Keep your front suspension tight and properly located with the Mevotech Supreme control arm and ball joint assembly (CMS501053). This front left (driver's side) lower unit installs as a direct-fit replacement for the 2003-2014 Chevrolet Express 1500 and GMC Savana 1500, plus the 2003-2005 Chevrolet Express 2500 and GMC Savana 2500 — see the Buyer's Guide tab for engine-specific coverage.
The control arm locates the front wheel and pivots as the suspension travels, while the integrated ball joint lets the knuckle move and steer. Clunking over bumps, wandering or loose steering, and uneven front tire wear can be signs a worn Mevotech Supreme lower control arm or ball joint may need replacing — diagnose the cause before installing.
