11. Before pressing pinion out of housing:
If unit was equipped with an expansion plug (re-
mo
ved in step 10), remove the snap ring and shim
from the end of the pinion (Fig. 29).
If unit is equipped with a flange for 4WD (no expan-
sion p
lug), nut, washer and flange (Fig. 3C) must be
removed before pressing pinion out of housing.
Figure 29
12. Position the housing assembly on a suitable press.
Place a 1/8 inch (3 mm) piece of steel or a screwdriver
blade under the edge of the spur gear. This will prevent
the spur gear from cocking and possibly cracking the
housing (Fig. 30).
When the pinion is close to being pressed completely
ou
t of the bearing, reach under the housing and catch
the pinion in your hand to prevent any damage to the
pinion.

Removing the drive pinion releases the spur gear,
spacer, and outer pinion bearing for removal (Fig. 31).
If unit was equipped with a flange for 4WD (no expan-
sion plug), remove oil seal from housing (Fig. 3B).
