What It Helps Address

  • Uneven tire wear related to suspension wear

  • Grease retention issues in serviceable joint applications

Installation Notes and Tips

Confirm axle and stud design before ordering, since listed fitment includes Dana 28 axle and threaded stud configurations on several Ford applications. This is a press-in ball joint, so proper removal and installation tools are recommended for the front upper suspension service. After installation, grease the joint through the service fitting and verify cotter pin alignment at the castle nut.
