One rear wheel sticks out 1/2" more than the other

Aside from a bent frame.....what can cause the rear wheel to stick out more than another. Shims in the trailing arm maybe?

Maybe a shift on the body mounts? Ot bad body mounts?

I din't know if there was a way to pull one side in/out to even things up a bit.

1/2" is a lot. Check how many shims you have on the inboard/outboard side of each trailing arm. Maybe one arm is bent ?
I'd start with an alignment and then loosen the body mounts and move the body on the frame, most likely you want to replace the mounts while you're at it....

I got an alignment a while back and they never said anything. I ordered some new body mounts last week so I'm definetly going to see if I can shift the rear a little when I install them.

But I'll check the shims for sure.

If you remove the door sill plates, you will see 2 holes about 1/2 diameter (they may have plastic plugs in them). There are also these same holes in the frame perimeter just below them. If you look through, these holes should all be aligned. If not, your body is not on straight.

Look the frame over for damage that was repaired (or not repaired). These cars have been on the road a long time, and you never know for sure what they have been through.

it could also be something stupid like a rim that is narrower than the other three, i had a set of rally sport rims that ended up like that, never noticed it till i got it aligned. so it might not be the case for you. Just an idea

Shims and alignment don't change the wheels location. It depends on the halfshaft and that's a fixed length. However, camber settings CAN make it look like one side is further outboard if you look at the top of the tire and one side has less negative (or more pos.) camber and also corner height will have an effect. That said, 1/2" is a lot. Are you sure your halfshafts are the same length? Could be someone swapped the halfshaft for the wrong one. Could also be the wheel is pulling outboard because of a lot of stub axle play (or even a missing snap ring), could be a misaligned body (check the jig holes like mentioned before)

I know that early C3's, espcially '68 Vettes had issues with the body not being centered on the frame.. However, that changed during the production.. My Racing C3's body is centered in the rear but is about 1/2 inch off in front.. The body on my yellow C3 is perfect in front but is a little bit to the left in the rear... Upon closer inspection, many early C3's have that issue..

How does your car relate to factory tolerances? It has an aftermarket tilt front end? There's no telling what happened or even if the frame is straight. So because yours is off, exactly what does that say for other cars? ZILCH

The original poster has an 82 so I don't think he will have problems that were related to early production.

I have a 68 and my car is dead on the alignment pin holes. These tooling pins were used in the factory to position the body onto the frame. If they are not matched it is a clear indication that the body has shifted on the frame.

might have something to do with your car being crashed and it having a replacement front end.......

I pulled the sills and look through the openings and the driver's side is off a hair and the passenger side is dead on.

I had an alignment done, and the wheels are all the same thickness. I'm 99% positive those are the original half shafts.

I's not really THAT noticable, but the fact that I know it's there bugs me.

I caught this when I was trying out some billet 1" spacer adapters a while back and noticed the passenger tire stuck out pass the fender and the drivers side was flush. But I decided not to use the spacers.

I guess I'll live with it for now, it's either a bent frame or trailing arm...

Thanks!

Is the rear wheel sticking out a half inch more in reference to the frame, or does it stick out half inch more in reference to the fenders? Check where the rear splash guards mate up to the fenders (behind the back wheel). I found mine 'shimmed' with kittyhair, causing my wheel to appear a half inch "In" referenced to the other side.

Thanks for the help, the wheel is sticking out more in reference to the fenders. I'm getting ready to change the replace the body mount bushings and would like to tackle this issue too.

Are you guys 100% sure that shimming the trailing arm in/out wouldn't fix the problem? Like maybe remove one from the wheel sticking out and moving to the other one to "even" things up a bit?

I'm 99.9% sure those are the original halfshafts on my car so I don't think one is longer than the other.

I may try it to see what happens.....what will this affect on my rear suspension and alignment by adding/removing shims?

Thanks

P.S. does anyone have an untouched original that can tell me where the wheel is "supposed" to sit in the fender well in relation to the top of the rear fender? Like "flush" or 1/2" back?
