A Great Wall differential is an essential component of the four-wheel-drive system. Its main objective is to allow the drive wheels to rotate at different speeds. This is especially important when taking turns since it reduces tire wear and improves vehicle stability. There are several types of Great Wall 4x4 differentials, including:
Open differential
The most commonly used type of differential in four-wheel-drive vehicles is the open differential. It is also known as the conventional differential. The open differential divides torque equally between the drive wheels. It also allows them to rotate at different speeds. When turning, the outer wheel travels a longer distance than the inner wheel. If both wheels have the same amount of traction, the outer wheel will spin faster than the inner wheel, causing the differential to act. As a result, both wheels will spin at the same speed, and the vehicle won't move. As a workaround, a locking differential can be used.
Locking differential
A locking differential, also known as the "lock diff," is a device used in four-wheel-drive vehicles. The locking differential acts like an open differential in normal driving conditions. However, it can be locked manually or automatically when needed, such as when driving on very slippery surfaces or when stuck in mud. Locking differentials are especially useful in off-road situations where maximum traction is required.
Limited slip differential
A limited-slip differential (LSD) is a device used in four-wheel-drive vehicles. The limited-slip differential acts like an open differential in normal driving conditions. It allows the drive wheels to rotate at different speeds, particularly when turning. However, it also limits the difference in speed between the two drive wheels. This means that if one wheel starts to slip or spin faster than the other, the LSD will transfer some torque to the wheel with more traction. As a result, both wheels will work together to provide better traction and stability, especially on slippery or uneven surfaces.
The differential specification varies depending on the type of axle and the model of the Great Wall car.
1. Differential Fluid Change:
Great wall differential fluid is essential for lubrication. Check the fluid level regularly, at least once a month. If the fluid level drops, refill it to the recommended level. Use the fluid specified by the manufacturer when changing the fluid. Changing the fluid helps remove contaminants and maintain smooth operation. Follow the service intervals in the owner's manual for fluid changes. Typically, fluid changes are required every 30,000 to 60,000 km, depending on driving conditions.
2. Inspect Seals and Gaskets:
Inspect all seals and gaskets around the differential housing. Look for signs of leaks or cracks that could cause fluid loss. Replace any damaged seals promptly to prevent leaks. Leaking fluid can lead to differential damage over time. Check the mounting bolts that hold the differential in place. Ensure all bolts are tightened to the specified torque. Loose bolts can cause the differential to shift and affect driveline alignment. Unbalanced axles may result in uneven tire wear.
3. Monitor Differential Noise:
Great Wall car owners should pay attention to any unusual noises coming from the differential area when driving. Grinding or whining sounds could indicate worn internal components like bearings or gears. Have a qualified technician inspect the differential if noises are detected. Addressing issues early can prevent more costly repairs later.
4. Check Wheel Bearing Play:
Great Wall SUVs and cars have wheel bearings that support axle rotation. Excessive play in the wheel bearings can put extra stress on the differential. Use a dial indicator to measure bearing endplay. If play exceeds the manufacturer's specified limits, the wheel bearings should be replaced.
5. Inspect Driveshaft U-joints:
The driveshaft transfers power from the transmission to the axles. Inspect the universal joints (U-joints) at regular intervals. Look for signs of wear like play or binding. Worn U-joints can cause vibration issues that affect differential performance. Replace any worn U-joints to maintain smooth power delivery.
6. Monitor Tire Wear:
Great Wall 4x4 differential relies on properly matched tires for balanced traction distribution. Unevenly worn tires can cause differential stress over time. Use a tread depth gauge to check all tires for even wear. Replace tires when they reach the minimum tread depth or show significant differences in wear patterns.
Choosing the right Great Wall differential involves considering various factors to ensure optimal performance and compatibility with specific needs. Here are some factors to consider:
Vehicle Compatibility
It's important to consider the size and type of the differential before deciding. This is because the differential is constructed to fit a particular model car. Don't forget to cross-check the differential with the model of the car it is going to be installed in.
