Signs a control arm may need replacing include clunking or knocking over bumps, uneven tire wear, wandering, or an alignment that won't stay in spec. Other suspension parts can cause similar symptoms, so diagnose the cause before replacing. Consult the vehicle service information for the correct fasteners, torque values and whether the original fasteners may be reused. A wheel alignment check after installation is recommended.
