Jack the car up, put jack stands under the rear end. Start the car, put it in gear and give it some gas. You should be able to see if it is a bent rim, bad tire, or drive shaft problem.




I did this once when I had a bad vibration in a ONE ton Dodge truck. You'd think the mass of a truck that heavy wouldn't vibrate much. It turns out that one of the FREE tires a buddy gave me was on a seriously bent wheel. I'm talking a wheel that was bent at least 1 1/2 inches! After pulling the wheel, I could clearly see the bend in the center section. I looked at the other three wheels and two others were AFU as well.
SOME buddy, huh???
