You can check and deal with it from the following aspects; 1. Abnormal noise while driving the steering wheel. First of all, it is necessary to know where the noise comes from. Whether it's the sound inside the car or the sound outside the car. Different sound sources will cause different problems. The sound from the car is 1, and the sound from the rebound clip when the turn signal is turned on. You can only hear this sound when you turn on the steering wheel after turning on the turn signal. That's the sound of the return clip of the automatic return mechanism of the turn signal. This kind of sound is normal. Turning the steering wheel in the right direction will make a knot sound, and turning the steering wheel once will make a triple knot sound. This sound will only appear when the steering column automatically returns to a stop three times during one rotation. 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 the sound of dry friction. All you have to do is put some butter on the dust cover, and the sound will disappear. 3. When the air bag hairspring interferes with the direction, the sound comes from the steering wheel. This problem is mostly caused by the interference of the airbag hairspring in the steering wheel. Remove the airbag hairspring of the steering wheel and apply some butter to see if it still rings. If it still rings, replace the airbag hairspring, because the airbag hairspring has been damaged.
