(24) Use an appropriate tool to force the drive p i n -
i o n gear shaft ( w i t h the rear bearing) from the dif-
ferential housing bore (Figs. 1 a n d 2).
(25) Use Removal Tool D-158 and Handle Tool C-
4171 to remove the drive p i n i o n gear shaft f r o n t
bearing cup f r o m the differential housing bore (Figs.
1 and 2).
(26) For Model 60 and 6 0 M axles, use Removal
Tool D-162 and Handle Tool C-4171 to remove the
drive p i n i o n gear shaft rear bearing cup from the dif-
ferential housing bore (Fig. 1). For Model 70 axles,
use Removal Tool D-159 and Handle Tool C-4171 to
remove the drive p i n i o n gear shaft rear bearing cup
from the differential housing bore (Fig. 2).
(27) Remove the drive p i n i o n gear depth shims
from the differential housing bore (Figs. 1 and 2).
Record the thickness of the depth shims.
(28) Remove the rear bearing f r o m the drive p i n i o n
gear shaft w i t h Removal Tool DD-914-P,
Adapter
R i n g Tools DD-914-9 and Plate Tools DD-914-37. Use
Plate Tools DD-914-95 for Model 70 axles.
(29) For Model 60 and 6 0 M axles, clamp the differ-
e n t i a l case i n a vise equipped w i t h soft jaws. Use a
p i n punch to force the p i n i o n gear mate shaft lock
p i n from the differential case bore (Fig. 8). For Model
70 axles, m a r k the differential case halves (Fig. 9)
for assembly reference; remove the studs r e t a i n i n g
the differential case halves together; and separate
the differential case.
(30) Remove the differential p i n i o n gear mate shaft

from the differential case bores, remove the differen-
t i a l pinion gears and remove the t h r u s t washers (lo-
cated
adjacent
to
the
differential
case i n t e r n a l
surface) from the differential case.
(31) Remove the differential side gears and the
t h r u s t washers (located adjacent to the differential
case i n t e r n a l surface) from the differential case.
(32) Remove the differential case from the vise.

(34) Remove the differential bearing shims from
each of the differential case hubs and m a r k t h e m
( w i t h hub i d e n t i t y ) for assembly reference. Record
the thickness of t h e shims.
CLEANING/INSPECTION
(1) Wash and clean a l l the differential components
(Figs. 11 and 12) w i t h an appropriate cleaning sol-
vent and, w i t h the exception of the bearings,
d r y
w i t h compressed a i r .
