Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS101077
Tighten up worn steering and get your front suspension geometry back in line with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly (CMS861155) — a direct-fit Toyota Corolla control arm for the 2014-2022 Toyota Corolla. It replaces the front left (driver-side) lower control arm with the ball joint pre-installed, so it locates the wheel, allows suspension travel, and lets the wheel steer and articulate through the integrated ball joint. Mevotech Supreme parts are engineered in-house with application-specific upgrades and built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks.
Sold individually as the front left lower unit; the opposite side is a separate part. If worn control-arm bushings or a loose ball joint are behind clunking over bumps, wandering steering or uneven tire wear, this assembly replaces them.
