Anchor the front wheel and support smooth steering travel with the Mevotech Supreme control arm CMK80355, a front right lower control arm and ball joint assembly that installs as a direct-fit replacement for the 2006-2011 Buick Lucerne and 2006-2011 Cadillac DTS. Mevotech Supreme parts are engineered in-house with application-specific upgrades for high-usage passenger vehicles, SUVs, fleets and working trucks.
The control arm connects the steering knuckle to the vehicle frame and locates the front wheel, while the integrated ball joint lets the suspension travel and the wheel steer. Worn control arms or ball joints can produce clunking or popping from the front suspension, uneven tire wear, or loose, wandering steering — if a failed control arm or ball joint is the cause, this assembly replaces it.
