Delphi Suspension Ball Joint P/N:TC1621
Keep your steering tight and predictable with the Delphi ball joint TC9722, a suspension ball joint that pivots the steering knuckle against the control arm so the wheel can steer and travel while the joint carries and locates the load. Delphi applies its OE engineering to its aftermarket steering portfolio, and this joint reflects that program. See the Buyer's Guide tab for the vehicles and engines this part fits.
Delphi tests to the extreme for OE performance: parts withstand temperatures below -40°C and over 120°C and are exposed to 720 hours of salt spray, and extensive dimensional and material analysis is done to match the OE and aftermarket part. A worn ball joint may show up as clunking, loose or wandering steering, or uneven tire wear.
