In hot weather, the steering wheel turns left and there is abnormal noise.

Hello, the whine of the car steering wheel is caused by the following reasons:

First, if it's the sound inside the car.

1, the sound of the rebound clip behind the turn signal

If you turn the steering wheel after turning the steering switch, it will make this sound, which is the sound made by the rebound clip of the automatic return mechanism of the turn signal. This sound is normal. It will make a knot sound when you hit the steering wheel, and it will make a knot sound when the steering wheel rotates once. This sound only occurs when the steering column has three automatic return positions. Just turn off the turn signal and the sound will disappear.

2. Noise from steering column dust cover

No matter where you are and when you drive, you will hear the sound coming from under the steering wheel. Check the steering column dust cover. Once the steering column dust cover lacks lubrication, it will produce dry rubbing sound. All you have to do is put some butter on the dust cover, and the sound will disappear.

3. The sound produced by the interference of the air bag hairspring

When driving in direction, the sound comes from the inside of the steering wheel. This problem is mostly caused by the interference of the airbag hairspring in the steering wheel. Take off the airbag hairspring from the steering wheel and spread some butter to see if it will ring again. If yes, replace the airbag hairspring, because the airbag hairspring has been damaged.

Second, if it's the sound outside the car.

1. Sound from plane bearing of shock absorber

The sound heard by turning the steering wheel comes from many cars, which may be caused by the lack of oil in the plane bearing of the shock absorber. You only need to open the hood and listen to whether the sound comes from the top seat of the shock absorber, so you can know whether it is the sound from the plane bearing of the shock absorber. The plane bearing of the shock absorber is ringing, so you can put some butter on it. If it is still ringing after painting, you can only replace it.

2. The sound made by the loose rubber of the balance bar

The sound is not from the plane bearing of the shock absorber, so it is necessary to check whether the rubber of the balance bar is loose or damaged. If the rubber of the balance bar is loose or damaged, there will be a sound not only in the direction of hitting, but also in the uneven road. The rubber of the balance bar can be loosened by adding gaskets, and it can only be replaced if it is damaged.
