Tighten up your front end with the Mevotech Supreme control arm and ball joint assembly (CMK80354), a direct-fit front left lower unit for the 2006-2011 Buick Lucerne and 2006-2011 Cadillac DTS. This one-piece assembly locates the front left lower suspension and pivots the steering knuckle, helping keep wheel alignment stable and ride quality controlled.
Complete, faster install: the ball joint arrives pre-assembled into the arm for a ready-to-bolt solution, and a part-specific nylon locking nut is included to speed the ball joint installation.
Longer ball joint service life: additional surface treatment helps guard the ball joint against rust build-up.
Cast aluminum construction: built to OE-level tolerances, with Mevotech Supreme validated through in-house and third-party durability testing.
This Mevotech Supreme lower control arm is engineered for high-usage passenger vehicles, fleets and working trucks. Signs the original may need replacing include clunking or knocking over bumps, wandering steering, or uneven front tire wear; if a worn control arm or ball joint is the cause, this Mevotech Supreme suspension control arm replaces it. Sold as a single left-side assembly.
