Keep your front suspension tight and tracking straight with the Mevotech Supreme control arm CMS101438, a front left (driver-side) lower control arm and ball joint assembly that drops in as a direct-fit replacement for the 2001-2006 BMW M3. See the Buyer's Guide tab to confirm your exact engine.
This front left lower arm locates the wheel and holds the correct suspension geometry, while its integrated ball joint allows the steering and suspension to move together. Clunking over bumps, loose or wandering steering, and uneven front tire wear can be signs the control arm bushing or ball joint is worn — diagnose the cause before replacing. Whether you searched for a Mevotech Supreme lower control arm, a Mevotech Supreme suspension control arm, or simply a Bmw M3 control arm, CMS101438 is the front left lower unit.
