3.
Meritor axle:
Loosen the tapered dowels in the
flange of the axle shaft using the following
methods.
a) Do not strike the round driving lugs on the
flange of an axle shaft. Pieces can break off
and cause serious personal injury. A 1.5-inch
(38.1 mm) diameter brass hammer can be
used as a drift.
b) Hold a 1.5-inch (38.1 mm) diameter brass drift
against the center of the axle shaft flange,
inside the round driving lugs.
c) Hit the end of the drift with a large hammer (5
to 6 lbs.’) to loosen the axle shaft and tapered
dowels from the hub.
4. 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).

5. Remove the tapered dowels (if used), gasket or O-ring and the axle shaft from the axle assembly.
Use a container to recover the oil.
6. Remove opposite flange shaft similarly.
7. Install a temporary 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.
After Towing
1. Remove the covers from the hubs.
2. Install the gasket or O-ring, and axle shaft into the axle housing and carrier in the same location it
was removed from. The gasket and flange of the axle shaft must be flat against the hub. Rotate the
axle shaft and/or the driveline as necessary to align the splines and the holes in the flange with the
studs or holes in the hub.
3.
Meritor axle only:
Install the dowels over each stud and into the tapered holes of the flange.
4. Install the washers and stud nuts or cap screws.

Determine the size of the fasteners and tighten the nuts to the
corresponding torque value shown below.
Tightening torque M18x1.5 G10.9 screw
9/16-18 plain nut: 110 - 165 lbf-ft (149-224 Nm)
5/8-18 plain nut: 150 - 230 lbf-ft (203- 312 Nm)
325 lbf-ft (440 Nm)
5. Mount opposite flange shaft similarly.
6. Inspect the lubricant level in the axles and hubs where the axle shafts were removed. Add the correct
type and amount of lubricant if necessary.
CAUTION
Make sure axle shafts or driveshaft are installed correctly after towing. Tighten axle shaft and
driveshaft nuts to the correct torque settings. Do not invert shafts.
