What Causes the Squeaking Sound When Turning the Steering Wheel?

[JulietteDella]

The reasons for the squeaking sound when turning the steering wheel: 1. Friction between plastic components: Since the steering wheel is composed of plastic parts, if the temperature drops, the plastic may harden, naturally leading to friction noises; 2. Noise from inside the steering wheel: If the noise comes from inside the steering wheel, it is likely caused by the clock spring (airbag coil). Try removing the steering wheel's clock spring, applying some grease, and checking if the noise persists. If it does, replace the clock spring; 3. Aging of the tie rod end ball joint: If the tie rod end ball joint ages, it can cause the steering wheel to shake and produce noise. In this case, the tie rod end ball joint should be replaced, followed by a wheel alignment; 4. 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 noises 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.
