The differential also contains two side gears. The in side bore of the side gears is spline and mates with
splines on the ends of the axles. The differential pinion gears and side'gears are in constant mesh. The pinion gears
are mounted on a pinion gear shaft, which is mounted in the differential casing. As the casing tums with the ring gear, the pinion shaft and gears also tum. The pinion gears deliver torque to the side gears.
