Product Description

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) 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, 90142161 43202-8H3 41204-6 41204-6 41204-35080 42409-34571 7701205471 43202-JG2 43401-65710 422AB 43502-0D080 3880A056 52710-2C 446 F0DC-2B644AB 422BA 1R3Z-1104BA 51750-1PBA 1F22-2B664-AB 28052-AA571 44600-S5D-A00 33412282675 93557106 42201-S10-A01 42200-SR3-A06 44600-SDA-A10 6E5Z-1104-AB MR223285 96268475 42200-SS0-981 DACF1050B 43200-9F510

What are the key differences between live axles and dead axles in vehicle design?

In vehicle design, live axles and dead axles are two different types of axle configurations with distinct characteristics and functions. Here’s a detailed explanation of the key differences between live axles and dead axles:

Live Axles:

A live axle, also known as a solid axle or beam axle, is a type of axle where the wheels on both ends of the axle are connected and rotate together as a single unit. Here are the key features and characteristics of live axles:

  1. Connected Wheel Movement: In a live axle configuration, the wheels on both ends of the axle are linked together, meaning that any movement or forces applied to one wheel will directly affect the other wheel. This connection provides equal power distribution and torque to both wheels, making it suitable for off-road and heavy-duty applications where maximum traction is required.
  2. Simple Design: Live axles have a relatively simple design, consisting of a solid beam that connects the wheels. This simplicity makes them durable and capable of withstanding heavy loads and rough terrains.
  3. Weight and Cost: Live axles tend to be heavier and bulkier compared to other axle configurations, which can impact the overall weight and fuel efficiency of the vehicle. Additionally, the manufacturing and maintenance costs of live axles can be lower due to their simpler design.
  4. Suspension: In most cases, live axles are used in conjunction with leaf spring or coil spring suspensions. The axle is typically mounted to the vehicle’s chassis using leaf springs or control arms, allowing the axle to move vertically to absorb bumps and provide a smoother ride.
  5. Off-road Capability: Live axles are commonly used in off-road vehicles, trucks, and heavy-duty applications due to their robustness, durability, and ability to deliver power to both wheels simultaneously, enhancing traction and off-road performance.

Dead Axles:

A dead axle, also known as a dummy axle or non-driven axle, is a type of axle that does not transmit power to the wheels. It is primarily used to provide support and stability to the vehicle. Here are the key features and characteristics of dead axles:

  1. Independent Wheel Movement: In a dead axle configuration, each wheel operates independently, meaning that the movement or forces applied to one wheel will not affect the other wheel. Each wheel is responsible for its own power delivery and traction.
  2. Weight Distribution: Dead axles are often used to distribute the weight of the vehicle more evenly, especially in cases where heavy loads need to be carried. By adding an extra axle without driving capability, the weight can be distributed over a larger area, reducing the load on other axles and improving stability.
  3. Steering: Dead axles are commonly used as front axles in vehicles with rear-wheel drive configurations. They provide support for the front wheels and allow for steering control. The steering is typically achieved through a separate mechanism, such as a steering linkage or a steering gear.
  4. Reduced Complexity: Dead axles are simpler in design compared to live axles since they do not have the additional components required for power transmission. This simplicity can lead to lower manufacturing and maintenance costs.
  5. Efficiency and Maneuverability: Dead axles are often used in vehicles where power delivery to all wheels is not necessary, such as trailers, certain types of buses, and some light-duty vehicles. By eliminating the power transmission components, these vehicles can achieve better fuel efficiency and improved maneuverability.

It’s important to note that the choice between live axles and dead axles depends on the specific application, vehicle type, and desired performance characteristics. Vehicle manufacturers consider factors such as load capacity, traction requirements, off-road capability, cost, and fuel efficiency when determining the appropriate axle configuration for a particular vehicle model.


What is the difference between front and rear axles in a typical vehicle?

In a typical vehicle, there are distinct differences between the front and rear axles due to their respective roles and functions. Here are the key differences:

  1. Position:
  2. The main difference between the front and rear axles is their position in the vehicle. The front axle is located in the front of the vehicle, while the rear axle is positioned at the rear. This positioning is determined by the vehicle’s drivetrain configuration.

  3. Steering:
  4. The front axle is responsible for steering the vehicle. It is connected to the steering system, allowing the driver to control the direction of the vehicle. The front axle typically includes components such as steering knuckles, tie rods, and steering linkages.

  5. Driving:
  6. The rear axle is primarily responsible for driving the vehicle’s wheels. It receives power from the engine through the transmission or differential and transfers that power to the rear wheels. The rear axle may include components such as axle shafts, differential gears, and wheel hubs.

