its really just a simple question. ever since i got the rear donr (gears posi and axles) when im going over bumps the rear bangs a bit harder over it. like the front part of the car goes over smooth and the rear bangs over it.

is this normal sound on a built rear? just sounds like a bang not real loud but pretty noticeable.
 
would a posi units make any more of a banging type noise then stock unit?

i dont see why it would, but thats why i want info from those that installed posi units.
 
The only noise I get like that is when the rear bumpstop bottoms out. Like when I got 4 people in the car 3 full nitrous bottles in the trunk and hit a BIG pot hole. But that's from the lowering springs. Now I guess it's possible that if your pinion angle was off it could make a popping noise when going over bumps. I also know some lockers make funny sounds but that really is more a case of where you normally lift for bumps causing a locking unlocking action.
 
I don't have a built rear, but does this problem happen when you are into the gas or does it happen when you are not? I could see a problem with new control arms and/or gears when into the gas. Hope you figure out your problem.
