Components of the Rear Steering (1) Final Drive (3) Tie rods (6) Steering Cylinder assembly (8) Kingpins (9) Knuckle assemblyThe hydraulic steering cylinder assembly (6) is connected to the knuckle assemblies (9) through two adjustable tie rods (3). The knuckle assemblies (3) rotate on the axle with opposing tapered roller bearings in the kingpins (8) .Differential
Power from the transmission output shaft is transferred to the front axle by the drive shaft and universal joints. The power enters the front axle through the input flange. The input flange is attached to the pinion gear. Power is transferred from the pinion gear to the differential ring gear. The differential ring gear is bolted to the differential .Power is transferred through the differential by the pinion gears to the side gears. The side gears are splined to the axle shafts. Refer to Systems Operation, "Differential" for more information about the differential.Service Brakes
Illustration 3 g01201638
The rear axle contains the service brakes. The counterplates (18) of the brake connect to the brake housing (5) by three reaction pins. The friction discs (19) are splined to the carrier (21). The carrier (21) is splined to the axle shaft (11). When the brakes are applied, the brake pistons (20) push the brake plates against the friction discs. This causes friction. The friction causes the wheels to turn at a slower rate or stop. The brake piston is held in place by the pins. When the brake pedal is released, the springs on the pins force the brake piston away from the brake plates. This releases the brakes on the axle.Final Drives

Components of the Final Drive and Axle (2) Flange (11) Axle shaft (12) Universal joint (13) Carrier (14) Sun gear and shaft (15) Planetary gears (16) Ring gear (17) HousingThe power is transferred through the axle shaft (11) and the universal joint (12) to the final drive. The final drive causes the last speed reduction and the last torque increase in the drive train. The final drive consists of the following components: the sun gear (14), the carrier (13), the planetary gears (15), and the ring gear (16). The sun gear (14) is joined to the axle shaft (11) by the universal joint (12). The ring gear (16) is splined to the housing (17). Three planetary gears (15) are mounted in the carrier (13). The carrier (13) is bolted to the flange (2). The flange (2) rotates
