I have a 85 K5 with 33's.When I turn a corner from a standstill I can here(and kinda feel) clicking in the rear of the truck.I didn't do that before I went wheelin' awhile back(I thrashed it pretty extensively) but now it does.I had put additive in the rear when I bought it cause a friend with a K5 said the factory diff(limited slip is what I believe I have) required it and I didn't know how much it had.I haven't had any problems with it except when I first got it(about a year ago) If I would brake hard while turning sharply(ie. u-turns,etc) it would bind in the rear and I would have to back-up to loosen it.Now it doesn't do that,but I am getting that clicking sound.Could it be the locker(gov-lock or whatever) and should I worry?
