Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS80105
Keep your rear suspension located and pivoting freely with the Mevotech Supreme control arm and ball joint assembly (CMS90172), a rear lower unit that installs as a direct-fit replacement for the 1998-2005 Hyundai Sonata, 2001 Hyundai XG300, 2002-2005 Hyundai XG350, 2001-2006 Kia Optima and 2001-2006 Kia Magentis. It combines the rear lower control arm, its bushings and an integrated ball joint into one serviceable assembly that connects the knuckle to the chassis and lets it pivot through suspension travel.
If a worn arm or ball joint is behind clunking over bumps, loose or wandering handling, or uneven rear tire wear, this Hyundai Sonata control arm replacement gives you a fresh pivot and mounting point. It's also a fitting Kia Optima control arm swap for the applications listed above.
