Why does the right rear bounce, shimmy, and shake when I hit a dip or bump.
One day while on a normal drive, the right rear of the car just starting to shimmy/shake whenever I hit a dip. It has gotten progressively worse as now when I hit a dip or bump, it bounces and shakes or shimmies only on the right rear wheel. I took the car into a Mercedes repair center and he drove it, then showed me some bar under the rear and charged me $400 to replace it, however, the car still bounces/shimmies and shakes on the right rear. The car really feels unsafe at speeds above 50mph. My brother-n-law, who drive Audi, said that his Audi started doing that and it turned out to be the right rear wheel bearing. I don't want to get ripped off again and would like help in diagnosing this problem. Thanks and I appreciate any help anyone can offer in diagnosing this problem.
