Car wheels SKF bearings noise, this seemingly impossible fault in reality it does exist, here we work together to explore.
Symptom: When the vehicle four wheels SKF bearings in a damaged, the car in the car you will hear in the car a continuous hum - hum - hum, this voice can not tell where it is issued The feeling of the whole car are filled with this buzz, and the faster the faster the voice, the general speed from 60km / h or so when you can hear a slight buzz, speed 70,80km / h feel obvious , 100km / h car conversation to improve the voice, this time the foot has a fine vibration feeling. These are just the surface of the fault phenomenon, if it is the first time I really do not understand it is Editor's Note, the following talk about the way to judge this failure.
Judgment method: When you are in the process of moving this buzzing sound when you do not have to panic, keep calm and continue to drive, with so few ways to roughly determine the sound source,
1, open the window to listen to the sound is from outside the car;
2, to improve the speed (buzz when the larger) will be stalls in the neutral gear to allow vehicles to glide, observe whether the noise from the engine, if the neutral gear when the buzz does not change that most of the wheel SKF bearings have problems;
3, temporary parking, get off to check the axle temperature is normal, the method is: hand, respectively, touch the four wheels, roughly feel their temperature is consistent (brake shoes, the gap between the normal, the front and rear wheel temperature is Gap, the front wheel to a high point), if the feeling is not very slow to continue to drive to the maintenance station;
4, with the lift to raise the car (before the release of handbrake, hanging air), no lift can jack up one by one wheels, manpower, respectively, quickly turn the four wheels, when the problem encountered axle, it will sound , And other axles are completely different, with this method is easy to distinguish which axle has a problem. There is a direct accessory parts can be troubleshooting, if there is no accessories supposed to? It would have to sick of the road, the following said under the driving time to note.
