Drew’s Garage installs and repairs all differentials.

The differential is a device that splits the engine torque two ways, allowing each output to spin at a different speed.

The differential is found on all modern cars and trucks, and  in many all-wheel-drive (full-time four-wheel-drive) vehicles. These all-wheel-drive vehicles need a differential between each set of drive wheels, and one in between the front and  back wheels as well, because the front wheels travel a different distance through a turn than the rear wheels.
