A clunk over bumps or loose-feeling steering can come from a worn arm or ball joint, though worn parts elsewhere in the suspension can give similar symptoms. With the engine off, look at the bushings for cracks or tears first. This listing is the front left arm, one of a pair across the axle; the front right is a separate part, and both are normally replaced together.
Fits
It is a direct replacement for the original equipment on the 2006-2011 Buick Lucerne and the 2006-2011 Cadillac DTS.
