Replace a worn front suspension link with this Dorman control arm, part number 520-170, a front right lower arm that arrives with its ball joint and bushings already installed. It fits many vehicles, among them the 2001-2003 Oldsmobile Aurora, 2000-2005 Buick LeSabre and 1998-2005 Buick Park Avenue. See the Buyer's Guide tab for the full list and engine details.
This Dorman lower control arm is built as a direct replacement for the original equipment on specific vehicle applications. It connects the chassis to the steering knuckle and pivots on its bushings, while the ball joint lets the knuckle move with the suspension and turn with the steering. Dorman puts the design through an industry-leading evaluation process intended to deliver a smooth ride, directional stability and predictable handling.
- Direct replacement: designed to take the place of the original assembly on the listed applications.
- Complete repair: the ball joint and bushings come pre-installed, which helps save time and labor.
- Quality engineering: put through industry-leading testing aimed at a smooth, stable and safe ride.
- Durable design: additional coatings help resist rust and corrosion.
Signs this part may need replacing include clunking over bumps, wandering or loose-feeling steering, uneven tire wear, play in the ball joint, and cracked or torn bushings. These symptoms can have other causes, so diagnose the problem first. If a worn arm is the cause, this assembly replaces it. This listing is for the front right lower position and is sold individually. Replacing the left and right arms together is recommended for even handling.
