A control arm bushing cushions the point where the control arm pivots, helping to locate the arm and absorb road vibration. Signs it may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, or a visibly cracked or deteriorated bushing. Diagnose the cause first. If a worn bushing is the source, this part replaces it. Consider inspecting the matching bushing on the other side at the same time.
