rear end help!!!
I have a 2000 4x4 7.3 regular cab long box. I was backing out of my parking spot today and hit my brakes kinda hard and all of the sudden my truck would not move. I put it in drive and really stepped on it and something towards the rear end would clunk and id only move an inch. When I put it in neutral me and 2 friends tried to push it and it wouldn't budge an inch. Called my dad and he said try it in 4x4. So I put it in 4 wheel drive and stepped on it. Didn't want to move but then something in the rear end broke free so I could drive again. When this happened a buddy said my leaf springs were bouncing like no other. It moves in 2 wheel drive and 4x4. It feels like something is catching while the wheels are turning and there's a LOUD scream when I'm moving. Got it home and parked it. Talked to some people and no one is exactly sure what it is. Some have said suspension, trans, transfer case, differential and brakes. Breaks don't smell, not leaking any fluids and drive shaft is firm like normal. Does anyone have any idea what the heck the problem is???
