Help your front suspension ride smoothly and track true again with this Dorman control arm, part number 521-020, built for the front right lower position on the 2003-2007 Cadillac CTS. See the Buyer's Guide tab for engine-specific details.
This Dorman suspension control arm and ball joint assembly went through an industry-leading evaluation process aimed at a smooth ride, directional stability and predictable dynamics.
- Trustworthy replacement: directly replaces the original assembly on specific vehicle applications.
- Complete repair: the ball joint and bushings come pre-installed, saving time and labor.
- Durably designed: additional coatings add rust and corrosion resistance.
A lower control arm links the chassis to the steering knuckle. It lets the wheel travel up and down while holding it in position, and the ball joint acts as the pivot as the wheel steers. Signs this part may need replacing include clunking or knocking over bumps, loose or wandering steering, vibration and uneven tire wear. If a worn arm, ball joint or bushing is the cause, this Dorman lower control arm replaces all three in one piece. It is sold individually for the front right lower position, and replacing both sides together is recommended.
