How to find hub bearing noise?


The wheel bearing is the most important and the most important part of the vehicle power transmission system. When they start to fail, the hub bearings usually purr, and you can feel it through the steering wheel or the chassis. Bearing noise is a very bad thing, which makes it necessary to locate the problem as soon as possible. Fortunately, the solution to the source of trouble is to listen and listen to every corner of your car.
The following are specific measures:
1. Find a big, open parking lot, 45 miles per hour, driving and turning in the parking lot.
2, step on your brakes as if you were caught in a panic and stopped. The front of the car will crash, the weight will shift to the front, and the bearings will exert more pressure. Listen to the sound of your axle, and if it's up, you have a bad front bearing. If it gets quieter or disappears, then you have a bad rear bearing.
3, driving at a speed of 45 miles per hour for a circle, turn clockwise first, and you will bear the weight of the car at the side of the driver's seat. If the bearing noise becomes loud, the bad bearings are in the driver's seat. And then repeat it counterclockwise, if the bearing noise becomes loud, the bad bearing is on the side of the passenger.
4, if you find that the bearing noise or vibration increases, then the bad bearing is the front passenger side. If the brake and reduce the noise of the bearing increase, then the bad bearing on the rear wheel driver side.
