How to solve heavy truck trailer axle steering heavy
Author:
The heavy steering of the trailer is specifically manifested in the heavy and laborious turning of the steering wheel, and there is no sense of returning to the right. There are many reasons why this happens, and the reasons we summarize are: deformation of the steering knuckle arm; lack of oil or damage to the thrust bearing of the steering knuckle; too small clearance or lack of oil between the kingpin of the steering knuckle and the bushing; deformation of the front axle or frame Causes misalignment of front wheels; insufficient tire pressure, etc.
When dealing with heavy-duty truck trailer axle failures, first support the front axle and turn the steering wheel. If the steering is easier, it means that the fault lies in the front axle and wheels. At this time, you should check whether the front tire pressure is too low and whether the front axle is deformed; in addition, 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.
