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.

Mine is like stock or better over bumps. Now if I can stop my catback from banging against the frame on bumps and turns, I'll be fine.

Did you read the name of your thread? I mean, come on bro', choose your words more carefully!

You really need to describe your problem a little better to get any kind of a diagnosis . . .

well I have 4:10s and 31 spline axles and my rear doesnt seem to make any noise or anything...what kind of noise are you talking about like a clunk or a noise as if something is hitting through travel of suspension.

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.

I could buy gears,axels and all that stuff, or I could keep supporting my g/f I guess it is all a choice of wich REAR I would rather get.
