Long-term wading is the incentive-How to extend the service life of auto wheel hub bearings and axle spindle sub-assy?
With the increase of vehicle HangZhouage, many drivers have encountered the problem of abnormal wheel noise. And this kind of abnormal noise is often related to the speed of the vehicle, the faster the speed, the greater the abnormal noise. Many people think it is tire noise and ignore it. As everyone knows, this is likely to be the abnormal noise caused by the wear of the wheel hub bearing. Do you know what causes the abnormal sound of the wheel hub bearing? How can we prolong its life? Today, HangZhou Xihu (West Lake) Dis.na will talk to you about what should be paid attention to when using wheel bearings!
1.Fault phenomenon of wheel hub bearing
1.1Abnormal noise: There is a “buzzing” abnormal sound on a certain wheel when the vehicle is driving. As the speed of the vehicle increases, the abnormal sound goes home.
1.2 Clearance: There is a radial clearance in the left and right shaking wheels. If the clearance is serious, the steering wheel will vibrate or deviate when the vehicle is driving.
2.Second, what is likely to cause damage to the wheel hub bearing?
2.1 Water wading: wading is the most important factor threatening the service life of wheel bearings. If you drive in deep water for a long time, especially where the water depth is more than half of the wheel, it is easy to cause the bearing to seep and rust, resulting in internal wear.
2.2 Loose bolts: The wheel hub bearings of some models are fastened by CV JOINT nuts. If the nuts are loose for a long time, the bearings will wear out.
2.3 Damage to the wheel hub bearing sealing ring: In order to prevent dust and sewage from entering the interior of the wheel bearing and prevent the internal grease from being thrown out, the hub bearing will be designed with a sealing ring. Long-term wear and aging of this sealing ring will lead to poor sealing and internal water ingress.
3. Where is the wheel hub bearing installed?
Hub bearings are installed inside the steering knuckle of the wheel. Divided into integrated bearings with the hub and independent bearings. The 4 wheels are respectively equipped with 4 wheel hub bearings. After a certain bearing fails, the abnormal sound produced by the wheel on 1 side will be obviously heard. If the wear is serious, the abnormal sound will be more obvious if the wheel is suspended in the air and rotated.
4. Disassembly and assembly of wheel hub bearings
4.1 Disassemble the wheel: the design of the wheel hub bearing of each model is different, so I will not introduce it in detail. Briefly explain how to disassemble the hub bearing. Take off the wheel after suspending the wheel first.
4.2 Disassemble the CV JOINT nut: the bearings are fastened through the CV JOINT nut, so we need to check the tightness of the CV JOINT nut regularly. It’s okay to have a lock like this. If not, the nuts need to be tightened periodically. To remove the bearing, the CV JOINT nut must be removed.
4.3 Disassemble the brake system: the next step is to disassemble the brake calipers and brake discs. For most of the Wheel bearings integrated with the hub shaft, it can basically be removed after the brake disc is removed.
4.4 Remove the wheel bearing: if it is an integrated bearing, that is, the bearing and the hub shaft are designed in 1 piece. This type of bearing cannot be repaired. After damage, it can only be replaced once, and the maintenance cost is slightly higher.
5. How to prolong the service life of auto wheel hub bearings and axle spindle?
5.1 Avoid time wading.
5.2 Regularly check whether the CV JOINT nut is loose.
5.3 During each maintenance, shake the wheel to check whether there is a radial gap. If there is, check whether the gap can be eliminated by tightening the CV JOINT nut.
5.4 For maintainable bearings, the hub bearings should be cleaned and oiled every 40,

What is a CV axle, and what role does it play in a vehicle’s drivetrain?
A CV axle, also known as a constant velocity axle or drive axle, is an essential component in a vehicle’s drivetrain. It plays a crucial role in transferring power from the transmission to the wheels, allowing the vehicle to move forward or backward. Here’s an explanation of what a CV axle is and its role in a vehicle’s drivetrain:
Definition:
A CV axle is a shaft that connects the transmission or differential to the wheels of a vehicle. It is designed to transmit torque from the engine and transmission to the drive wheels, allowing the wheels to rotate at variable speeds while maintaining a constant velocity. The CV axle consists of an inner and outer joint connected by a flexible CV boot, which contains grease and protects the joints from dirt and debris.
Role in the Drivetrain:
The CV axle plays several important roles in a vehicle’s drivetrain:
1. Power Transmission:
One of the primary roles of the CV axle is to transmit power from the engine and transmission to the drive wheels. As the engine generates torque, it is transferred through the transmission to the CV axle, which then delivers the power to the wheels. This allows the vehicle to move forward or backward, depending on the gear selection.
2. Flexibility and Constant Velocity:
The CV axle is designed with flexible joints, known as CV joints, which allow for smooth power transmission even when the wheels are turning at different speeds, such as during turns or when encountering uneven terrain. The CV joints maintain a constant velocity, minimizing vibrations and ensuring a smooth and comfortable ride for the occupants.
3. Suspension and Steering:
The CV axle is an integral part of the suspension and steering system. It connects the wheel hub assembly to the transmission or differential, allowing the wheels to move vertically with the suspension while maintaining power delivery. Additionally, the CV axle contributes to the vehicle’s steering by transmitting torque to the wheels, enabling the driver to control the direction of the vehicle.
4. Absorption of Road Impacts:
The CV axle, along with the suspension system, helps absorb road impacts and shocks, providing a smoother and more controlled ride. The flexibility of the CV joints allows them to compensate for changes in wheel position and accommodate variations in road surface conditions, reducing the impact felt by the vehicle’s occupants.
5. Support and Load Bearing:
The CV axle supports the weight of the vehicle and bears the load transferred from the wheels. It must be designed to handle the forces and stresses encountered during acceleration, deceleration, and cornering. The CV axle’s strength and durability are crucial for maintaining the integrity and performance of the drivetrain.
Overall, the CV axle plays a vital role in a vehicle’s drivetrain by transmitting power, accommodating variable speeds, contributing to suspension and steering, absorbing road impacts, and supporting the vehicle’s weight.
