More Information About Axle Boring

Axle Boring Service in Ohio

The steer axle kingpin is the pivot point between the axle beam and the wheel ends. The kingpin is also the point of connection for the spindle knuckle, the wheel ends, and the steer axle. The role of the steer axle kingpin is to maintain steering geometry on the vehicle as it provides the ability for the wheel ends to turn the vehicle left or right.

As such an important component, preventative and ongoing maintenance for the steer axle kingpin is something that should not be neglected. Even with rigorous preventative maintenance and lubrication, there may come a time when you need to replace your kingpin and you may also experience wear on your axle eye. 

Fortunately, if you are replacing kingpins, even if the axle eyelet is worn out, The Service Company can help you not have to replace the entire axle. We offer bore/bush service on your axles at all 3 of our locations.  Our state-of-the-art axle boring machine provides an affordable, simple and quick way to enhance worn axle eyes with case hardened sleeves that bring your axle back to new.
