The spider gears consist of 2 pinion gears and 2 differential side gears. The pinion gears turn on the pinion shaft, which is fitted to the inside of the differential case. The differential side gears are splined to the axle shafts and mesh with the pinion gears. When the vehicle travels straight ahead, the pinion rotates with the differential case and all gears rotate as a unit, transferring motion to the drive axles. However, when the vehicle turns, the inside wheel turns more slowly than the outside wheel, so the pinion gears then rotate on the pinion shaft, turn on the slower turning axle and drive the outside axle at a greater speed.
