Jeep Wrangler YJ history (1987–1995)

Jeep Wrangler YJ history

Jeep revealed the Wrangler at the 1986 Chicago Auto Show as a 1987 model to replace the CJ-7. The YJ kept the CJ-7's 93.4-inch wheelbase and leaf-spring axles but added a wider track, a lower center of gravity and a more comfortable interior — answering buyers who wanted a compact SUV with more creature comforts.

Its rectangular headlamps set it apart from every Jeep before and after it. Production began in Brampton, Ontario, in March 1986 and moved to Toledo after Brampton closed in 1992. The fuel-injected 4.0-liter inline-six replaced the old carbureted 258 for 1991.

The YJ ran through the 1995 model year; there was no 1996 Wrangler, and leftover YJs were sold into mid-1996 before the TJ arrived. Jeep says the YJ sold about 630,000 units.[1],[2],[3]

What to check before you buy one

• Check the frame near the rear spring hangers and the body tub floors for rust, and the windshield frame hinges.
• Confirm the engine against the VIN engine code — 1991-and-later 4.0-liter sixes are the most sought after, and swaps are common.
• Look at the leaf springs and shackles for sag and wear, and check for lift kits and the steering geometry that goes with them.
• Confirm the axles — a Dana 44 rear is worth more than the common Dana 35.
• Use the VIN to confirm the factory engine, transmission and package equipment where data exists.

How to verify a Jeep Wrangler YJ's factory options

Every YJ has a 17-character VIN. CarWhere checks it for licensed factory build data and, when it exists, lists the equipment the Wrangler was built with — engine, transmission, axle ratio, top and option packages. Coverage for 1980s and 1990s VINs is thinner than for recent vehicles.
