How many differentials does a AWD have?
As the owner of Kevin's Autos, I often encounter questions about the intricacies of vehicle mechanics. One common inquiry pertains to the number of differentials found in all-wheel drive (AWD) systems. This article aims to clarify this topic and provide insights into the role of differentials in AWD vehicles.
What is a Differential?
A differential is a crucial component in a vehicle's drivetrain that allows for the difference in wheel speed between the left and right wheels. This is particularly important when a vehicle turns, as the outside wheels travel a longer distance than the inside wheels. In AWD systems, differentials play a vital role in distributing power to all four wheels effectively.
How Many Differentials Does an AWD Have?
Typically, an all-wheel drive vehicle will have two to three differentials. Here’s a breakdown:
- Front Differential: This differential is located at the front axle and allows the front wheels to rotate at different speeds, especially during turns.
- Rear Differential: Similar to the front, the rear differential is found at the back axle and serves the same purpose for the rear wheels.
- Center Differential: Many AWD systems also include a center differential, which distributes power between the front and rear axles. This component is essential for maintaining traction and stability across all four wheels.
Types of Differentials in AWD Systems
AWD vehicles may utilize different types of differentials, including:
- Open Differential: This is the most common type, allowing for free rotation of wheels but can lead to traction loss if one wheel slips.
- Limited-Slip Differential: This type helps to transfer power to the wheel with more traction, improving stability and control.
- Locking Differential: This differential can be locked to ensure both wheels on an axle turn at the same speed, which is beneficial in off-road conditions.
Conclusion
Understanding the number and function of differentials in AWD vehicles is essential for any car owner. With typically two to three differentials, these components work together to enhance traction, stability, and overall driving performance.

Frequently Asked Questions
Does AWD have a center differential?
Vehicles with full-time AWD have a center differential that allows each wheel to turn at different speeds when turning corners. This system is versatile for different roads, and the center differential can be locked manually or automatically when traction is low.
Do AWD cars have 2 differentials?
AWD cars will normally come with three differentials. There's one for the front wheels that allows them a slip, but not necessarily a differential slip. Then there's one for the back wheels that does the same, and then the center differential that mediates the two.
Can you drive AWD without front differential?
A vehicle with all-wheel drive AWD or four-wheel drive 4WD can still move without the front driveshaft, but it will only be front-wheel drive. This is because the front wheels are still connected to the engine through the transmission.
What is the difference between a rear axle and a differential?
Some use “rear axle” as a term for the complete assembly from wheel to wheel, including both axles (properly “axle shafts”), differential assembly and sometimes even the brakes (which also are at each end of the axles). Others call it simply “the differential” or “diff”.
Does a 2 wheel drive have a rear differential?
Traditional two-wheel drive systems have a differential in the rear axle.
Does 4WD have front and rear differential?
The main parts of any four-wheel-drive system are the two differentials (front and rear) and the transfer case. In addition, part-time systems have locking hubs, and both types of systems may have advanced electronics that help them make even better use of the available traction.
How many axles does AWD have?
How many axles does a 4-wheel drive have? There are typically two axles in a four-wheel drive: a front axle and a rear axle. The drivetrain is connected to both the front and rear axles. Due to the power being distributed to all four wheels, the car's traction and stability are improved.
Do AWD cars have 4 CV axles?
All Wheel Drive vehicles have four CV Axle Shafts, two connecting the transmission to the front wheels, and two more connecting the rear differential to the rear wheels. The CV Joints allow for the axle to continue to spin while the suspension moves in response to the road and driver inputs.
Does AWD have 3 differentials?
AWD cars will normally come with three differentials. There's one for the front wheels that allows them a slip, but not necessarily a differential slip. Then there's one for the back wheels that does the same, and then the center differential that mediates the two.
Does AWD have two differentials?
4WD normally has 2 differentials, while AWD can have up to three. The main difference in differential repair comes down to how easily each differential component is to access and make the the repair.
