Axle Shaft Assembly: Description and Operation
Rear Axle
The rear axle assembly contains two rigid axle shafts which transfer engine torque to the rear wheels. These axle shafts (2) are supported in the rear
axle housing (1) by bearings (4) at both outer ends, and driven by the differential assembly which is mounted in the center of the rear axle housing. A
propeller shaft turns the differential assembly and transfers power to the rear axle shafts. The rear axle housing is sealed and contains a synthetic gear
lubricant which lubricates the differential assembly and axle shafts bearings.
The rear axle housing is also vented to prevent excessive heat buildup. The rear trailing rods connect the rear axle housing to the frame and act as
pivot points for the housing as it moves up and down with the rear suspension. Coil springs support the rear of the vehicle and are seated into the
frame and rear axle housing axle. Shock absorbers are fitted between the rear axle housing and the frame to help to reduce road vibration and rough
pavement. An upper control arm is fitted to the body by bushings, and to the rear differential carrier by a rear control arm ball joint to prevent the rear
axle housing from moving in a lateral direction.
