2001 Impala Rear Shimmy
 

I have an 01 Impala Police Model with approx 115,000 miles. The car runs and seems to drive fine on a good smooth road, but as soon as I hit a bump or grooved pavement it seems to jerk and shimmy in the rear end. I know the bearings are good, but can't seem to pinpoint where the rest of the problem is. Would trialing arm bushings or rear struts cause this? Any advice would help. Thanks[/align]

You have a bent trailing bar. Look under your car to the right. Have you hit a curb turning lately
