Hi
I have a Camarao 68RS with a 10 bolt rearaxle. And now to the question i hope someone can answer.
The axle aint proper installed, so my left rear wheel have about 3 centimeters about 1,3" between the frontside of the left rear fender fender(looks something like this, seen from the side. (o ) where the ( is the fenders and the o, is the wheel), and about 6 cm (2,6") between the backside of the fender, and on the right side, the wheel seems to be in the center, as i should be.

So i wonder how im suposed to do to correct this faulty installed rearaxle?
I tried many wheelalignment-mechanics and they only say that they dont do cars that old like my Camaro. =(

The rear axle alignment is set up by the rear leaf springs. There is a bolt/pin that goes through the springs and fits in a hole in the lower bracket. The lower bracket connects to the welded upper bracket using four T-studs (T-studs are often replaced with U-bolts that go over the axle tubes). There is nothing really to align.

If the axle slips on the leaf spring, then there will be an alignment problem. I've heard of this happening before so it's possible.

I would also make sure that the rear axle is really the problem and not the rear quarter panels. You can measure the distance from the end of the frame to the axle to look for a difference between the driver's and passenger sides just to make sure.

Good luck, hope this helps.

This happened to my Camaro on the left side.
If you have the single leaf spring, and if you have the 10 bolt rear end, you probably do, the spring can slip in the rubber padding.
The single leaf spring has only a small locating pin welded to the bottom of the leaf, A rubber pad is between the leaf and lower spring pad, there is a small hat shaped sheet metal stamping over the locating pin the leaf can slide in the rubber pads and move forward.

If you buy replacement polly spring pads, they should hold it in place.
If you don't have access to that, I would place a spacer plate on top of the spring and use no pads on top or bottom of the leaf allowing a firmer grasp of the lower plate.
Check your lower spring plates for bending too.

If you don't have at least one U bolt on each side, put them in for safety. The spring perches have been known to rip off the housing on Camaros. I would weld a small reinforcement plate between the housing and front and rear of the axle tube to streingthen the spring perch.

Hi

I've just came back from a workshop that do shimming on old cars. And he explained this for me too, as you said.
We looked at the little pin/bolt that goes thrue the lower bracket, and he said that it is possible that the pin has broken off the spring, or the car could have been in a carcrash and the body is "twisted", but it didt look like it. So hes going to measure it and check for the cause.
Otherwise i think ill buy new singleleaf springs and see if it will make it right, they could be bent also he said.

Thanks for the help guys.

The rubber padding on the bottom can allow the rear end housing to move forward. The little pin welded on the bottom of the spring is very short and can move in the rubber.
I would get rid of the rubber pads and make up steel or aluminum spacer and put it on the top of the spring leaf.
It happened on my Camaro, and I've seen it happen on others.
