Inside a Kingpin Repair: Bushings, Bearings & Shims Explained

A bad kingpin can lead to uneven tire wear, worn bearings and bushings, and much more expensive repairs if the problem is ignored. In this video, TSP mechanic Rafael walks us through a complete kingpin repair, explaining what causes kingpins to wear, how to identify excessive play, what the bushings and bearings do, and how the components are replaced and properly fitted. You'll see the repair process from removing the old bushings and installing new ones to reaming the bushings, installing the seals, setting the shims, and securing the kingpin. Rafael also explains some of the warning signs drivers should pay attention to and why regular greasing and maintenance are critical. If you're a truck driver, owner-operator, or simply interested in how heavy-duty trucks are maintained, this is a good look inside the repair process.
