The appearance of the problem: When one of the four wheel bearings of the vehicle is damaged; when the car is moving, you will hear a series of buzzing sounds in the car; this kind of movement can't tell where it was announced; feel the whole The car is full of such buzzing sounds; and the faster the car speed, the greater the movement; usually the car speed can be heard from the beginning of 60km/h; the speed is 70, 80km/h; 100km/h h when the car talks to improve the trick; at this moment there is a fine oscillating feeling on the soles of the feet. These are only the surface appearance of the problem; if it is the first time you really can't understand it is awkward; let's talk about the way to identify this problem.
Judging method: When you hear this kind of movement in the driving process, you don't need to be nervous; insist on calming and driving continuously; use these methods to roughly judge the sound source;
1. Open the window and listen to whether the movement can come from outside the car.
2. After the speed is improved, the gear position will be in the neutral position to let the vehicle taxi; investigate whether the noise can come from the engine; if the squeaking does not change when the neutral is sliding, most of the wheel bearings have problems.
3, temporary parking; get off the car to check whether the temperature of the axle can be normal; the way is: do not touch the four wheels by hand; roughly feel their temperature can be common; if it feels different, sustainable slow speed to service centre,
4. Raise the car with a lift; use the jack to raise the wheel one by one without the lift; the manpower will change the four wheels quickly; when encountering a problematic axle; it will announce the movement; it is completely different from the other axle; It is very simple to use this method to distinguish which axle has a problem. If there are accessories, you can directly replace the parts to eliminate the problem; if there is no accessories? Then you have to take the disease to drive; the following said the following matters when traveling.
Driving precautions: This is actually nothing to say; driving in accordance with the normal driving method, follow the traffic regulations is OK. But there is a point to be uniquely careful; is to try to adhere to low-speed driving; the intention is to avoid excessive speed will form damage The temperature of the bearing rises sharply; the end causes the axle to lock and the vehicle to slip.
