How Many Kilometers Should a Truck's Wheel Hubs Be Maintained?
2 Answers
The manufacturer recommends maintenance every 20,000 kilometers. As long as the brakes do not return properly and the vehicle does not slide on slopes, maintenance is required, regardless of the specific mileage. Vehicle inspection items are as follows: 1. Tires: Check tire condition/wear and adjust pressure if necessary; 2. Lights: Inspect the working condition of the lighting system (headlights, indicator lights, emergency signal lights, trunk lights, passenger compartment lights, glove box lights, dashboard warning lights, etc.); 3. Washing Equipment: Check the working condition of the windshield wipers and washing equipment/inspect wiper blade position/wear; 4. Exterior Body: Visually inspect the exterior body, underbody protective components, pipes/hoses (exhaust---fuel lines---brake lines), and the condition of rubber components (dust covers, bushings, spacers, etc.).
As a veteran truck driver with over a decade of experience, I'd say there's no fixed rule for wheel hub maintenance—it all depends on actual usage. The standard practice is to inspect bearings and grease every 50,000 to 70,000 km, but for frequent mountain driving or heavy loads, I recommend advancing it to 30,000 km to prevent severe bearing wear and accidents. Safety comes first—unstable wheel hubs on highways can be dangerous, so make it a habit to check wheel rotation for stiffness or odd noises during car washes. This simple routine saves big money. Pro tip: Always adjust maintenance intervals per actual road conditions, even if they differ from the manual's numbers. Prevention beats cure every time.
