Keep the front wheel precisely located and the steering pivot smooth with the Mevotech Supreme Suspension Control Arm and Ball Joint Assembly CMS86135 — the front right upper unit many owners search for as Tundra upper control arms. It installs as a direct-fit replacement for the 2007-2021 Toyota Tundra and 2008-2022 Toyota Sequoia, locating the front right upper corner while its integrated ball joint lets the knuckle pivot through steering and suspension travel.
This is a complete control arm and ball joint assembly, so worn bushings and a loose ball joint are addressed together in one part. If a clunk over bumps, popping in turns, loose steering, or uneven front tire wear traces back to the front right upper arm or its ball joint, this assembly replaces those worn pivot points. Sold individually as the front right upper corner; the left side uses a separate part.
