A control arm links the wheel assembly to the vehicle's chassis and lets the wheel travel with the suspension. Its ball joint provides the pivot point for steering. Signs this part may need replacing include clunking over bumps, loose or wandering steering, vibration and uneven tire wear. Have the suspension inspected to confirm the cause before you replace anything.
This listing is for one arm for the front left upper forward position. The right side is sold separately, and replacing both sides together is recommended for balanced handling.
