19c. Re-install the shims in their original locations
on the bevel gear shaft.
19d. Smear some Durina
of the shaft that will ride in the flange bearings.
19e. Install new bevel gear shaft bearings, with
their flanges facing the shims.
See Figure 5.78.
NOTE: The bevel gear shaft bearings are of differ-
ent lengths.
The longer bearing goes on the reduction gear end of
the shaft. The shorter bearing goes on the brake-spline
end of the shaft.
19f. Install the brake shaft seal. The primary pur-
pose of this seal is to keep grease away from
the brakes. The seal should be installed with
the lip facing in.
19g. Install the bevel gear shaft into the transmis-
sion housing for a dry fit check.
20. Install the axle and differential assembly:
20a. Check notes, markings, or witness marks on

positions.
20c. Apply a small amount of Durina
the in-board bearing contact surfaces of the
axle, then slide new bearings into place.

the outer bearing contact surfaces of the axle,
then slide new bearings into place.
20e. Slip the seals onto the axle shaft. The seal lip
should face outward.