Driving Needs
Consider the driving habits and needs. For example, a limited-slip differential (LSD) works best for people who drive cars with a lot of power. This type of differential helps to transfer traction to the wheel that has the most traction. In simple terms, it supports the driver in maintaining control of the car.
Gear Ratio
The gear ratio of the differential should match the transmission and the engine performance. A well-matched differential gear ratio will enhance the performance of the great wall pickup parts and the overall driving experience. For example, a 3.55 ratio will have a smoother take-off than a 3.73 ratio.
Quality and Reliability
Spend more money on high-quality and long-lasting Great Wall car parts. This is because they will provide more comfort and pleasure during driving. With high-quality parts, one doesn't need to worry about replacement or repair anytime soon. Also, prioritize the quality of the differential. Look for reputable brands and high-quality materials to ensure durability and reliability.
Budget
Set aside money for purchasing a great wall differential. The amount of money to be used should be determined beforehand. Don't forget to consider the long-term costs, such as maintenance and repair, when budgeting for the differential. Always remember that the best quality differentials are more expensive but also more cost-effective in the long run.
Installation and Maintenance
Consider the installation and maintenance of the differential. For example, some models are easy to install, while others require professional installation, which attracts additional costs. Also, remember that some differentials require regular maintenance, such as lubrication or oil change, more than others.
Warranty and Support
Last but not least, ensure that the supplier or manufacturer offers a solid warranty and customer support. In case of any problems or defects, a reliable warranty and support can provide peace of mind and assistance.
There are no official instructions for replacing the Great Wall differential as each model has its own unique steps. However, some general steps are easy to follow. First, identify the model of the Great Wall car to get the right replacement kit. The replacement kit will have a user manual with instructions on how to install. Below are the steps to install a Great Wall differential.
Prepare
Great Wall Haval car owners should read the user manual to understand how to get the front and rear axles up. They should also know how to drain fluids from the differentials. Get all tools required for the job and work in a clean environment.
Remove the old differential
Lift the car and make it stable with jack stands. Disconnect all parts connected to the differential and drain all fluids. Unbolt the Great Wall differential and lift it out of the car.
Install the new differential
Great Wall car owners should refer to the installation manual to know how to unbox the new differential and prepare it. Mount the new differential carefully and bolt it up. Connect all parts that were disconnected during removal. Make sure the seals are tight to avoid leakage.
Great Wall pickups and other models that have four wheels should follow similar steps. If the new differential is pre-assembled, owners should follow manual instructions to install it. Once the new differential is in place, double-check all connections and bolts. Lower the car and test drive it to make sure everything is working well.
Q1: What is the function of a differential in a 4WD car?
A1: The differential is a critical part of the transmission system in a 4WD car. It evenly distributes torque to the wheels, allowing them to rotate at different speeds. This is especially important when making turns, as it prevents tire wear and maintains vehicle stability.
Q2: What are the different types of great wall differentials?
A2: Great wall differentials come in various types, each designed for specific needs. The open differential is the most common type and is found in many vehicles. The locking differential is ideal for off-road and low-traction conditions. The limited slip differential offers a middle ground between the other two types, providing more grip than an open diff without fully locking like a locker diff.
Q3: Can the differential be repaired, or does it always need to be replaced?
A3: It is often more cost-effective to replace the great wall differential rather than attempt to repair it, especially in severe damage cases. However, some differential parts, such as bearings and seals, can be repaired or replaced. A professional mechanic should assess the differential to determine the best course of action.
Q4: Does the type of great wall differential affect vehicle performance?
A4: Yes, the type of differential can impact a vehicle's performance. For example, a locking differential can improve traction in off-road conditions, while a limited slip differential can enhance cornering performance in sports cars. Choosing a differential type that suits the vehicle's intended use is essential.
