Keep the rear suspension pivoting smoothly and securely with the Delphi ball joint TC350, a rear lower suspension ball joint that draws on Delphi's OE steering and suspension experience. It drops in as a direct-fit replacement for the 1985-1987 Audi 4000 Quattro, 1988-1989 Audi 80, 1988-1989 Audi 80 Quattro, 1988-1989 Audi 90, 1988-1989 Audi 90 Quattro, and 1983-1986 Audi Quattro — see the Buyer's Guide tab for engine-level detail.
A ball joint locates and pivots the suspension, letting the wheel move up, down, and steer while carrying load. When the joint wears, look for clunking on acceleration or over bumps, loose or wandering steering, and uneven tire wear as signs it may need replacing.
Delphi tests to OE performance extremes, from below -40°C to over 120°C, with 720 hours of salt-spray exposure and extensive dimensional and material analysis.
