This Dorman suspension control arm and ball joint assembly is built as a direct replacement for the original assembly on specific vehicle applications. It goes through Dorman's evaluation process, aimed at a smooth ride, directional stability and predictable dynamics.
As the Dorman lower control arm for the front right forward position, it connects the chassis to the wheel through its ball joint. This lets the wheel move up and down with the suspension while helping keep it in position. Signs this part may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, or play in the ball joint.
