Designed for a smooth ride and predictable handling, this Dorman control arm (part number 521-159) is a front left lower suspension control arm that arrives with its ball joint and bushings already installed. It fits many vehicles, among them the 2007-2009 Ford Focus Europa, 2007-2013 Volvo C30 and 2006-2013 Volvo C70. See the "Vehicles it fits" section for the full list and engine details.
The lower control arm connects the steering knuckle to the vehicle's chassis. Its ball joint lets the knuckle pivot as the suspension travels and the wheels steer, while the bushings allow the arm to move at its mounting points.
- Trustworthy replacement: This Dorman suspension control arm and ball joint assembly directly replaces the original assembly on specific vehicle applications.
- Complete repair: Each assembly comes with the ball joint and bushings pre-installed, saving time and labor.
- Quality engineering: It went through Dorman's industry-leading testing process, which is designed to deliver a smooth, stable and safe ride with directional stability and predictable dynamics.
- Durably designed: Additional coatings help resist rust and corrosion.
Signs this arm may need replacing include clunking or knocking over bumps, loose or wandering steering, uneven tire wear, and play in the ball joint or worn bushings. If a worn arm, ball joint or bushing is causing the problem, this assembly replaces all three in one piece. Replacing both front lower arms together is recommended for even, balanced handling. An alignment check is recommended after installation.
