Help your front suspension ride smoothly and track true with the Dorman control arm, part number 521-073, a front left lower control arm with the ball joint and bushings already installed. It is built as a direct replacement for the original equipment on the 2007-2015 Mini Cooper. See the Buyer's Guide tab for engine and trim details.
Dorman puts this assembly through an industry-leading evaluation process aimed at a smooth ride, directional stability and predictable handling.
- Direct replacement: designed to take the place of the original lower arm assembly on the listed applications.
- Complete repair: the ball joint and bushings come pre-installed, saving time and labor.
- Tested engineering: went through industry-leading testing intended to deliver a smooth, stable and safe ride.
- Corrosion protection: additional coatings provide rust and corrosion resistance.
Signs a lower control arm or its ball joint may need replacing include clunking over bumps, loose or wandering steering, and uneven tire wear. If a worn ball joint or bushing on the front left lower arm is the cause, this Dorman suspension control arm and ball joint assembly replaces the whole unit in one piece. A wheel alignment is recommended after installation, and the vehicle service information should be consulted for the correct fasteners and torque values.
