Worn control arm bushings or a failing ball joint can show up as clunking or knocking over bumps, vague or wandering steering, and uneven front tire wear. If those signs trace back to the front right lower arm, this assembly replaces it. Sold individually; the left side is a separate part — replace as directed by the service procedure.
