Keep your front suspension tight and steering precise with the Delphi ball joint (MPN TC6494), a front lower suspension ball joint built with Delphi's OE-derived expertise. It drops in as a direct-fit replacement for the listed applications, including the 1965-1969 Cadillac Calais, 1961-1969 Cadillac DeVille, 1963-1970 Oldsmobile 98, 1965-1970 Oldsmobile Delta 88 and 1968-1982 Checker Marathon — see the Buyer's Guide tab for the full list of Cadillac, Oldsmobile and Checker models.
A ball joint pivots the steering knuckle against the control arm, carrying suspension load while allowing the wheel to steer and travel. Worn joints can produce clunking on acceleration or bumps, loose steering and uneven tire wear — signs this part may need replacing.
