· Measure if the tire pressure is normal. If necessary, inflate it according to the specified · Check if there is leakage in the oil tube connectors of the steering hydraulic steering system. If there is leakage, screw them tightly. Inspect if there is damage, deformation or crack on · Check the rotation movement of the steering rack & pinion mechanism at the wheel return · Check if the steering control valve is blocked or returned improperly.

Vibration of the steering wheel as turning ※Malfunction symptom As the engine works, turn the steering wheel. It vibrates, especially at the limit position. ※Malfunction reason · The steering oil pump driving-belt slides. · The oil level is too low in the oil reservoir. · The air enters the steering hydraulic loop · The output pressure of the steering oil pump is insufficient. · The piston of the pressure regulator in the steering oil pump is blocked. ※Diagnosis and Troubleshooting · Check if the steering oil pump driving-belt is sliding or damaged. If necessary, tighten the · Check if the oil level of the oil reservoir reaches the specified value. If necessary, fill with · Check all the connectors of the steering hydraulic system to see if there is leakage of the · Check the output pressure of the steering oil pump. Disassemble the pump when the pressure is insufficient to determine if there is wear or serious internal leakage of the oil |
