More About Control Arm Parts & Accessories

Control arms link the wheels and suspension to the chassis, allowing the wheels to move over road imperfections while maintaining the correct steering angles needed for handling, even tire wear, and vehicle safety. Regularly inspect and replace bent control arms, loose ball joints, or worn suspension bushings to keep your suspension tight and quiet.
