Keep your BMW's front suspension tight and properly located with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly / Lateral Link, MPN CMS101250. This is the front left lower unit, engineered in-house with application-specific upgrades and installed as a direct-fit replacement on the 2011-2017 BMW X3 and the 2015-2018 BMW X4 (see the "Vehicles it fits" section for engine-level fitment). The control arm locates the wheel and works with its integrated ball joint to allow steering and suspension travel; worn arm bushings or a loose ball joint can bring on clunks over bumps, wandering steering, and uneven tire wear.
