What Causes the Abnormal Noise Under the Car When Turning the Steering Wheel?

[McLane]

Here are the specific reasons for abnormal noise under the car when turning the steering wheel: 1. Faulty airbag clock spring: If the noise comes from inside the steering wheel, it may be caused by interference from the airbag clock spring inside the steering wheel. 2. Lack of oil in the shock absorber plane bearing: When turning the steering wheel, if the abnormal noise comes from outside the car, it may be due to the shock absorber's plane bearing lacking oil. If the shock absorber plane bearing lacks oil, applying some grease can solve the problem. 3. Loose stabilizer bar bushing: If the noise does not come from the shock absorber's plane bearing, check whether the stabilizer bar bushing is loose or damaged. A loose or damaged stabilizer bar bushing will not only cause noise when turning the steering wheel but also when driving on uneven roads. A loose stabilizer bar bushing can be fixed by adding shims. 4. Dirty power steering fluid: If the power steering fluid is too dirty, it will increase the pressure in the power steering system, and the power steering fluid should be replaced promptly.
