What causes the steering wheel of the Superb to make abnormal noises?

[McGia]

The reasons for abnormal noises when turning the steering wheel of the Superb include steering gear failure, prolonged non-replacement of coupler oil, and insufficient tire pressure. Below are detailed explanations for the aforementioned causes: Steering gear failure: If the steering wheel is frequently turned to its maximum limit during daily driving, it places a greater load on the steering gear, leading to severe wear and resulting in abnormal noises. It is recommended to inspect and replace the relevant components. Prolonged non-replacement of coupler oil: This can easily cause steering bias or vibration. It is advisable to check whether replacement is necessary. Insufficient tire pressure: Uneven tire pressure in the left front or right front tires can cause the front of the car to deviate, leading to unbalanced car bearings and misaligned steering gear, which in turn cause abnormal noises and steering bias.
