Installation Notes and Tips

Installation of the Delphi TC1678 ball joint requires pressing the unit into the control arm or suspension component. Ensure the mounting surface is clean and free of debris before installation.

Note that this ball joint does not include a grease fitting and is not greaseable, so periodic inspection is recommended. Castle nuts, cotter pins, and bushings are not included and should be sourced separately if required.
