Kingpin is the part that is the main pivot point in the steering system. In general, kingpins have a lifespan of about 750,000 miles.

Our Kit includes everything you need for replacement including bearing. Our King Pin kit is a European quality repair kit with 1 year warranty. How do I know if I have a worn king pin? Improper lubrication of king pin bushings can cause king pin contact points to start to wear at the steering knuckle. You will notice signs of king pin and bushing failure from incorrect vehicle alignment, premature and uneven front tire wear, and rough handling. Experiencing these symptoms while driving may result in a shaking cab or steering wheel. Because of the potential for further damage and operator safety risks, properly diagnosing and repairing worn king pins, bushings and tie rods needs to be addressed promptly. If you are experiencing symptoms of a king pin and bushing failure, additional inspection must be done to rule out other wheel assembly issues that may cause similar symptoms. An easy way to help determine a worn king pin is to conduct a king pin wear inspection.
