Common Repair Symptoms

Installation Notes

Confirm the vehicle is a 2017-2020 Ford F-150 with the front upper ball joint application before installation. Because this is a press-in design, proper suspension service tools are required for removal and installation. Inspect the mating control arm and surrounding hardware for wear, and verify torque specifications during reassembly. The included grease fitting allows future lubrication service after installation.
