Help bring back tight, controlled handling with the Mevotech Supreme control arm CMS20329, a front left lower control arm and ball joint assembly that locates the wheel and lets it pivot and travel while carrying suspension loads.

• Stamped steel construction: built to OE-level tolerances, with a protective surface treatment that helps resist rust build-up.
• Sintered bearings: designed for longer-lasting performance.
• Upgraded bushings: a solid cross section adds stiffness and durability for improved handling.
• Simple to service and install: includes a 180-degree SAE grease fitting plus a part-specific castle nut and cotter pin to secure the ball joint.
• Larger sphere design: an application-specific ball stud system with a larger sphere.

Clunking over bumps, loose or wandering steering, and uneven tire wear can be signs a control arm bushing or ball joint may need replacing. If a worn bushing or ball joint is the cause, this Mevotech Supreme suspension control arm replaces both in a single assembly. Sold individually; replacing the opposite side at the same time is recommended.
