• Clunking or knocking from worn bushings
• Uneven steering response caused by deteriorated rubber
• Vibration transfer through the front suspension
• Loss of suspension alignment stability from worn bushing material

Installation Notes and Tips

Verify the vehicle is equipped without Variable Damping Suspension before ordering. Confirm the front left lower rearward position and match the bushing dimensions to the original component before installation. Because mounting hardware is not included, reuse or source the required hardware separately if needed for the repair.
