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 on many vehicles, among them the 1964-1973 Ford Mustang, 1970-1977 Ford Maverick and 1970-1971 Ford Ranchero — see the "Vehicles it fits" section for the full list and engine-level details.
- Forged for strength: made from high-quality forgings for increased strength and smooth operation.
- Chloroprene rubber boot: improves durability and helps prevent premature failure.
- Micron-tolerance machining: machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics.
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, and replacing both sides together is recommended.
