Each Dorman suspension control arm and ball joint assembly goes through an industry-leading evaluation process. That testing is aimed at a smooth ride, directional stability and predictable dynamics.
- Trustworthy replacement: directly replaces the original assembly on the listed applications.
- Pre-assembled: arrives with the ball joint and bushings already installed, which saves time and labor.
- Durably designed: additional coatings provide rust and corrosion resistance.
The control arm connects the steering knuckle to the vehicle's chassis. It lets the suspension travel while holding the wheel in position. The ball joint is the pivot that lets the knuckle turn and move with the suspension.
Signs this part may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear, and cracked or worn bushings. If a worn arm, ball joint or bushing is the cause, this assembly replaces all three together. Consult the vehicle service information for installation steps and torque specifications.
