Axle & Bearing Repair
Expert axle and wheel bearing services to prevent costly breakdowns.
Wheel bearings and axle components take tremendous abuse on long hauls. We specialize in diagnosing and repairing axle issues before they become major problems. From bearing replacement to complete axle rebuilds, we keep your truck rolling smoothly.
Wheel bearings, hub assemblies, and axle components endure enormous stress on every mile of highway. A failing wheel bearing that goes undetected during a pre-trip inspection can seize at highway speed, causing a wheel-off event that endangers the driver and everyone on the road. Weldon's Truck & Trailer provides expert axle and bearing repair for Class 8 semi trucks and trailers from our Kingman, AZ base, with mobile service across a 200-mile radius covering I-40, US-93, and surrounding highways. Our ASE certified diesel mechanics diagnose and repair steer axle, drive axle, and tandem axle assemblies on all major truck brands. Whether you need a single wheel bearing replacement on the shoulder of I-40 or a complete hub assembly rebuild at your terminal, our technicians arrive equipped to get the job done right.
Detailed Axle & Bearing Services
Our axle and bearing services cover the complete wheel end and drivetrain system on commercial vehicles. We replace wheel bearings and wheel seals on both oil bath hub and grease-packed hub designs, as well as pre-adjusted bearing and unitized hub assembly configurations, packing and adjusting bearings to manufacturer specifications. Our technicians inspect hub cap condition and hub oil level on oil bath hubs, and replace spindle nuts, lock washers, and bearing races to ensure proper preload and endplay. For drive axle work, we service the differential assembly including ring and pinion gear sets, carrier bearings, and limited-slip clutch packs. We replace U-joints, driveshaft assemblies, and yoke connections when vibration or driveline wear is detected. We service steer axle, drive axle, tandem axle, tag axle, and pusher axle configurations on all major truck brands. Steer axle king pin replacement, axle shaft service, tie rod end replacement, and steering gear adjustments are also part of our capabilities for maintaining safe vehicle handling and DOT compliance during CDL pre-trip inspections.
What's Included
Common Axle & Bearing Problems We Fix
The most common bearing failures we encounter are caused by contaminated lubricant—a failed wheel seal allows dirt and moisture into the bearing race, causing pitting and eventual seizure. Overheated bearings from improper adjustment or low oil levels in oil bath hubs are another frequent issue, often detected by a hot hub during a pre-trip inspection or by a driver smelling burning grease. Drive axle problems typically involve worn U-joints that cause driveshaft vibration, leaking pinion seals, and differential noise from worn ring and pinion gears. On tandem axle setups, inter-axle differential failures and power divider lockout issues are common. Our technicians carry the bearing kits, seals, and diagnostic tools needed to handle these repairs on-site.

We stock common bearing kits, wheel seals, and hub components on our service trucks for fast on-site repairs. Every bearing job includes a complete wheel-end inspection to catch secondary issues before they cause another breakdown.
