When semifloating axles are used to drive the vehicle,
the axle shafts push on the shaft bearings as they rotate.
This places a driving force on the axle housing, springs,
and vehicle chassis, moving the vehicle forward. The axle
shaft faces the bending stresses associated with turning
corners and curves, skidding, and bent or wobbling
wheels, as well-as the weight of the vehicle. In the semifloating
axle arrangement with C-shaped washer-type
retainer if the axle shaft breaks, the driving wheel comes
away from or out of the axle housing.
