  Wheel hubBearing iscarAn important part of the wheel hub. The main function of the hub bearing is to provide precise guidance for the rotation of the hub. It not only bears axial load, but also bears radial load. Once the car breaks down, there will be all kinds of failures. Next, we will understand the symptoms of wheel bearing failure and how to determine the inspection method of wheel bearing failure.

The front wheel bearing is on the front wheel of the car. If the front wheel bearing of the wheel is damaged, it is not very serious. When the wheel bearing is opened, the noise will be loud.When the wheel bearing is damaged, it will send out andtireDifferent buzzing noise. You can drive for half an hour and touch the hub of the bearing with the back of your hand after getting out of the car. If the bearing is damaged, the heat generated will be very high. It is estimated that the hands will be very hot. It is different from room temperature. If it is decisive, replace it. If severe thermal damage occurs, it will generate faster heat, which will damage your shaft and end caps.This is not sloppy, variable speed, goAuto partsCity buyAccessoriesCall the maintenance department. Because 4S shops will be expensive and unnecessary.

If the driver hears the noise of the hub bearing, first of all, it is important to find the location of the noise. There are many moving parts that may generate noise, or some rotating parts may be in contact with non-rotating parts. If it is confirmed that there is noise in the bearing, the wheel bearing is damaged and needs to be replaced immediately.

  Symptoms of wheel bearing damage

  First of all, when the car is driving, the wheels will shake, and the whole car will shake violently.

Secondly, if the bearing is damaged, there will be abnormal noise.

  Thirdly, poor rolling results in a drop in power. The biggest impact is the increase in body shaking and abnormal noise. It is recommended to replace.

  How to judge wheel bearing failure

  1. Open the car window and listen to whether the sound is coming from outside the car.

Second, increase the vehicle speed (when the hum is loud), set the gear position in neutral, and let the vehicle coast. Observe whether the noise comes from the engine. If the hum does not change when coasting in neutral, it is mainly a wheel bearing problem.

three. Stop temporarily and check whether the axle temperature is normal. The method is to touch the four wheel hubs with your hands to roughly feel whether their temperatures are the same (when the brake shoes and clearance are normal, the temperature of the front wheel and the rear wheel are different, and the front wheel should be high). If the difference is not significant, you can continue to drive slowly to the repair station.

Four. Use the elevator to lift the car (before releasing the handbrake and putting in neutral).When notLiftWhen you can usejackLift the wheels one by one. Human power can quickly turn four wheels. When there is a problem with the axle, it will make a sound. It is completely different from other axles. In this way, it is easy to distinguish which axis has the problem.

Testing method

(1) Grasp the wheel, push up and down, and check whether the wheel bearing is loose.

(2) When an abnormality is found, one person sits on the driver’s seat and steps onbrake, The other person hugged the wheel again, pushed and pulled the wheel up and down and shook it. If there is looseness, it may be caused by excessive looseness of the bearing. The bearings should be checked.

When adjusting the bearing clearance according to the maintenance manual, especially for tapered roller bearings, a certain clearance should be reserved and do not tighten, otherwise it will wear, overheat or burn.
