Keep the rear suspension located and the ride controlled with the Mevotech Supreme Lateral Arm and Ball Joint Assembly, CMS90124. It drops in as a direct-fit replacement for the 2007-2012 Hyundai Elantra, combining the lateral arm and its integrated ball joint into one rear lower forward assembly. See the Buyer's Guide tab for the full engine-level fitment.
This arm helps position the wheel and maintain proper suspension geometry, while the ball joint provides the pivoting connection that lets the wheel move through its travel. If a worn lateral arm or ball joint is the cause of clunks, uneven tire wear, or a loose feel over bumps, this assembly replaces both in a single part.
Because these parts install as left/right pairs, inspect the opposite side and replace as needed for balanced handling.
