Signs this part may need replacing: clunking or knocking from the rear over bumps, uneven or rapid rear tire wear, a rear alignment that won't stay in spec, or vague handling. If a worn or damaged lateral arm is the cause, the 905-502 replaces it. Diagnose the cause before replacing parts.
Because this arm is listed for both the left and right sides, replacing both sides together is recommended. Have the rear alignment checked after installation, and consult the vehicle service information for torque specifications and whether the original fasteners may be reused.