  7. Suspension:
  8. Both the front and rear axles play a role in the vehicle’s suspension system, but their configurations and functions differ. The front axle typically incorporates suspension components such as control arms, struts, or independent suspension systems to provide better handling, stability, and ride comfort. The rear axle may have a solid axle setup or independent suspension depending on the vehicle’s design.

  9. Load Distribution:
  10. The load distribution on the front and rear axles varies. In a typical vehicle, the front axle carries the weight of the engine, transmission, and a portion of the vehicle’s weight due to the front-end weight bias. The rear axle bears the weight of the vehicle’s occupants, cargo, and a portion of the vehicle’s weight. This distribution helps maintain proper balance and stability during acceleration, braking, and cornering.

  11. Driving Characteristics:
  12. The differences between the front and rear axles can influence the vehicle’s driving characteristics. The front axle’s role in steering affects the vehicle’s maneuverability and responsiveness. The rear axle’s responsibility for driving the wheels affects traction, acceleration, and stability, particularly in rear-wheel drive or four-wheel drive vehicles.

It’s important to note that the specific configurations and characteristics of front and rear axles can vary depending on the vehicle’s make, model, and drivetrain system. Different types of vehicles, such as front-wheel drive, rear-wheel drive, or all-wheel drive, may have variations in axle design and functionality.

Understanding the differences between the front and rear axles is essential for proper maintenance, repairs, and modifications of the vehicle’s drivetrain and suspension systems. If you have specific questions about your vehicle’s axles, it’s recommended to consult your vehicle’s owner’s manual or seek advice from qualified mechanics or automotive professionals.


How do solid axles differ from independent axles in terms of performance?

When comparing solid axles and independent axles in terms of performance, there are several key differences to consider. Both types of axles have their advantages and disadvantages, and their suitability depends on the specific application and desired performance characteristics. Here’s a comparison of solid axles and independent axles:

Aspect Solid Axles Independent Axles
Load-Bearing Capability Solid axles have high load-bearing capability due to their robust and sturdy construction. They can handle heavy loads and provide excellent stability, making them suitable for off-road vehicles, heavy-duty trucks, and towing applications. Independent axles typically have lower load-bearing capability compared to solid axles. They are designed for lighter loads and offer improved ride comfort and handling characteristics. They are commonly used in passenger cars, sports cars, and vehicles with a focus on maneuverability and road performance.
Wheel Articulation Solid axles have limited wheel articulation due to their connected and rigid design. This can result in reduced traction and compromised wheel contact with the ground on uneven terrain. However, solid axles provide excellent traction in situations where the weight distribution on all wheels needs to be maintained, such as in off-road or rock-crawling applications. Independent axles offer greater wheel articulation as each wheel can move independently of the others. This allows the wheels to better conform to uneven terrain, maximizing traction and maintaining contact with the ground. Independent axles provide improved off-road capability, enhanced handling, and better ride comfort.
Ride Comfort Due to their rigid design, solid axles generally provide a stiffer and less compliant ride compared to independent axles. They transmit more road shocks and vibrations to the vehicle’s occupants, resulting in a rougher ride quality. Independent axles are known for providing better ride comfort. Each wheel can react independently to road imperfections, absorbing shocks and vibrations more effectively. This leads to a smoother and more comfortable ride, particularly on paved roads and surfaces with minor irregularities.
Handling and Stability Solid axles offer excellent stability due to their connected nature. They provide better resistance to lateral forces, making them suitable for high-speed stability and towing applications. However, the rigid axle design can limit overall handling and maneuverability, particularly in tight corners or during quick direction changes. Independent axles generally offer improved handling and maneuverability. Each wheel can react independently to steering inputs, allowing for better cornering performance and agility. Independent axles are commonly found in vehicles where precise handling and responsive steering are desired, such as sports cars and performance-oriented vehicles.
Maintenance and Repair Solid axles are relatively simpler in design and have fewer moving parts, making them easier to maintain and repair. They are often more resistant to damage and require less frequent servicing. However, if a component within the axle assembly fails, the entire axle may need to be replaced. Independent axles are typically more complex in design and have multiple moving parts, such as control arms, CV joints, or bearings. This complexity can result in higher maintenance and repair costs. However, if a failure occurs, only the affected component needs to be replaced, reducing repair expenses compared to replacing the entire axle.

It’s important to note that advancements in suspension and axle technologies have resulted in various hybrid systems that combine features of solid and independent axles. These systems aim to provide a balance between load-bearing capability, wheel articulation, ride comfort, and handling performance based on specific application requirements.

In summary, solid axles excel in load-bearing capability, stability, and durability, making them suitable for heavy-duty applications and off-road conditions. Independent axles offer improved ride comfort, better wheel articulation, enhanced handling, and maneuverability, making them suitable for passenger cars and vehicles focused on road performance. The choice between solid axles and independent axles depends on the specific needs and priorities of the vehicle or machinery.
