Are all Subaru differentials the same?

Are all Subaru differentials the same?
No, all Subaru differentials are not the same. Subaru vehicles have different differentials for various models, each designed to improve grip, turning capability, and overall safety. These systems include Viscous Center Differential (VCD), Active Torque Split (ATS), Variable Torque Distribution (VTD), and Driver Controlled Center Differential (DCCD). The specific type of differential used can vary depending on the model and transmission type. For example, cars with continuously variable transmissions (CVT) receive a specific type of system, while those equipped with a manual transmission use a different setup. Additionally, there are separate systems for the WRX and WRX STI models. Subaru integrates their transfer case directly into the transmission, which is different from most other brands that use a separate section for the transmission and transfer case. Overall, Subaru employs various differential systems tailored to different models and transmission types to optimize performance and handling in different driving conditions.

Can you replace just a differential?

A differential replacement is somewhat easier than a differential rebuild, but since it involves replacing everything at once, it’s going to be quite an investment.

Do Subarus have a limited slip differential?

The front axle offers a Helical limited slip differential while the rear holds a Torsen limited slip differential.

How often do differentials need to be replaced?

Over time, the differential fluid gets dirty, breaks down, and needs to be replaced. So, it is necessary to have your differential serviced regularly. It is recommended to have the differential fluid changed every 40,000 to 60,000 miles.

How many differentials do Subarus have?

There’s a gearbox between the drive wheels of your new Subaru. If it’s an all-wheel-drive system, then you’ll nearly always have a front and rear differential. This gearbox works with your vehicle’s transmission to send power from the engine to the wheel’s axle, which stabilizes your vehicle’s turning.

Do Subarus have 3 diffs?

Subaru uses a fairly conventional full-time four-wheel drive system with three differentials. The centre diff splits torque between the front and rear axles, and the axle differentials divide it again between left and right. So nominally each wheel gets 25% of the overall torque.

What is the diff ratio for a Subaru?

Subaru used 3.9:1, 4.111:1, 4.444:1 diff ratios and 1:1 and 1.1:1 drop gear ratios, mix them up and you will break something.

What kind of differential does a Subaru have?

But basically you’ve got your engine sending power to the transmission. Then sending it to a planetary style. And mechanical limited slip differential.

What is the rear diff ratio for a Subaru?

These gears are a multiplier only for the rear diff ratio. Subaru uses only 1.0 or 1.1 ratios for the transfer gears depending on the application. The 1.1 ratio has been used with certain applications using a 3.90 final drive ratio. With the 1.1 transfer ratio a 3.545 rear diff ratio is used (3.545 x 1.1 = 3.90).

Are all Subaru AWD systems the same?

Every model in the Subaru lineup except the Subaru BRZ comes standard with an AWD system. While the type of AWD system may vary slightly between models, they all come equipped with it.

Are all differentials the same?

Connecting the wheels together, a differential takes power from the engine and sends it to the wheels. Different types control how much or little power makes it to the wheels. There are four common types of differentials on the market – open, locking, limited-slip and torque-vectoring.
