Each and every part on your vehicle is important (except maybe the flap that covers over the DC outlet under your radio), and it's your responsibility as a proud automobile owner to replace worn out gear with proper new parts, including the steering rack & pinion lock nut. As it happens, AutoAnything has a lot of steering rack & pinion lock nuts laying around, and we would love to send you as many as you need. We will even give you free shipping and a 1-year lower-price guarantee on every steering rack & pinion lock nut that you order.
