Bring the front suspension back to spec with the Mevotech Supreme control arm, part number CMS501143 — a front right lower control arm and ball joint assembly that installs as a direct-fit replacement on the 2006-2010 HUMMER H3 and the 2009-2010 HUMMER H3T. It locates the wheel and hub, controls up-and-down suspension travel, and its integrated ball joint lets the steering knuckle pivot.
Worn control-arm bushings or a loose ball joint can show up as clunking over bumps, a wandering steering feel, or uneven front tire wear; if a failed front right lower arm is the cause, this assembly replaces it. Sold individually as the front right lower unit for the listed Hummer H3 applications.
