Swap out a worn front left upper arm without pressing in a separate ball joint or bushings: this Dorman control arm, part number 521-851, comes with both already installed. It fits many vehicles, among them the 2006-2012 Ford Fusion, 2007-2012 Lincoln MKZ and 2006-2011 Mercury Milan. 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 assembly on the listed applications. The arm links the steering knuckle to the chassis. The ball joint is the pivot point that lets the wheel move with the suspension and turn with the steering.
- Direct replacement: built to take the place of the original equipment front left upper assembly on specific applications.
- One-piece repair: the ball joint and bushings come pre-installed, which saves time and labor on the job.
- Tested engineering: put through Dorman's industry-leading evaluation process, which is designed for a smooth ride, directional stability and predictable handling.
- Corrosion protection: additional coatings help the assembly resist rust and corrosion.
Signs this part may need replacing include clunking over bumps, loose or wandering steering, uneven tire wear and excess play at the ball joint. Diagnose the cause before you replace anything. Follow the vehicle service information for torque specs and fasteners, and have the wheel alignment checked afterward.
