The following method is to be used to ensure
that axle shaft installation is fluid-tight:
FIGURE 8: AXLE SHAFT INSTALLATION
1 .................................................... Silicone sealant*
2 .............................................................. Axle shaft
3 ................................................................... Gasket
4 ............................................................. Wheel hub
1. Clean the mounting surfaces of both the axle
shaft flange and wheel hub where silicone
sealant will be applied. Remove all old
silicone sealant, oil, grease, dirt and moisture.
Dry both surfaces.
2. Apply a continuous thin bead of silicone
sealant* (Prevost P/N 680053) on the
mounting surfaces and around the edge of all
fastener holes of both the axle shaft flange
and wheel hub.

GENERAL ELECTRIC Silicone Rubber Adhesive Sealant
RTV 103 Black.
WARNING
Carefully read cautions and instructions on the
tube of silicone sealant and its packing.
3. Assemble components immediately to permit
the silicone sealant to compress evenly
between parts.
a. Place a new gasket and then install the
axle shaft into the wheel hub and
differential carrier. The gasket and flange
of the axle shaft must fit flat against the
wheel hub.
b. Install the tapered dowels at each stud
and into the flange of the axle shaft. Use
a punch or drift and hammer if needed.
c. Install the lock washers and nuts on the
studs. Tighten nuts to the correct torque
value.
NOTE
Torque values are for fasteners that have a light
application of oil on the threads (refer to Meritor
Maintenance Manual).
