Delphi Suspension Ball Joint P/N:TC1641
Keep your suspension tight and your steering precise with the Delphi ball joint TC1607, a front lower suspension ball joint built with Delphi's OE-derived expertise. It's a direct-fit replacement for a wide range of Ford, Lincoln and Mercury models, including the 1979-1993 Ford Mustang and 1986-1997 Ford Aerostar — see the Buyer's Guide tab for the full list.
A front lower ball joint links the lower control arm to the steering knuckle, letting the suspension travel and the wheel steer while carrying load. If a worn joint is behind clunking over bumps, loose steering or uneven tire wear, this replaces it.
Delphi tests to the extreme for OE performance — parts withstand temperatures below -40°C and over 120°C and endure 720 hours of salt spray. Replacing the front lower ball joints on both sides together is recommended.
