Dorman - OE Solutions Suspension Control Arm and Ball Joint Assembly P/N:520-520
Keep the front right corner of your suspension properly located with the Dorman control arm 520-960, a front right upper arm that arrives with its ball joint and bushings already installed. It fits many vehicles, among them the 2007-2011 Mercedes-Benz CLS550, 2007-2011 Mercedes-Benz CLS63 AMG and 2003-2009 Mercedes-Benz E320. See the Buyer's Guide tab for the full list and engine details.
This Dorman suspension control arm and ball joint assembly directly replaces the original equipment on specific vehicle applications. Dorman puts it through an industry-leading evaluation process aimed at a smooth ride, directional stability and predictable handling.
The upper control arm connects the wheel assembly to the vehicle's chassis and pivots as the suspension moves. If a worn arm, ball joint or bushing is behind clunking over bumps, loose or wandering steering or uneven tire wear, this unit replaces all three in one piece. Diagnose the cause before replacing, and follow the vehicle service information for installation.
