What Causes the Abnormal Noise When Turning the Steering Wheel to Full Lock?
1 Answers
An abnormal noise when turning the steering wheel to full lock could be due to a faulty plane bearing under the steering wheel. It might also be caused by a loose tie rod end ball joint. During steering, the front suspension system undergoes continuous changes in force, accumulating internal stress. When the steering reaches a certain point, the increased stress causes an instantaneous displacement at the loose ball joint, resulting in vibration and abnormal noise. Here are more details: Continuous friction sound when turning the steering wheel: This noise is likely due to a damaged plane bearing under the steering wheel. The plane bearing, also known as the pressure bearing, is located at the top of the front shock absorber where it connects to the vehicle body. Its function is to allow the shock absorber to rotate with the wheels during steering. If this abnormal noise occurs, it should be inspected and repaired promptly; otherwise, it may eventually prevent the steering wheel from turning. Abnormal noise when the steering wheel is turned to a certain point: This situation is likely caused by a loose tie rod end ball joint. During steering, the front suspension system experiences continuous changes in force, accumulating internal stress. When the steering reaches a certain point, the increased stress causes an instantaneous displacement at the loose ball joint, resulting in vibration and abnormal noise. At low speeds or when stationary, the steering and suspension systems bear the maximum force during steering. When the steering angle increases to a certain point, this stress causes the loose part to slide, generating vibration.
