Do subarus have a front and rear differential?
Subarus are renowned for their all-wheel-drive (AWD) systems, which provide excellent traction and stability in various driving conditions. A common question among Subaru owners and enthusiasts is whether these vehicles are equipped with both front and rear differentials. In this article, we’ll explore the role of differentials in a vehicle and explain how they function in Subarus.
Understanding Differentials in Vehicles
A differential is a crucial component of a vehicle's drivetrain. Its primary function is to allow the wheels on the same axle to rotate at different speeds, which is essential when turning. Without a differential, the wheels would be forced to spin at the same speed, leading to increased tire wear and difficulty maneuvering.
In vehicles with AWD or four-wheel drive (4WD) systems, there are typically multiple differentials to manage power distribution between the front and rear wheels, as well as between the left and right wheels on each axle.
Subaru's All-Wheel-Drive System
Subarus are equipped with a symmetrical AWD system, which is a hallmark of the brand. This system ensures power is distributed evenly to all four wheels, enhancing traction and stability. To achieve this, Subarus are designed with both front and rear differentials, as well as a center differential or a similar mechanism, depending on the model and transmission type.
Front and Rear Differentials in Subarus
Yes, Subarus have both front and rear differentials. Here’s how they work:
- Front Differential: Located at the front axle, the front differential manages the power sent to the front wheels, allowing them to rotate at different speeds when needed, such as during turns.
- Rear Differential: Positioned at the rear axle, the rear differential performs the same function for the rear wheels, ensuring smooth and efficient operation.
In addition to these, Subarus with AWD systems also feature a center differential or a similar mechanism (such as a viscous coupling or an electronic system) to manage power distribution between the front and rear axles. This setup is what gives Subarus their exceptional handling and performance in various driving conditions.
Why Are Differentials Important?
The presence of front and rear differentials in Subarus is vital for several reasons:
- Improved Handling: Differentials allow the wheels to rotate at different speeds, ensuring smooth turns and better control.
- Enhanced Traction: By distributing power effectively, differentials help maintain grip on slippery or uneven surfaces.
- Reduced Wear and Tear: Proper power distribution minimizes strain on the drivetrain and reduces tire wear.
Conclusion
Subarus are equipped with both front and rear differentials as part of their symmetrical AWD system. These components play a critical role in ensuring the vehicle's performance, safety, and reliability. Whether you're navigating snowy roads or taking sharp turns, the differentials in your Subaru work seamlessly to provide a smooth and controlled driving experience.

Frequently Asked Questions
Do subarus have front differentials?
All-wheel drive Subarus have both front and rear differentials. The fluid in the differential system breaks down over time and will eventually need to be replaced.
Do subarus have a limited slip differential?
At the core of our legendary symmetrical-full-time AWD system is Subaru's centre limited-slip differential.
Do subarus have two differentials?
Viscous Center Differential (VCD)
This VCD system is used on all manual transmission models, like the Crosstrek, Impreza, and Forester. The torque is split 50/50 between the front and rear wheels and includes an open front and rear differential.
What is front and rear differential service Subaru?
Subaru Front & Rear Differential Service
Your differential is what translates rotational power from the engine to the axles. Since your Subaru is an all-wheel drive vehicle, keeping the front, middle and rear differentials well lubricated is essential to its performance and health.
Do AWD cars have limited slip differentials?
Sometimes there is a switch or level to turn off the AWD, but unlike 4WD they are perfectly at home on dry pavement while sending power to both axles. This is accomplished with a center differential, and often one that operates with limited slip properties.
Does AWD have two differentials?
Some AWD vehicles have 2 differentials — one on each axle — but instead of a center differential they have some sort of clutch system that can variably engage and disengage to control the amount of torque sent to each axle (e.g. Volvo's Haldex system).
Is there a front and back differential?
Each vehicle's differential system is different and based on the wheel drive of your car. A car with front-wheel drive is equipped with a front differential, while all-wheel drive and four-wheel drive vehicles utilize both front and rear differentials to direct power to all four wheels.
How often to change Subaru rear differential fluid?
When Should Differential Fluid Be Changed? Fortunately, differential fluid doesn't need to be changed as often as the oil in your engine, but we do recommend that you get your differential fluid replaced every 15,000 miles or so.
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.
Is there a front differential in AWD?
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.
