Keep your front-end geometry tight and your wheel located precisely with the Mevotech Supreme control arm and ball joint assembly (CMS101388), a front left upper unit that drops in as a direct-fit replacement for a wide range of listed Mercedes-Benz models. It combines the control arm and ball joint into one part, positioning the wheel while letting the suspension move through its travel.
- Forged aluminum construction: built to OE-level tolerances for durability under high-usage commercial, fleet, and passenger-vehicle duty.
- Corrosion-resistant ball joint: additional surface treatment resists rust build-up for longer ball joint life.
- Faster fit: includes a part-specific locking nut to speed up ball joint installation, part of Mevotech's Labor Saver design.
- Rigorously tested: validated through in-house and third-party durability testing.
As a Mevotech Supreme suspension control arm, it serves the front left upper position on the listed vehicles. Worn control-arm bushings or a failing ball joint can show up as clunking over the front end, loose or wandering steering, and uneven tire wear; if the original arm or its ball joint is the cause, this assembly replaces both in one part. Diagnose the cause before replacing.
