I searched and couldn't find anything on this, and its a pretty weird problem.

A couple nights ago, we were swapping rear ends in my buddy's car ('86 Trans Am) because he blew up the previous one at the track a few weeks ago. It was just a swap from a 10-bolt to another 10-bolt.

For the most part it all seemed to go fairly smooth, at least what I was there for, but after the brakes were bled and the car was sitting on the ground again, the rear end seemed to be sitting way off center? Like, probably 2" over towards the drivers side. At first we thought it was because we forgot to put the isolators back on the springs, but they put them back today (I wasn't around for this though) and said it didn't seem to help?

Anyone have this problem before? I've never heard of this happening before - didn't happed the last time they did this on that car, and didn't happen when I did mine either?

 

Is the pan hard rod bent? Are you sure you have it mounted in the right holes?

 

LCA's line up straight? 2" is a fair bit, you'd have major bind in the LCA's when driving normally i'd think.
Yea, panhard bent or something is what i'd think of...

 

This my car. I have a Hotchkis adjustable panhard bar adjusted all the way over and its not bent. The control arm's are straight and the driveshaft is good. No noises or anything funny. Its in the right holes and is over 1" to the driver's side.

 

If the car has been lowered with lowering springs or just plain old sagging old springs it will cause the rear end to shift to the drivers side. As has already been mentioned an adjustable PHB will correct this.

I guess it could be saggy springs - but the old rear I took out last week was centered. And I do have an adjustable PHB.

 

bent panhard mount on the new rear end?
