What Causes Steering Wheel Noise in Cars?

[VanEmily]

Causes of steering wheel noise in cars: 1. Friction between plastic components: The steering wheel consists of various plastic parts, and if the gaps are too small, abnormal noises may occur; 2. Interference from the airbag spring: If the sound comes from inside the steering wheel, remove the steering wheel and apply some grease to the airbag clock spring. If the noise persists, the airbag clock spring needs to be replaced; 3. Noise from the shock absorber plane bearing: Open the hood and listen to see if the sound is coming from the top of the shock absorber. If it's the shock absorber plane bearing making noise, apply some grease to it. If the noise continues after greasing, the bearing needs to be replaced; 4. Improper tension or aging of the power steering belt: For mechanical and hydraulic power steering systems, if the belt is not properly tensioned or has aged, abnormal noises will be heard. Adjust the belt tension or replace the belt as needed.
