What Causes the Friction Sound When Turning the Mercedes Steering Wheel?
1 Answers
Small car steering wheel turning with abnormal noise may be due to steering wheel issues or stabilizer bar problems. Steering wheel issues: If the abnormal noise comes from inside the steering wheel, the problem is most likely caused by the clock spring inside the steering wheel. Remove the steering wheel clock spring and apply some grease to see if the noise persists. If it still makes noise, replace the clock spring. Be gentle when removing the steering wheel, or disconnect the airbag fuse to prevent the airbag from deploying. Stabilizer bar problems: If the noise is not coming from the shock absorber, check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings will not only cause noise when turning the steering wheel but also when driving on uneven roads. Loose stabilizer bar bushings can be fixed by adding shims, but if they are damaged, they must be replaced.
