King Pin Repair & Replacement

At Harry J. Smith Co., we offer a complete range of king pin replacement, king pin servicing, and king pin repair services.

Failure of the king pin means that the steering system will not work properly, and improperly working steering systems can be dangerous. To avoid accidents arising from turning problems make sure your truck’s king pin is regularly checked and serviced. King pins and tie rods can wear out extremely fast if they’re not greased on a regular basis.

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’ll 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’re 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.
