Brass Drift Method:
WARNINGS
To prevent serious eye injury, always wear safe
eye protection when you perform vehicle
maintenance or service.
WARNING
Do not strike the round driving lugs on the flange
of an axle shaft. Pieces can break off and cause
serious personal injury.
NOTE:
A 1.5-inch (38.1 mm) diameter brass
hammer can be used as a drift.
a. Hold a 1.5-inch (38.1 mm) diameter brass
drift against the center of the axle shaft
flange, INSIDE THE ROUND DRIVING LUGS.
Figure 2
.
b. Hit the end of the drift with a large hammer
(5 to 6 pounds, 2.3 to 2.7 kg) to loosen the
axle shaft and tapered dowels from the hub.

Air Hammer Method:
WARNINGS
To prevent serious eye injury, always wear safe
eye protection when you perform vehicle
maintenance or service.
a. Use an air hammer, such as Chicago
Pneumatic CP-4181-PULER, or equivalent,
with a round hammer bit to loosen the axle
shaft and dowels.
b. Put the round hammer bit against the axle
shaft flange between the studs, at different
points around the flange. Operate the air
hammer at each location and loosen the
axle shaft and tapered dowels from the hub.
Figure 3
.
7.
Identify each axle shaft that is removed from
the axle assembly so they can be installed in
the same location after transporting or repair is
completed. (Example: Match mark a mating
axle shaft and hub.)
8.
Remove the tapered dowels, gasket (if used)
and the axle shaft from the axle assembly.
Figure 1
.
9.
Install a cover over the open end of each hub
where an axle shaft was removed. This will
prevent dirt from entering the bearing cavity
and loss of lubricant.
NOTE:
If an air supply will be used for the brake
system of the transported vehicle, continue with
Steps 10 and 11, otherwise continue with Step 12.
10. Connect an auxiliary air supply to the brake
system of the vehicle that is being transported.
Before moving the vehicle, charge the brake
system with the correct amount of air pressure
to operate the brakes. Refer to the instructions
supplied by the manufacturer of the vehicle for
procedures and specifications. If an auxiliary
air supply is not used, continue with Step 12.
11. When the correct amount of air pressure is in
the brake system, release the parking brakes of
the vehicle that is being transported. Step 12 is
not required.
WARNING
When you work on a spring chamber, carefully
follow the service instructions of the chamber
manufacturer. Sudden release of a compressed
spring can cause serious personal injury.
12. If there are spring (parking) brakes on the
axle(s) that will remain on the road when the
vehicle is transported, and they cannot be
released by air pressure, manually compress
and lock each spring so that the brakes are
released. Refer to the manufacturer’s
instructions.
