Installation Notes and Tips

Verify the vehicle uses the front upper, 4-bolt configuration before ordering. Inspect the control arm, fasteners, and surrounding suspension components for wear during installation. Because this joint is non-greaseable and non-adjustable, proper fitment and correct torque are important for long-term service. Confirm the tapered stud and cotter pin alignment during assembly.
