Durable Construction and Design Details
The Delphi TC1684 suspension ball joint features a 1.752 inch (44.5 mm) maximum outside diameter and a length of 83 mm, designed to meet OEM specifications for the Toyota Tercel. The ball joint assembly comes with a non-threaded stud type and a stud thread length of 83 mm, ensuring proper fitment and function.

The included mounting hardware simplifies the process, but professional installation is recommended to ensure proper torque and alignment. The grease fitting allows for periodic lubrication, which helps maintain smooth operation and extends the service life of the ball joint. Note that this part does not include a castle nut or cotter pin, so verify if your vehicle requires these components separately.
