Where Is the Differential on a Car?

While many drivers know the importance of an oil change, there aren’t as many familiar with differential service. That can come with many questions, such as “Where is the differential on a car?” North Penn Volkswagen provides a closer look.

What Is a Differential?

Vehicles are equipped with a differential, which is a specialized gearbox. It’s designed to transfer engine power to your wheels, while still allowing the wheels to spin at different speeds.

When driving straight, both wheels rotate at the same speed. However, as you turn, your outside wheels have a longer distance to cover than your inside wheels. The differential allows the outside wheels to spin faster, which helps to provide smooth cornering.

What Types of Differentials are There?

There are four main types of differentials:

• Open: The most common differential type, which gives power to both wheels, while splitting the torque evenly.
• Limited-Slip: If slippage is detected, it uses clutches or gears to redirect power to the wheel with the most grip.
• Locking can automatically (or manually) lock both wheels so they spin at the same speed. This is typically used for off-roading.
• Torque-Vectoring uses sensors and computers to send varying amounts of torque to individual wheels to enhance stability.

Where Is It Located?

The location of your differential depends on what type of drivetrain you have. In a FWD vehicle, for example, the differential is typically part of your transmission.

RWD vehicles house their differential in a metal casing between the rear wheels. AWD vehicles (or 4WD vehicles) have front and rear differentials, as well as a center differential that is often bolted to the back of the transmission.
