Restore precise wheel location and quiet, stable handling with the Mevotech Supreme control arm CMS901209, a rear upper control arm and ball joint assembly that drops in as a direct-fit replacement for the 2003-2006 Hyundai Santa Fe (see the Buyer's Guide tab for engine-level fitment). Engineered in-house with application-specific upgrades, this Mevotech Supreme suspension control arm is built for high-usage passenger, SUV and fleet duty.
The rear upper control arm locates the wheel and, through its integrated ball joint, lets the suspension travel while helping hold alignment. If a worn control arm or ball joint is the cause of clunking over bumps, loose or wandering steering, or uneven tire wear, replacing this assembly restores those components.
