Keep the front-left wheel located and steering crisp with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly (CMS901301) — a front left lower MEVOTECH control arm that installs as a direct-fit replacement for the 2021-2025 Hyundai Elantra. This control arm and ball joint assembly locates the wheel to the chassis while its integrated ball joint lets the steering knuckle pivot through steering and suspension travel, so a worn original that clunks, wanders, or wears tires unevenly can be swapped as one unit.
Engineered in-house with application-specific upgrades, Mevotech Supreme parts are built for high-usage passenger vehicles, SUVs, fleets and working trucks, and Labor Saver designs help make the job faster. If a failed lower control arm or ball joint is behind your handling issue, this MEVOTECH lower control arm — a Hyundai Elantra control arm for the front left lower position — replaces it.
