What It Helps Address

Installation Notes and Tips

Verify fitment by year, make, model, and front lower position before installation. Press-in ball joints require proper removal and installation tools to avoid damage to the control arm or knuckle. Confirm the tapered stud, castle nut, and cotter pin hole alignment during assembly, and inspect related suspension components for wear while the joint is apart.
