There will be some problems in the use of trailer axle, such as heavy steering. In this case, we should find out the reasons first, and then deal with them accordingly. Now we will analyze the heavy steering problem of trailer axle.


The heavy steering of the trailer is mainly manifested by the heavy and laborious feeling of turning the steering wheel, and there is no sense of return. There are many reasons for this phenomenon, we summarize the reasons are: steering knuckle arm deformation; The thrust bearing of steering knuckle is short of oil or damaged; The clearance between steering knuckle kingpin and bushing is too small or lack of oil; Front axle or frame deformation causes front wheel alignment misalignment; Insufficient tire pressure, etc.


In view of the fault of the trailer axle, first support the front axle and turn the steering wheel. If the steering is easy, it means that the fault lies in the front axle and wheels. At this time, check whether the front tire pressure is too low and whether the front axle is deformed; At the same time, check whether the front leaf spring is in good condition and whether the frame is deformed. If necessary, check that the wheel alignment angle is correct.
