Keep steering tight and suspension movement controlled with the Delphi ball joint TC437, a front lower suspension ball joint that connects the control arm to the steering knuckle and lets the wheel pivot for steering while the suspension travels. It drops in as a direct-fit replacement for the 1986-1990 Acura Legend, 1987-1988 Sterling 825, and 1989-1991 Sterling 827 — a proper Acura Legend ball joint for the listed applications.
Signs this part may need replacing include clunking over the front suspension on acceleration or braking, wandering steering, and uneven tire wear. If a worn front lower ball joint is the cause, this replaces it.
