shaft as shown in Fig. 25. Use
a 0.0015-inch feeler gauge between
the bearing and the pinion gear to
be sure that the bearing is fully
seated.
5. After determining the correct
shim thickness and insta11ing the
rear bearing as explained in the fore-
going steps, install the new pinion
and ring gear as outlined under "As-
sembly."
DIFFERENTIAL CASE,
BEARINGS, AND RING GEAR
If the ring gear runout check be-
fore disassembly exceeded specifi-
cations, the condition may be caused
by a warped ring gear, a defective
case, or by excessively worn differ-
ential side bearings.
To determine the cause of exces-
sive runout proceed as follows:
1. Remove the ring gear from the
case, and install the case back in the
housing with side bearings and cups
still installed.
2. Check the runout of the case
flange with a dial indicator. If the
runout does not now exceed speci-
fications, install a new ring gear to
the case during assembly. If the run-
out still exceeds specifications, the
ring gear is true and the trouble is
due to either a defective case or
worn bearings. Continue with steps
3 through 5.
3. Remove the differential case
from the carrier housing and re-
move the side bearings from the
case, using the tool shown in Fig. 21.
4. Press new bearings on the case
hubs with tool 4222-H, and again
install the differential case assembly
in the housing without the ring gear.
5. Check the case runout again
with the new bearings. If the runout
is now within specifications, the old
bearings were excessively worn. Use
new bearings for assembly. If the
runout is still excessive, the case is
defective and should be replaced.

ASSEMBLY
1. Place a thrust washer over
each pinion and side gear. Assemble
the pinion and side gears in the
differential case and secure them
with the pinion shaft (Fig. 6, Part
4-1). Lubricate all differential
parts liberally with axle lubricant
during assembly.
2. Slide the side gears and thrust
washers tightly against the pinion
gear. Then, using a feeler ribbon,
check the clearance between the case
and the thrust washers. If the clear-
ance exceeds 0.015 inch, new thrust
washers must be installed.
3. Align the lock pin hole in the
pinion shaft with the hole in the case
and install the lock pin. Peen the
case metal over the lock pin.
4. Place the differential case as-
sembly in a holding fixture, tool
4205-B. Install the ring gear and
secure it with bolts. Torque the bolts
to specifications.

DIFFERENTIAL
CASE ASSEMBLY
1. Select the side gear ring and
the clutch pack that pertains to the
ring gear half of the differential
case (Fig. 26). Assemble to the side
gear ring in order: a flat clutch
plate (with external lugs), a clutch
disc (with internal splines), a clutch
plate, the spring disc (with convex
side toward the case), and the
spring plate (with convex side to-
ward the case) .
2. Assemble the remaining clutch

plates and discs to the side gear that
pertains to the cover half of the case.
Follow the same order of assembly
as in the foregoing step.
3. Hold each differential case half
on its side and install the pertinent
side gear ring with plates and discs
assembled. Make sure that the
dutch plate lugs are aligned and
that they enter the slots in the case
(Fig. 27). The side gear ring will
rotate with a slight drag when
properly seated in the case.
4. With the ring gear half of the
case in an upright position, as in
Fig. 28, place the proper side
gear on the side gear ring. Place the
lower (ring gear half) mate shaft
and pinions on the side gear ring
so that the locating marks on the
