Keep your steering tight and front suspension moving smoothly with the Delphi ball joint TC5399, a front upper Suspension Ball Joint that connects the control arm to the steering knuckle and pivots as the wheel steers and the suspension travels. This front upper Custom ball joint drops onto vintage Ford, Edsel, Lincoln and Mercury applications — including the 1957 and 1964-1972 Ford Custom, 1971-1980 Ford Pinto, 1974-1978 Ford Mustang II, 1958-1979 Ford Thunderbird, 1970-1979 Lincoln Continental and 1957-1974 Mercury Monterey. See the Buyer's Guide tab for the full list of 51 applications.

Built on Delphi's OE steering expertise, this part is tested to the extreme — withstanding temperatures below -40°C and over 120°C and enduring 720 hours of salt spray, with extensive dimensional and material analysis for close compatibility with the OE part. If a worn front upper ball joint is the cause of clunking, loose steering, or uneven tire wear, this direct-fit replacement addresses it. Sold individually.
