Keep your front suspension tight and your steering precise with the Mevotech Supreme control arm and ball joint assembly (CMS501090). This front left lower unit installs as a direct-fit replacement for the 1997-1999 Cadillac DeVille, 1997-2002 Cadillac Eldorado, and 1997 Cadillac Seville. The control arm locates the wheel and positions the front suspension, while the integrated ball joint provides the pivot the steering knuckle needs to turn and travel.
- Stamped steel construction: engineered to OE-level standards, built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks.
- Ball joint built in: this Mevotech Supreme lower control arm combines the arm and ball joint, so both are replaced together in one part.
- Corrosion resistant: a protective surface treatment helps resist rust build-up.
- Labor Saver install: includes the part-specific castle nut and cotter pin to secure the ball joint to the vehicle.
If a worn front left lower control arm, its bushings, or its ball joint is the cause of clunking over bumps, loose steering, or uneven tire wear, this Mevotech Supreme suspension control arm replaces it. Have the cause diagnosed first, since those symptoms can have other sources.
