Installation Notes and Tips

Verify vehicle fitment by year, make, model, and front left lower position before installation. The threaded, bolt-in design uses a tapered stud and castle nut, and the cotter pin hole is present. Confirm the wrench size is 12 mm and inspect the surrounding control arm and mounting points for wear before assembly. Because this joint is non-greaseable, it is installed as a sealed service component.
