What is a Diff and What Does It Do?

A differential, known as a diff for short, is part of every drivetrain.

The root of a diff is a set of hardened steel gears. This then direct power from the engine and transmission to the wheels.

With a transaxle, commonly used on a front-wheel-drive car, the diff is integral were-as. For a rear-wheel-drive or 4WD vehicle, the differential is a separate component.

Its purpose is two-fold: to change the direction of torque heading to the drive wheels. This allows for drive wheels to turn at different speeds.

All of an engine’s torque goes into a single transmission or transaxle. This needs to be directed to two wheels.

Differential side gears mesh with the larger pinion gear to perform that function.Spider gears allow for one wheel to turn faster than the other. Preventing binding and wheel scuff when you’re taking a corner.
