Installation Notes and Tips

Installation requires press-in service for the rear upper suspension location. Verify the stud type, mounting dimensions, and vehicle application before installation. Because this part uses a pinch-style stud and does not include a grease fitting, it is intended for standard replacement service rather than routine greasing. Confirm fitment by year, make, model, and rear upper position before ordering.
