The cost for a kit containing bushings and kingpins can range from $500 to $1,500 and replacing them is very time consuming. However, the kingpins and tie rods can wear out extremely fast if they’re not greased on a regular basis. Nothing lasts forever, even if these parts have been greased every day. “Kingpins and bushing replacement are rarely covered under warranty, because it always relates to lack of preventive maintenance.” The good news is the kingpins have a life of 750,000 miles, so with good maintenance they would only need to be replaced once during a truck’s lifetime,” said Duane Rasmussen, Instructor, Medium/Heavy Truck Technology, Hennepin Technical College. “It’s an 8-hour job to ream the bushing and replace the kingpin. Use a dial indicator to measure, axial and lateral movement should not exceed 1/8 or. If the wheel has any play you may have an issue likely caused by a worn kingpin.

An easy way to help determine a worn kingpin is to conduct a kingpin wear inspection.īefore beginning, make sure to always review and follow the axle manufacture and company maintenance and procedure manuals. Because of the potential for further damage and operator safety risks, properly diagnosing and repairing worn kingpins, bushings and tie rods needs to be addressed promptly.Īfter experiencing symptoms of a kingpin and bushing failure, additional diagnoses must be done to rule out other wheel assembly issues that may also cause similar symptoms. Experiencing these symptoms while driving may result in a shaking cab or steering wheel. You will notice signs of kingpin and bushing failure from incorrect vehicle alignment, premature and uneven front tire wear, and rough handling. They are available in both front and rear kits, and come in single, 2, 3, 4, 6 and 8-piston configurations.Improper lubrication of kingpin bushings can cause kingpin contact points to begin to wear at the steering knuckle.
