Wheel bearings are the most important part of a vehicle powertrain. Whenever they start to malfunction, the hub bearings usually whine, and you can feel it through the steering wheel or the car's chassis. Encountered bearing noise is a very bad thing, which makes us locate the problem as soon as possible to find the place. Fortunately, the solution to the source of the problem is listening and listening to every corner of your car.
The following is a specific way:
1, find a large, open parking, 45 miles / hour speed in the parking lot, turn.
2, stepping on your brakes as if you had a panic and stop that. The front of the car plunges and the weight shifts to the front, putting more pressure on the bearings. Listen to the sound of your axle at this moment, and if it's turned up, then you have a bad front bearing. If it gets quieter or disappear, then you have a bad rear bearing.
3, driving at a speed of 45 miles / hour to make a circular drive, first turn clockwise, you will bear the weight of the car seat. If the bearing noise becomes loud, the bad bearing is in the driver's seat. Then repeat counterclockwise again, if bearing noise becomes loud, bad bearings on the passenger's side.
4, if you find the bearing noise or vibration increases, then the bad bearings are on the side of the front passenger. If the brakes and reduce the bearing noise increases, then the bad bearings on the side of the rear wheel driver.
