I had a person who was following me say that I had a nice ride but he noticed that I had a wobble in the right rear. I also noticed that last time I cornererd hard under power that it seemed to swing under the car. I looked under no loose or missing bolts. Lugs nuts tight. Any Ideas what I should check Thanks

could be a bent axle...but before we start the guess work...tell us about your rear suspension
4 link, 3link, 5 link IRS etc

sounds like a bent axle. was your doner hit in the rear? you can check it by putting the car on jackstands and have someone run while you watch the wheels rotate. if you have to replace the axle you might as well do the rear end clutch pack at the same time.....mike

Seems simple enough, but is the wheel sitting flush against the axle face and are all your lug nuts right ?

I had a bent RR axel and the wheel wobbled.
The hardened bearing surface on the axel was also failing.
Replaced both axels.

Could be as simple as a bent rim,out of round tire or bent axle. Jack up rear and spin the wheel. Next take off wheel and do the same. This will tell if its the axle or wheel. Find its the wheel take it to a tire shop so they can check the rim and tire for being bent or belt broken in tire causing out of round. Unless you hit something to damage rim or axle and since this is a new problem its most likely tire bad.

Control arm bushings would be a good guess and you can usually feel the car yaw when you come on and off power. This will also cause the axle bearings to wear. I don't know quite how to check for bent axle without pulling it out, but it would also cause the bearing to fail.
