Heavy Truck Repair

Heavy truck workshops fit tapered roller bearings in differentials, pinion positions and wheel ends, along with clutch release bearings in the driveline. These bearings run under high payloads, repeated braking loads and road contamination. Workshops need the correct cone and cup pairing, plus reliable setting during reassembly, to avoid repeat failures.

• Replace wheel-end cones and cups as confirmed pairs, and check the cup seat for wear before fitting.
• Confirm the differential and pinion bearing numbers against the axle model, since these positions often use inch series.
• Follow the axle maker's endplay or preload setting after installation to prevent early heat damage.
• Include the truck and axle model in the request when old bearing markings are incomplete.
