The SKF bearing of the car's wheel is noisy. This seemingly impossible fault does exist in reality. Let's discuss it together.
Trouble phenomenon: When one of the four wheels of the vehicle's SKF bearing is damaged, you will hear a continuous squeaking noise in the car while driving. This sound can't tell where it came from. I feel that the entire compartment is full of such buzzing sounds, and the faster the speed, the louder the sound, the general speed can be heard from 60km/h, and the sound is obvious at 70km/80km/h. At 100km/h, the conversation in the car should be improved, and the soles of the feet have a fine vibration feeling. These are just superficial phenomena of failure. If it is the first time you encounter it, you really can't understand what is going on. Let's talk about the way to judge this fault.
Judgment method: When you hear this kind of squeaking sound during driving, don't panic, keep calm and continue driving, use these methods to judge the sound source roughly.
1. Open the window and hear if the sound comes from outside the car;
2. After increasing the speed (when the noise is loud), the gear position is in the neutral position to let the vehicle slide, and observe whether the noise comes from the engine. If the noise does not change when the neutral gear slides, most of the problems are caused by the wheel SKF bearing;
3. Temporary parking, get off and check if the temperature of the axle is normal. The method is: touch the four wheels by hand and feel the temperature is consistent. (When the brake shoes and the gap are normal, the temperature of the front and rear wheels is The gap, the front wheel should be high), if you feel the difference is not big, you can continue to drive slowly to the repair station;
4. Raise the car with the lift (previously release the handbrake and hang the neutral). When there is no lift, the jack can be used to raise the wheel one by one. The manpower will rotate the four wheels quickly. When the problematic axle is encountered, it will make a sound. It is completely different from other axles. It is easy to tell which one is used by this method.
