Operation

The rear axle operates as follows:

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