What Causes Steering Wheel Vibration at Idle Speed?
1 Answers
The causes of steering wheel vibration at idle speed are: 1. If the vibration amplitude is not significant, it is generally caused by resonance, which has little impact on vehicle usage. It is necessary to check whether there are issues with the rubber bushings of the steering wheel transmission device or if the bolts securing the steering wheel transmission device are loose. 2. Unstable oil pressure. If the fuel pump's supply pressure is abnormal or the intake pressure sensor's readings are incorrect or malfunctioning, it can cause body vibration. The solution is to check the oil pressure and replace components if necessary. 3. Check whether the steering wheel vibration is related to the engine idle speed or the steering gear. Vibration may also occur when the steering wheel is turned to its limit, sometimes accompanied by abnormal noises, mostly due to steering gear pressure relief or air resistance in the power steering fluid.
