A sign of a broken rear wheel bearing.
The bearing is the key to the installation of the quality of the car body, and at the same time, the main component of the tire to give rotation work ability, its office environment can be described as very extreme. It is not only necessary to deal with the working pressure and vibration in the whole process of vehicle driving, but also to bear the erosion of precipitation and stone. In such strict conditions, even the best tire bearings can not ensure that they can be durable.
About the front tire bearing damage we have already talked about its detailed omen, then let's understand the car rear tire bearing damage and what are the main manifestations of it.
The main manifestation of broken rear tire bearing
1. Wheel shake: When the car is driving, if the wheel appears obvious shake, the vehicle shake will be more obvious. This is usually caused by wheel bearing damage.
2. Abnormal noise: If you hear abnormal noise during driving, such as clicking, buzzing, etc., it may be a sign of wheel bearing damage.
3. Poor rolling: When the car is driving, if you feel the wheel rolling is not smooth, the power is decreased, which may also be one of the reasons for the wheel bearing damage.
If the above symptoms are found, it is recommended to go to a professional auto repair shop for inspection and replacement in time. If not repaired in time, tire bearing damage will bring a lot of harm, such as light vehicle deviation, tire noise, vehicle power decline, affect comfort, and even cause serious suspension damage, wheel mechanism damage, wheel hub loss and other safety hazards. Therefore, the inspection and maintenance of wheel bearings is very important.
Replace the rear wheel bearing tutorial
1. First, ensure that the vehicle has stopped on a flat ground, and use a jack to lift the vehicle and remove the tires.
2. Find the setting screw for the bearing, usually located on the inside edge of the wheel. Unscrew these screws to remove the old bearing.
3. Use a wrench or special tool to remove the bearing cover. This housing is usually made of plastic and can be easily unscrewed with a wrench.
4. Carefully remove the old bearing from the bearing seat. This process may require some effort, as the bearing is usually stuck to the bearing seat. You can use a screwdriver or other suitable tool to help separate them.
5. If the bearing is damaged or seriously worn, it needs to be replaced with a new bearing. When buying new bearings, make sure they match the model of your car.
6. When installing new bearings, reverse operation can be performed according to the order of disassembly.
7. Finally, reinstall the tires and put the vehicle down. Before driving, check that the tire pressure is normal.
The life of bearings is generally affected by a variety of factors, including manufacturing quality, service conditions, load size, speed and so on. According to the information provided, the life of imported bearings is generally between 2 and 5 years, while the life of domestic bearings is between 2 and 4 years.
For specific applications, such as automotive wheel bearings, they are often designed to handle higher stresses and harsher environmental conditions, so their life can exceed 100,000 km.
The life of a bearing can also be defined by the number of revolutions or hours it experiences before pitting occurs, which is called the rated life of the bearing. Different bearings due to their manufacturing accuracy and material uniformity differences, even under the same working conditions, its actual life will be different. For example, some bearings may only be able to use 0.1-0.2 units of time, while some can reach 4 units of life, the ratio between which can reach 20-40 times.
In summary, the life of a bearing depends on a number of factors, including its type, conditions of use, and manufacturing quality. Under normal circumstances, the life of imported bearings ranges from 2 years to 5 years, and domestic bearings from 2 years to 4 years. For automotive applications, the life of the bearing can exceed 100,000 km. It is important to select the right bearings according to the specific application conditions, and carry out regular inspection and replacement in accordance with the manufacturer's recommendations to ensure the reliability and safety of the equipment.
