What are the five (5) functions of the drive axle assembly?
a) The drive axle assembly must withstand and support the weight of the vehicle
and load
b) The drive axle assembly provides a gear reduction in the basic vehicle
powertrain.
c) The drive axle assembly must change the direction of torque by 90°.
d) The drive axle must transfer torque evenly between the two wheel assemblies
e) The operator is able to lock the wheel ends in a low traction situation.
The main function of the carrier housing is to
hold the internal gear components.
The pinion bearing cage is always a removable component of the carrier housing.
false;
The overhung pinion differs from the straddle mount in that it has a short stub that
extends past the end of the pinion gear.
false;
The input drive pinion is in constant mesh with the:
bevel gear.
What is the main purpose of the thrust screw?
The thrust screw prevents the bevel gear from deflecting away from the input pinion
during heavy torque loads.
The bevel gear is bolted directly to the:
flanged case half.
The differential pinions are driven by the:
cross shafts.
The most common differential carrier assembly used today is the:
single speed single reduction.
Which components are attached to the drive axle housing?
all of the above
Number the following components in the path-of-power through the single speed,
single reduction carrier assembly. Begin with the input shaft yoke and end with the
wheel assemblies.

The torque available to the wheel with good traction in a wheel spin condition is:
the same as the torque to the spinning wheel.
When a vehicle is turning a corner, the differential assembly allows the:
outer drive wheel to rotate faster than the inner drive wheel.
Semi-floating axle shafts can be removed from a vehicle when the weight of the vehicle is on the drive wheels.
false;
Transfer cases always incorporate a differential to allow for a difference in speed
between the two output shafts
