Background
As the manufacturer of the first mass-market utility four-wheel-drive, Jeep/Willys introduced the civilian CJ range in 1945 where it remained in production for a scarcely unbelievable 41 years, eventually falling out of favour in 1986.
The YJ you’re looking at here first hit the showrooms in 1987. The first Jeep launched under Chrysler’s stewardship, it was also the first one to be sold under the now-famous Wrangler name.
It retained the same basic layout as the earlier CJ range with a separate steel chassis and an open body, front and rear leaf spring suspension and a rear-wheel-drive chassis with the front axle being manually engaged when traction is poor. Two gearbox ratios are available, high for road use and a lower set for off-road.
Engines spanned the range from a four-cylinder 2.5-litre through to 4.2-litre straight-six. Fitted with carburettors until 1990, a fuel-injected 4.0-litre engine was introduced in 1991 in place for the older, larger capacity engine. Despite a 200cc deficit, the new engine pushes out 180bhp, 68bhp more than the one it replaced.
The other main change compared to previous Jeep models is a wider track and lower ground clearance, moves that gave the TJ a better ride as well as safer handling in extremis.
Not that the Wrangler’s lack of ground clearance is an issue with our next auction listing…
