Take it to a garage and they see green. I used to work in one, and the techs always argued over who got the 4x4 (of any brands). Lots of crap to wear or replace. ESPECIALLY Jeeps, if your 4x4 stops working, just removing the driveshaft to the front or be prepared to lighten your wallet quite a bit
I'd just make sure you grease the crap outta everything, check for leakage and check the u joints. The worse thing people do for their 4x4's is only use it when its needed, which for some people is like once every two years. Click it in and out in a parking lot just to make sure everything works. There nice trucks, my dad just picked up and expedition aka gas guzzler
