As a Dorman suspension control arm and ball joint assembly, it replaces a worn arm, joint and bushings in one piece at the front left upper position. Signs this part may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, or play at the ball joint. Diagnose the cause before replacing any parts. This listing covers the front left upper arm only, and replacing both sides together is recommended for balanced handling.
