4.
Disconnect propeller shaft at rear axle companion
flange.
5.
Support differential on portable floor jack and take off
U-bolts.
6.
Roll out axle from under truck.
Axle Shaft
The axle shafts can be removed without taking off the wheels.
To remove the shafts, first remove the axle shaft nuts from the
studs in the wheel hub. Next install puller screws in the two
tapped holes provided in the axle shaft flange. As puller
screws are turned in, flange of shaft will be forced away from
wheel hub and out from axle housing.
Another type of axle shaft removal procedure is required on
full-floating axles where the tapered dowel is used in addition
to the studs and nuts for securing axle shaft flange to wheel
hub. This procedure will be similar to the following:
1.
Remove flange nuts from studs of wheel hub.
2.
Using a heavy hammer, strike sharply on the center
of the flange of the axle shaft, Fig. 6, This will unseat
and loosen the tapered dowels in each stud hole.

3. Remove the tapered dowels, Fig. 7.
NOTE:
When dowels are installed, there must be a
slight clearance between the lockwasher and
axle shaft driving flange. See inset, Fig. 7.
Lack of clearance at this point will cause
excessive wear on studs, dowels or holes.

4. After all dowels have been removed, push the axle shaft
flange back into position against the wheel hub and again
strike a sharp blow in the center of the flange as shown in
Fig. 6. This will cause the axle shaft to spring away from
the wheel hub and allow removal of the axle shaft without
resorting to the use of a pry bar or screwdriver. Any
prying between axle shaft flange and wheel hub may
damage the seal assembly or machined surfaces of the
wheel hub or axle shaft flange.

screw is to be kept with axle at all times.)
Differential
To remove the differential on some axles, it may be necessary
to use the two extra tapped holes found in the differential
housing. These are for installing puller screws, Fig. 8. To
