Jeep Wrangler YJ

The Jeep YJ, sold as the Wrangler, replaced the much-loved but slower-selling Jeep CJ in 1987. It was a new design with a longer wheelbase, less ground clearance, and more comfort, and some of its inspiration came from its stable mate, the Jeep Cherokee, rather than from its CJ predecessor alone. (This prompted some Jeep purists to interpret the YJ as a "yuppie Jeep" upon the model's introduction.) 632,231 YJs were built through model year 1995. The YJ was replaced in 1996 by 1997's TJ. YJs are easily identifiable by their rectangular headlights.
 
 

 

The YJ used a 2.5 L AMC I4 or optional 4.2 L AMC I6 until 1991. That year, a fuel injected 180 hp (134 kW) 4.0 L variant replaced the 112 hp (84 kW) 4.2 L straight-6.
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 stop light.

  

 

On August 5, 1987, American Motors was bought by Chrysler, and the Jeep marque became a part of Chrysler's Jeep/Eagle division.

 

Engines

The YJ came with the AMC 2.5L I4 engine standard and the AMC 4.2L(258) I6 optionally until '89. In 1990, the 4.0L I6 was introduced.

Transmissions

The AX-5 and BA 10/5 were used with the I4 and I6. The BA 10/5 was discontinued in mid-1989 and the AX-15 was used with the 4.2L I6 and 4.0L ever after. The TF 904 3 speed automatic was used with the I4 and the TF 999 was used with the I6 engines.

Transfer Cases

The NP-207 was used in 1987. After 1987, the NP-231 was used.

Front Axle

A reverse cut Dana 30 was used as the front axle in the YJ.

Rear Axle

The factory only used the Dana 35c in the rear of the YJ.
