Mevotech Supreme Suspension Ball Joint P/N:MS10501
Silence front-end clunks and keep your steering tight with the Mevotech Supreme Suspension Ball Joint (MK8142) — a direct-fit Mustang ball joint for the FRONT UPPER position on classic Ford and Mercury applications. It fits the 1965-1973 Ford Mustang, 1970-1977 Ford Maverick, 1962-1970 Ford Fairlane, 1963-1970 Ford Falcon, 1963-1971 Ford Ranchero, 1968-1971 Ford Torino, 1963-1977 Mercury Comet, 1967-1973 Mercury Cougar, and 1968-1971 Mercury Montego — see the Buyer's Guide tab for the full list.
As the front upper pivot, this suspension ball joint links the control arm to the steering knuckle, letting the suspension travel while the wheels steer. Worn joints can cause knocking over bumps, wandering steering, and uneven front tire wear — if a failed upper ball joint is the cause, this replaces it.
Whether you're chasing down a worn Ford Maverick ball joint or refreshing the front end on an early Mustang, this is a straightforward replacement.
