Keep the front wheel precisely located and the steering geometry true with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly (CMS861331), a direct-fit front right lower Toyota Sienna control arm that installs as one complete unit. It fits the 2021-2025 Toyota Sienna, 2023-2025 Lexus RX350 and RX350H, 2024 Lexus RX450H+ and RX500H, and 2024-2025 Lexus TX350, TX500H, and TX550H+.
Part of the Mevotech Supreme line, this control arm and ball joint assembly is engineered in-house with application-specific upgrades and built for high-usage passenger vehicles, SUVs, fleets and working trucks.
The lower control arm locates the front wheel and hinges the suspension while the integrated ball joint links the arm to the steering knuckle. Clunking over bumps, wandering steering, or uneven front tire wear can be signs a worn control arm or ball joint may need replacing. If a failed arm or joint is the cause, this Mevotech Supreme suspension control arm replaces them.
