced from 1944 to 1986. The first Wrangler (internally "YJ") was launched in 1986 and ran through 1995. Although the new Wrangler stood out from its CJ predecessors by its square headlights, its body was a direct evolution of the preceding CJ-7, and rode on the same wheelbase. The Wrangler featured an updated interior, offered more comfort and improved safety and handling, through a revised chassis that included a wider track and a slightly lower stance.

Development of a potential CJ-7 replacement was green-lit in 1982, with engineering and design work (under Chuck Mashigan) commencing. After approval earlier in 1983, a final design freeze occurred by the fall of 1983, with CJ-7 based mules being built in late 1983 and the first production body test prototypes in the spring of 1984. By late 1985, development concluded, as the transition from pilot to series production began. In February 1986, the 1987 model year Jeep Wrangler was unveiled. It entered production that March and went on sale on May 13, 1986.

History

The Jeep YJ, sold as the Wrangler in the United States, replaced the Jeep CJ line 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 II. Jeep could not use the Wrangler name in Canada, as General Motors had used it on a truck variant and owned the rights to the name there.

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 significantly new design with a wider track, slightly less ground clearance, more comfort and improved handling. The YJ still had leaf spring suspension similar to that of the CJ – however the springs were wider, and the first Wrangler sported trackbar suspension links and anti-roll bars for improved handling and safety, making it less easy to flip by untrained or unwary drivers.

Despite the new grille, the body is very similar to that of the CJ-7, 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 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 was launched in 1996. 632,231 YJs were built through the 1995 model year, although YJs were still sold 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 1990. Power outputs at the time of introduction are 117 hp (87 kW) for the fuel injected four-cylinder, while the carburetted 'six only produces 112 hp (84 kW), albeit with more than fifty percent more torque than the smaller engine. Starting in 1991, a fuel-injected, 190 hp (142 kW) 4.0-liter AMC 242 variant replaced the AMC 258 straight-six unit. The NP207 transfer case was used only for 1987 and replaced by the NP231.

In 1988, the Sahara model debuted. The roll cage was extended in 1992 to allow for rear shoulder belts, Also that year, the YJ switched over to an electronic speedometer, outmoding the cable speedos on older YJs. Anti-lock brakes were added as an option in 1993. An automatic transmission option for four-cylinder Wranglers came in 1994, as well as a standard center high-mounted brake light. Also, the clutch slave cylinder on manual transmission Wranglers was moved outside of the transmission's bellhousing to allow for easier replacement. In 1995, the Dana 30 larger U-joints were used .

There were no 1996 model year Jeep Wranglers. The last YJs 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 straight-6 engine 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.

Common Jeep Wrangler yj problems

The Jeep Wrangler YJ, produced from 1987 to 1995, is a popular model among Jeep enthusiasts, but it has some common problems that potential buyers should be aware of.

Hydraulic Throwout Bearing: One of the most common problems with the YJ Wrangler is the hydraulic throwout bearing, which can fail and cause difficulty in shifting gears. Chrysler finally addressed this issue in the 1994 model year by introducing an external master/slave clutch setup.

BA-10/5 Transmission: The BA-10/5 transmission, standard on the 4.0L I6 engine, is known for its reliability issues. It can suffer from gear slippage, delayed engagement, and difficulty shifting, especially when the vehicle is heavily loaded or towing.

Carter BBD2 2-bbl Carburetor: The Carter BBD2 2-bbl carburetor on the 258 CID (4.2L) I6 engine is finicky and can be stubborn at times. Learning to adjust and maintain this carburetor can help, but many owners opt for Mopar's port injection kit for increased horsepower and torque.

Rust Issues: As with many older vehicles, rust can be a significant problem for the YJ Wrangler, especially if it has been driven in areas with harsh winter conditions or high humidity. Regular inspection and maintenance of the vehicle's undercarriage, wheel wells, and body panels can help prevent or mitigate rust damage.

Electrical System Issues: The YJ Wrangler's electrical system can experience issues, particularly with the totally integrated power module (TIPM). This component controls various electrical functions, and failure can lead to problems such as stalling, airbags not deploying, and power windows getting stuck. Fiat-Chrysler vehicles from 2007 to 2015, including the YJ Wrangler, are notorious for early TIPM failure.

Suspension Components: The YJ Wrangler's suspension components, such as leaf springs and bushings, can wear out over time, leading to a less comfortable ride and reduced off-road capability. Regular inspection and replacement of worn-out components can help maintain the vehicle's performance.

Interior Comfort and Quality: The YJ Wrangler's interior is known for its lack of comfort and lower quality compared to later models. The plastic-covered dashboard, for example, is prone to rattling and squeaking, and the seating may not be as comfortable as in more modern vehicles.

Fuel Efficiency: The YJ Wrangler's fuel efficiency is generally lower than that of more modern vehicles, which can be a concern for owners who drive long distances or use the vehicle for daily commuting.

Off-Road Capability: While the YJ Wrangler is known for its off-road capability, its older design and components may not perform as well as more modern vehicles in challenging off-road conditions. Regular maintenance and upgrades can help maintain the vehicle's off-road performance.

Availability of Parts: Some parts for the YJ Wrangler may be difficult to find or no longer available, which can make repairs and maintenance more challenging and expensive.

In summary, the Jeep Wrangler YJ has several common problems that potential buyers should be aware of, including hydraulic throwout bearing failure, transmission issues, electrical system problems, rust, and interior comfort concerns. Regular inspection, maintenance, and upgrades can help mitigate these issues and ensure the vehicle remains safe, reliable, and enjoyable to drive.

Are YJ Jeeps good?

It is still a great Jeep and a good platform to start off with, and because most other people are looking at CJs or TJs, it often means you can score the Jeep that started the twenty-plus years of the Wrangler's reign as the best off-road production vehicle for half the price of a similar condition CJ or TJ.

What are the common problems of a 1995 Jeep Wrangler?

Which is better, YJ or TJ?

For all intents and purposes, the TJ exemplifies the typical Wrangler look. In terms of broad performance differences, the TJ recouped some of the lost off-roading abilities of the YJ by raising the vehicle a tad and swapping leaf springs for a coil spring- suspension system.
