Installation Notes and Tips

Compatible With front lower suspension positions only on the listed vehicles. Verify year, make, model, and position before installation. The press-in, threaded design requires proper suspension service tools and correct torque procedures. The tapered stud uses a 12 mm wrench size, and the cotter pin hole allows secure final assembly where specified by the vehicle application.

Because this is a greaseable ball joint, follow the vehicle service schedule and lubrication requirements after installation. The included dust boot helps protect the joint from contamination during severe-duty operation.
