Keep your classic Ford's front suspension tight and tracking straight with the Mevotech Supreme control arm and ball joint assembly, part number CMK8121. This front lower unit is a direct-fit replacement for the 1966-1967 Ford Falcon, 1967 Ford Mustang and 1966 Ford Ranchero — see the Buyer's Guide tab to confirm the engine for your vehicle. As a complete control arm and ball joint assembly, it locates the lower end of the front knuckle while the integrated ball joint pivots to allow steering and suspension travel.
Clunking or knocking from the front suspension, loose or wandering steering, and uneven front tire wear can be signs the control arm bushing or ball joint may need replacing; diagnose the cause before ordering. If a worn lower arm is the cause, this bolt-in assembly replaces it and reconnects to the factory mounting points.
