My car is sits high on the rear pass side.... Could you briefly explain the adjustment procedure?

Thanks

take it to an alignment shop...haha j/k.

I don't actually know how to do it, but you have the two big cams on the center of the bottom A arms. They adjust the lean of the tire. I think that is called camber. Basically the cams can push the bottom of the tire in and out. If you have more camber on one side than the other you get the lean.

I guess on a tire that wide that the alignment could make a material difference.

Your first response is probably the best advice - probably not something I should attempt alone in my garage....

Thanks

One other thing you should check.

Count the threads below the nut on the bolt that extends down from the rear springs.

All those bolts do is adjust where the body lies on the car. If one side has less threads showing the body should be lower on that side.

It is fairly common for the rear of the car to be lowered using those bolts. It is a tougher job to lower the front of the car. You have to remove wedges from the spring or something.

A C5 Corvette has the bolts like the rear on the front as well.

USAF,

My front driver/passenger height is within 1/32 of an inch difference to the wheel well lip

I'm 1/2 in higher on the rear passeng side. the spring locking bolts on the respective sides are visually within one thread count difference from each other (appx 1/16 of an inch). The bushing compression looks equivalent side to side.

Any idea on what would be consider normal manufacturing tolerance? 1/2 inch seems pretty sloppy to me.
