I have had electrical, transmission, and brake problems with mine. Plus I agree with Frank about it eating tires and spinning out easy in ice and snow.

I just sold my TJ : ( But picked up an oilburner : ) Anyway, you will want to look our for a leaky header, a VERY common problem in those years. Not really anything you can do but wait. Also you may want to check witch axle you got in the back. If it is the dana 44 you are good to go if you ever decide to lift to the 33's. If it is the 35, you may want to think twice. Nice Jeep!

it was then my dayli driver, but now I have mersedes Geleaenderwagen 300gd as daily driver.

Thanks for the info everyone. I know all about the handling of these things in ice and snow. As I said, I've owned several before, just not a 4.0 TJ yet.
Miller - interesting information. I find it funny that people would rate the interior quality of a Jeep low. What interior? Were they concered about the velcro peeling off the carpet?

If you are only looking for 33's, go with a body lift. Nothing rubs and it looks good, with no odd looking fender mismatch or gaps to look thru to the other side.

U-joint wear is same as stock, and no alignment issues or bump-steering like you get with a suspension lift.

Inexpensive, too.
Above 3", suspension lift is necessary.

The 4.0 TJ is a good package, but you shouldn't sink it to the headlights like you could the carb motors.
