Delphi Suspension Ball Joint P/N:TC1621
Keep your steering and suspension precise and controlled with the Delphi ball joint TC7870, a suspension ball joint built with the same OE safety technology Delphi fits to millions of vehicles worldwide. A ball joint links the control arm to the steering knuckle, letting the suspension travel up and down while the wheel pivots to steer — when it wears out, that connection develops play. See the Buyer's Guide tab for the full list of compatible vehicles.
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, with extensive dimensional and material analysis to match OE and aftermarket fit. If a worn ball joint is the cause of clunking over bumps, wandering steering, or uneven tire wear, this replaces it.

What does a ball joint do?
It connects the control arm to the steering knuckle, allowing the suspension to move up and down while the wheel pivots to steer. As it wears, the joint develops play that affects steering and handling.
What are the signs my ball joint may need replacing?
Common signs include clunking or knocking over bumps, wandering or loose steering, and uneven tire wear. Diagnose the cause before replacing, since these symptoms can have other sources.
What is the boot on this Delphi ball joint made of?
It uses a chloroprene rubber boot, which improves durability and helps prevent premature failure by keeping contaminants out of the joint.
