New to the forum, have read alot of info here got a decent problem so now I'm a member. I have a clicking noise coming from rear of truck. Decided it would be a good time to drain the rear differential. Loosened the bottom drain plug and figured the side fill plug would come out just as easy. Wrong! I've tried everything to get it loose and got no where. So I'm parked at a stand still, with no gear fluid untill I figure out how to get that plug out. Any ideas? Used liquid wrench impact and got nothing.:suicide:
