Keep the front suspension pivoting smoothly and the steering tight with the Delphi Suspension Ball Joint TC2579, a front upper ball joint that links the control arm to the steering knuckle, letting the suspension travel and the wheels steer while carrying load. It installs as a direct-fit replacement for the 1970-1977 Ford Maverick, 1964-1973 Ford Mustang, 1970-1971 Ford Ranchero, 1970 Ford Fairlane, 1970 Ford Falcon, 1970-1971 Ford Torino, 1971-1977 Mercury Comet, 1970-1973 Mercury Cougar, 1970-1971 Mercury Cyclone and 1970-1971 Mercury Montego — see the Buyer's Guide tab for engine-level details.
Built with Delphi's OE expertise, it is tested to withstand temperatures below -40°C and over 120°C plus 720 hours of salt spray. If a worn ball joint is behind clunking over bumps, loose steering or uneven tire wear, this replaces it. Sold individually; front upper joints install as a left/right pair, so order two for a complete replacement.
