We provide precision steer axle reboring and kingpin repair for heavy-duty trucks with worn or out-of-round axle eyes, loose steering components, poor alignment, and premature tire wear.

Using the STEMCO® Axle Pro Equipment™ system, we machine worn axle bores and install case-hardened steel sleeves to restore proper kingpin fit, alignment, and steering performance. The repair is completed with the axle still on the truck, avoiding the cost and downtime of full axle replacement.

In many cases, service can be completed in a single day.

Steer axle rebore services include:

• Kingpin bore inspection
• Worn and out-of-round axle bore correction
• Case-hardened steel sleeve installation
• Kingpin fitment and repair support
• Steering, alignment, and front-end troubleshooting
• Mobile and in-shop service
• Heavy-duty truck and fleet applications

Steer axle reboring can extend the life of kingpins, tires, and suspension components while restoring safer, more dependable handling.

Restore the axle. Reduce downtime. Keep the truck working.
