Diff Case & Diff Carrier

Differential is a differential gearing device that transmits the power of the
transmission output to the wheels.
It is a part that allows the rotation of the left and right wheels of the car to be
changed smoothly on uneven roads and when turning. And when the vehicle turns,
the inner wheel feels resistance and the number of rotations decreases compared
to the outer wheel, and when the number of rotations decreases, the pinion gear
of differential assembly rotates to increase the speed of the outer wheel
to enable smooth driving.
