A Dorman lower control arm connects the steering knuckle to the vehicle's chassis. It lets the wheel travel up and down while holding it in position. Signs that it may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, and a worn ball joint or bushings. If a worn arm is the cause, this assembly replaces the arm, ball joint and bushings in one piece.
