Why is there a creaking sound when turning the steering wheel?

[McJeremiah]

Vehicle steering wheel abnormal noise should be judged based on the specific location of the sound source. The specific reasons for abnormal noise when turning the steering wheel are as follows: 1. Abnormal sound from turn signal return spring damage: If this sound only occurs after activating the turn signal switch, it's the sound from the turn signal auto-return mechanism's return spring, which is normal. 2. Sound from steering column dust cover: Whether stationary or moving, if you hear sounds coming from below the steering wheel when turning it, check the steering column dust cover. Lack of lubrication in the dust cover will cause dry friction sounds. Applying some grease inside the dust cover will eliminate this sound.
