Axle not centered in car - Lateral-g Forums

I think the "easy" way is to move the spring perches on the rearend. Not sure that is the "right way".

I would say that you need to measure both the body and frame... and see where the discrepancy is first.

Was the differential centered before you did the bushings ?? Do you know if the car has ever been in an accident ??

Looking for the "easy way" doesn't necessarily mean the "correct way" to solve your issue. I would not recommend moving the spring perches... nor would I ever recommend using a different offset for a single wheel... those are just band-aid fixes that do not solve your issue.

moving the spring perches is a perfect way to solve the issue, assuming they were welded in the wrong place, It, huh, happened to this guy, huh, I knew once, yeah something like that.....

I think like Chicane said you gotta figure out what is off about the car first, before you take any corrective action, otherwise the "fix" might cause other problems.

It doesn't take that long to run a couple plum lines and measure a few suspension points to get a pretty clear picture of what is off. I had a similar problem with the rear end in my car being offset to one side about 1/2". I was able to figure out it is more of a body issue than a suspension frame issue by running a few lines and measuring.

Actually, the 'correct' way to fix this is to have a new housing done, with unequal length axles. The rears are off center slightly to the pass side so that the shaft has a straight-shot on the pinion yoke, the pinion being to one side of the ring gear. This is more 'defined' when using a 9", fyi. The reason this is done by GM is so that the axles are the same length, less parts to manufacture.

Some correct this by making the rear overall shorter, and using a spacer on the drivers side. Others just live with it the way it is.

I have never heard of anyone doing this. Especially without finding out why it's off although it is common to find 1/2" difference. It is usually fixed by making a few minor adjustments but nothing as extreme as have a new axle housing made.
