So I bought a ERBE off a buddy of mine real cheap.... $150.... I was working on getting it cleaned up a bit today, replacing rusty screws, whatnot.... I have all the wheels off and I was on the phone turning one of the front axles/hex hubs with my fingers, nice and smooth, did the same with the rear, and was not smooth, it was really "clicky" for lack of a better word... Could it be the rear diff is jacked? The bearings in the rear carriers seem ok, and it runs good... For $150, I can't be mad if a diff is shot, he gave me an extra diff and a rebuild kit as well, what do you all think it could be??
