Why is there a noise when turning the steering wheel?
1 Answers
Noise during steering wheel rotation can be attributed to the following faults: 1. Continuous friction sound when turning the steering wheel: This noise is likely caused by a faulty plane bearing (also called pressure bearing) located beneath the steering wheel. The plane bearing is positioned at the connection point between the top of the front shock absorber and the vehicle body. Its function is to facilitate rotation between the shock absorber (which turns with the wheel) and the vehicle body during steering. This abnormal noise requires prompt inspection and repair, as it may eventually prevent the steering wheel from turning. 2. Noise occurring when the steering wheel is turned to a certain degree: This situation is probably due to a loose stabilizer link ball joint. During steering, the front suspension system undergoes continuous force changes and internal stress accumulation. When steering reaches a certain point, the increased stress causes instantaneous displacement at the loose ball joint, resulting in vibration and noise. When turning at low speeds or while stationary, the steering and suspension systems bear maximum stress. As the steering angle increases, this stress causes slippage at loose components, generating vibrations. 3. Steering wheel vibration during idle driving: Normally, the steering wheel shouldn't vibrate during idle operation - even minor vibrations indicate no significant issues. However, pronounced vibration likely suggests problems with the steering wheel transmission device or loose bolts securing this mechanism. 4. Failure to automatically return after a steering wheel noise: This condition strongly indicates a faulty or aged steering gear, requiring immediate inspection and replacement.
