It is accepted by many large transport companies because of its large capacity and high efficiency. However, when the three axle trailer runs about 30000 km, the abnormal tire wear occurs in varying degrees. With the increase of vehicle mileage, the wheelbase deviation of some axles will change
(1) The U-bolt is loose;
(2) The axle assembly is deformed when driving under abnormal conditions;
(3) The suspension guide is damaged. Because the vehicle in the process of driving, uneven road, sharp turns and other reasons, especially the rubber sleeve of the guide rod is easy to damage.
