The V6 2.8 was replaced in 1987 by the 4.0 inline 6. (The four-cylinder Turbo Diesel was available from 1985-1987.)
The New Process NP-207 was replaced by the NP231J (could be considered an evolution though, rather than a replacement).
The NP-229 transfer case was replaced in 1987 by the NP-242.
Transmissions were:
1984-1987 4-spd. Aisin Warner AX-4 (mostly 4 cyl.)
1987-1989 5-spd. Peugeot BA-10 (mostly 4.0 sixes)
1984-1994 5-spd. Aisin Warner (mostly 4-cyl.)
1989-1999 5-spd. Aisin Warner (6-cyl.)
1984-1991 3-spd. auto Chrysler 904 & 909 (optional; 6 & 4 cyl.)
1987-1991 4-spd. auto Aisin Warner (optional; 6 cyl.)
Wing windows or “wind wings” disappeared.
So there were a number of changes, but they were to the engine and drive train. My reference says that the best bet is a Cherokee made after 1987 (when the 4.0 came out). Fours are not powerhouses, and some may consider them “crap”. Stay away from the 2.8 V6, which had marginal output and a reputation for major problems. Cracked heads were very common. The T-4 four-speed (1984-1986) had a marginal reliability record, as did the T-5 from the same era. The worst, according to Illustrated Buyer’s Guide: Jeep, was the Peugeot BA-10 five-speed (also in Wranglers). “One experienced Jeep mechanic called the BA-10, ‘a grenade with the pin out and the safety handle taped down with old Scotch tape.’” Also, the NP-229 transfer case (mostly in the Wagoneer or Limited models) had to be engaged 10 miles per month for proper lubrication.
So there are aome years to avoid. But you’ll notice that the Cherokee was constantly improved with a number of changes that took place over the years.
The basic body has not really been changed at all. It sort-of evolved. But they all look pretty-much the same, after taking into account the changing styles and fashions that take place over the years.
HomeSlice: If you’re really that upset, have you signed the petition?
(BTW: There’s a link at Jeeps Unlimited to the DC feedback page. Unfortunately I don’t remember which thread.)
Oh yeah, a minor board skirmish is taking place between some JU posters who raided the Amigo board, and Amigo drivers who jumped over to JU. Most people are trying to be civil and get along, but there are some insults, claims and counter-claims. All in good fun, eh?
