The output shaft system consists of the output shaft gears, differential ring (final drive) gear and the differential assembly. Typically when a vehicle is traveling down the road both wheels are rotating at the same speed; however, when a vehicle is turning, the outside wheel must travel a greater distance than the inside wheel. To do this, in the same time, the outside wheel must rotate faster than the inside wheel. The differential is designed to provide speed compensation for the wheels to allow the vehicle to negotiate turns smoothly.
