We own three of these a '93, '95, '98. The '92 and '95 both have over 120K on them. We have had very good luck with them. No major repair bills so far.
Sometime after 100K the tranny will start leaking from its rear seal. I am told that this is because there is not enough fluid flow to the OD part of the tranny which causes it to heat up more. The extra heat makes the seal fail over time. This has happened on both the '92 and '95.
The D44 aluminum center axles on the '96 and up make a loud whining noise. There is a kit at the dealer to fix this.
In high salt areas the front discs rust out ('93-'95). There is a recall for this.
'93-'95 quadratrac tcase does not lock in low. '96 and up do.
My '95 w/V8,quadratrac,30" tires, 3.73 gears averages 18-20MPG...this is with K&N filter and custom exhaust. The '98 w/V8, quadratrac, 3.73 gets 15-18 completely stock. The '92 with I-6(136K), quadratrac, 3.54, stock tires still averages 20-22MPG.
Don't think you can get a V8 in 2wd. '93-'98 you can only get the V8 with the quadratrac tcase. Oh, actually I think the 5.9 limited might have come with a 242 select trac but not positive.
