I just got my truck back from the tranny shop. Drives great now, the clunking it was making in 4wd was the transfer case hitting the cross member. The mechanic put in some shims and took care of that. The 4 wheel drive ligh in the instrument cluster even works now. Now here's the question, when I touch the locking hubs after driving (not engaged) they feel warm. I also here a tic noise sometimes but I'm not sure if that's coming from the hubs or something else (like my review mirror, something is loose in it) Thanks for the help.
