What are the reasons for abnormal noise when turning the Mercedes-Benz steering wheel?

[DeAriana]

The reasons for abnormal noise when turning the Mercedes-Benz steering wheel are lack of lubricating oil in the screws, steering gear failure, and insufficient tire pressure. Lack of lubricating oil in the screws: If there is a lack of lubricating oil in the screws inside the steering wheel, the steering wheel cover needs to be removed to add lubricating oil. This should make the track and rotating shaft smooth. Steering gear failure: The steering gear may also fail. Usually, if the steering is turned too fully during operation, it places a greater load on the steering gear, leading to severe wear and resulting in abnormal noise. It is recommended to inspect and replace the components. Insufficient tire pressure: Insufficient tire pressure or uneven pressure in the left front or right front tires can cause the front of the car to deviate, leading to unbalanced car bearings, misaligned steering gear, and resulting in abnormal noise and deviation.
