Restore secure wheel location and precise steering geometry with the Mevotech Supreme control arm and ball joint assembly (CMS401100) — a front left lower unit that drops in as a direct-fit replacement for the 2012-2018 Ford Focus, 2013-2018 Ford C-MAX, and 2018-2023 Ford Transit Connect. This forged aluminum arm locates the front suspension and pivots on an integrated ball joint that allows the wheel to steer and travel.
Signs the original may need this Ford Focus control arm include clunking over bumps, wandering or loose steering, uneven tire wear, or a torn ball joint boot. Diagnose the cause before ordering, since these signs can have other sources.
