Keep your front suspension located and your steering precise with the Mevotech Supreme control arm and ball joint assembly (CMS901233). This front left lower unit positions the wheel and controls its up-and-down travel, while the integrated ball joint pivots to allow steering and suspension movement. It drops in as a direct-fit replacement for the 2015 Hyundai Sonata, 2016-2021 Hyundai Tucson, 2016-2020 Kia Optima, and 2017-2022 Kia Sportage — see the Buyer's Guide tab for engine-specific coverage.
- Stamped steel construction: built to OE-level tolerances for a dependable factory-style fit.
- Resists corrosion: a protective surface treatment helps prevent rust build-up.
- Premium materials: used across the assembly's components for longer part life.
- Rigorously tested: extensive in-house and third-party durability testing.
Engineered in-house for high-usage passenger vehicles, SUVs, fleets and working trucks, this assembly also uses Labor Saver designs and hardware to make installation faster and easier. If you're shopping a Hyundai Sonata lower control arm or a Kia Optima control arm, worn bushings or a loose ball joint often show up as clunking over the front suspension, uneven tire wear, or wandering steering — if a failed control arm is the cause, this replaces it. Diagnose the cause before replacing.
