What? GC's are great expy rigs.
The 5.2L v-8 is fantastic, and with the light weight of the ZJ, powerfull. D-trane... The rear dana 44 a has an aluminum center section, but still much stronger than a dana 35...

Dana 35, your funny... The front is an LP 30, but plenty strong for up to 31's and no lockers IMOP. Now, you have a nice v-8, and a descent tranny, and OK axles. The t-case is a 249 fulltime case. easily replaced with the part-time 231, or the better IMOP 242 part-time full-time case. I have a 231 with an sye and TW shafts behind my 5.9L grand. No problems, i love the set-up. The gears are 3:73's, and work fine with 33's, I've run up to a 35 without problem, though had it out of OD a lot. The interior is grand with many options avail. including leather, rear split seats with head rests, power heated front seats, climate control, and sunroof to name a few. They were even available in '98 only with a special limited edition 5.9L 360 V-8. In that year they were they fastest SUV period. Road and track tested the 5.9L against the new escalade, and the driver's couldn't get enough of the JEEP. The power is rediculous, I know, I have one.
The small cherokee, I've had 4 of them, is nice to wheel, and is great little off-roader, but the back seat is a joke. Straight up position, forget anybody riding back there for any period of time, including kids. The grand is a bit bigger, with much more comfortable interior, without feeling and driving like a big SUV... I also owned a Yota LC 80... a behamouth, and Slooooowwwww.
Stock, theyll do just fine with a 4" lift and 33's. 4:10 gears work well, or stick with stock.
Things that go wrong at 100,000 miles;
-climate control blend door
-CV axles in the front (can be replaced with the easily found 760ed uv joint axle shafts, better yet just grab a HP 30 out of a little cherokee for less than a $100 bucks with the shafts already in there.)
-rear dana 44A pinion bearing, you'll hear it at interstate speeds with the radio off, comming from the rear if there is a problem. Other than that, they're just a grand idea of an expedition rig.
The 44A hasn't a locker available anymore, but mine has a limited slip that works just fine. An 8.8 out of a ford works well as a complete replacement.
here is a pic of mine with ARB, MM winch, 2" lift and 255x70x16" tires on stock rims.
Here is a sweet expy rig all done up
Sorry for the HighJack, but basically, you can easily build any Jeep. Huge after market and stock part availability. Lots of power, and engines that hold up as well as the Japanese. The drive-trane can be strengthened using avail. stock parts fro other Jeeps...
Gears need to be changed on any vehicle to get the best performance out of bigger tires. That's just a fact of life for any vehicle that is lifted and bigger tires added.
