What Causes the Abnormal Noise When the Car Turns?

[DiAriel]

Abnormal noise when the car turns may be caused by the following situations: 1. The sound from the turn signal returning to position. If the turn signal is activated while turning, this sound is produced by the return mechanism's spring clip of the turn signal. 2. Friction between plastic parts. The steering wheel is usually made of plastic components. If the temperature drops, the plastic may harden, potentially causing friction noise. 3. Abnormal noise from the steering wheel. If the noise comes from inside the steering wheel, the issue is likely due to the clock spring of the airbag. 4. Aging of the tie rod end ball joint. An aged tie rod end ball joint can cause the steering wheel to shake and produce noise. In this case, the tie rod end ball joint usually needs to be replaced, followed by a four-wheel alignment. 5. Steering gear failure. If the noise during steering is very loud, it may be caused by excessive gear clearance in the steering gear, requiring replacement of the steering gear. 6. Abnormal noise from the shock absorber top bearing. Open the hood and listen to see if the noise is coming from the shock absorber top mount. If it is, the noise is likely from the shock absorber top bearing. Applying grease to the top bearing may help; if the noise persists, replacement is necessary. 7. Noise from the stabilizer bar. If the noise is not from the shock absorber, check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings can cause noise not only when turning but also when driving on uneven roads. Loose bushings can be fixed by adding shims, while damaged ones need to be replaced.
