What It Helps Fix

• Front-end looseness or play from a worn upper ball joint

Installation Notes and Tips

Install this part only on the listed front upper applications for Ford Ranger and Mazda B-series trucks. Verify the control arm style before ordering, since several fitments are specified for aftermarket control arms with replaceable ball joints. The press-in, threaded design and tapered stud should be matched to the correct suspension setup, and the included castle nut and mounting hardware should be used during installation. Always confirm vehicle year, make, model, and suspension configuration before service.
