How to solve the problem of heavy truck trailer axle turning heavy

The heavy steering of a trailer is manifested by the feeling of heaviness and effort when turning the steering wheel, and the lack of a sense of alignment. There are many reasons for this situation to occur, and the reasons we summarize include: deformation of the steering knuckle arm; Lack of oil or damage to the thrust bearing of the steering knuckle; The clearance between the steering knuckle main pin and the bushing is too small or there is a lack of oil; Front wheel misalignment caused by deformation of the front axle or frame; Insufficient tire pressure, etc.

When dealing with the malfunction of the heavy truck trailer axle, first support the front axle and turn the steering wheel. If the steering is relatively easy, it indicates that the malfunction lies in the front axle and wheels. At this point, check if the front tire pressure is too low and if the front axle is deformed; In addition, it is also necessary to consider whether the front steel plate spring is in good condition and whether the frame is deformed. If necessary, check if the wheel alignment angle is correct.
