Replace a worn front right lower arm in one step with the Dorman control arm 521-646 from Dorman - OE Solutions, which arrives with its ball joint and bushings already installed. It fits many vehicles, among them the 2007-2016 Chevrolet Silverado 1500, 2007-2016 GMC Sierra 1500 and 2007-2016 Chevrolet Tahoe. See the "Vehicles it fits" section for the full list and engine details.
The control arm connects the wheel assembly to the vehicle's frame, and its ball joint serves as the pivot point for steering and suspension travel. This Dorman suspension control arm and ball joint assembly directly replaces the original equipment on specific vehicle applications, and it has gone through an industry-leading evaluation process intended to deliver a smooth ride, directional stability and predictable dynamics.
- Trustworthy replacement: built to take the place of the original assembly on the listed applications.
- Complete repair: the ball joint and bushings come pre-installed, saving time and labor.
- Quality engineering: put through industry-leading testing aimed at a smooth, stable ride.
- Durably designed: additional coatings help resist rust and corrosion.
If a worn ball joint or bushing is behind clunking over bumps, loose or wandering steering, or uneven tire wear, this assembly replaces those components along with the arm. It is sold individually for the front right lower position, and replacing both sides together is recommended.
