What Causes Slight Abnormal Noise When Turning the Steering Wheel?

[McAdelyn]

Below are the possible locations and causes of abnormal noise when turning the steering wheel: 1. Noise from inside the steering wheel: If the noise comes from inside the steering wheel, the issue is most likely caused by the clock spring (spiral cable) for the airbag. Remove the steering wheel and apply some grease to the clock spring to see if the noise persists. If it still occurs, replace the clock spring as it may be damaged. Be gentle when removing the steering wheel, or disconnect the airbag fuse to prevent accidental deployment. 2. Noise from the strut mount bearing: If the noise originates outside the vehicle, it might be due to insufficient lubrication in the strut mount bearing. Open the hood and listen to determine if the noise comes from the top of the strut mount. If confirmed, apply grease to the bearing. If the noise continues, replacement is necessary. 3. Noise from the stabilizer bar: If the noise is not from the strut, check if the stabilizer bar bushings are loose or damaged. Loose or damaged bushings can cause noise not only when turning the steering wheel but also when driving on uneven roads. Loose bushings can be fixed by adding shims, but damaged ones must be replaced.
