How often should four-wheel maintenance be performed on a 4.2-meter truck?
2 Answers
Trucks require four-wheel maintenance every 30,000 kilometers. The main items of four-wheel maintenance include four-wheel alignment, dynamic balance testing, checking tire pressure, and inspecting tire wear conditions. Regular four-wheel maintenance can enhance driving safety and reduce abnormal tire wear. Four-wheel maintenance primarily focuses on the vehicle's hub components, with the following details: 1. Cleaning: During normal driving, dust, water, and other debris may seep into the hub bearings, which need to be cleaned out. 2. Adjustment: After a period of use, the four-wheel bearings of the vehicle will experience wear, causing changes in the overall clearance. Tightness adjustments are necessary to prevent excessive clearance, which could lead to tire deviation during driving. 3. Lubrication: Bearings require grease for lubrication. Due to the effects of temperature, dust, and moisture, the performance of the grease may degrade, failing to provide adequate lubrication. Therefore, regular lubrication is essential. 4. Replacement: All components wear out, and bearings are no exception. Once they reach the end of their service life, they need to be replaced.
For commonly used light trucks like the 4.2-meter cargo vehicles, I recommend that the wheel maintenance interval primarily depends on mileage. Generally speaking, for those that are driven more frequently, such as long-distance transport or delivery vehicles, a comprehensive inspection should be conducted every 5,000 to 8,000 kilometers. This includes checking tire wear, brake pad thickness, and the condition of bearing lubricants. Having driven this type of vehicle for many years, I've noticed that poor road conditions, like frequent travel on dirt roads or highways, can accelerate wear, necessitating an earlier inspection around 4,000 kilometers. I also regularly monitor the tread depth of the tires; if it's less than 1.6 millimeters, they should be replaced promptly to avoid the high risk of blowouts at high speeds. In short, don't rely solely on mileage—consider actual usage habits and inspection indicators to save a lot of maintenance trouble and extend the vehicle's lifespan.
