Operation

• Rear axle drive pinion receives power from the engine through the transmission and driveshaft (4602)
• Pinion gear rotates differential case (4204) through engagement of ring gear which is bolted to the differential case .
• Inside the differential case , two differential pinion gears (4215) are mounted on the differential pinion shaft (4211) .
• The differential pinion shaft is pinned to the differential case .
• The differential pinion gears are engaged with differential side gears (4236) .
• Differential side gears are splined to the axle shafts (4234) .
• As differential case turns, it rotates the axle shafts and wheels (1007) .
• When it is necessary for one wheel to rotate faster than the other, the faster turning differential side gear causes the differential pinion gear to roll on the slower differential side gear to allow differential action between the two axle shafts .
