Remove the wheels and tires
from the brake drums.
3.
Position a drain pan and loosen
the rear axle cover to housing attach-
ing bolts. Drain the housing.
4.
Remove the attaching (Tinner-
man) nuts that secure the brake drums
to the axle shaft flanges, and then re-
move the drums (Fig. 7).
5.
Remove the axle housing cover
bolts,
cover and gasket. Discard the
gasket. Remove the drain pan.
6. Disconnect the drive shaft at the
drive pinion companion flange. Re-
move the drive shaft from the trans-
mission extension housing. Install an
oil seal replacer tool in the transmis-
sion housing to prevent leakage. Refer
to the transmission group for the ap-
propriate tool.
7.

shock absorbers at the mounting
brackets.
8. Disconnect the track bar from
the axle housing stud. If the axle
housing is to be replaced, transfer the
stud to the new housing.
9. Position safety stands under the
rear frame members. Lower the vehi-
cle with the hoist and allow the axle
to lower far enough to relieve rear
spring tension.
10.
Remove the pinion shaft lock
bolt and pinion shaft (Fig. 2), differ-
ential pinion gears and thrust washers.
11.
Push the axle shaft(s) inward
toward the center of the axle housing.
Remove the C-locks from the inner
ends of the axles (Fig. 3). Remove the
axle shafts from the housing. Extreme
care must be used to avoid contacting
the axle shaft seal lip with any portion
of the axle shaft other than the seal
journal.
12.
Disconnect the vent hose from
the rear vent tube and remove all
brake lines from the axle housing re-
taining clips.
13.
Remove the brake backing
plate attaching nuts and the plates
from the axle housing. Suspend the
plates above the axle housing with
mechanics wire. The hydraulic brake
lines and the parking brake cables will
remain attached to the brake backing
plates.
14.
Support the rear axle housine
on a jack.
15.
Remove the right and left rear
springs and insulators.
16.
Remove the nuts, washers and
pivot bolts that connect the suspension
lower arms to the axle housing. Dis-
connect both arms from the axle
housing.
17.
Disconnect the upper suspen-
sion arm from the axle housing by re-
moving the pivot bolt, nut, lock wash-
er and two eccentric washers.
18.
Lower the rear axle to the floor
with the jack and remove the axle
from under the vehicle.
19.
Remove the wheel bearings and
oil seals with the tool shown in Fig. 4.
20.
If the axle housing is being re-
placed, transfer all the differential and
pinion parts to the new housing. Refer
to Section 4, Major Repair Operation
for the procedure.
INSTALLATION
1.
Lightly coat the wheel bearing
rollers with axle lubricant. Install
wheel bearings in the axle housing
with the tool shown in Fig. 5. The
bearings should seat firmly against the
shoulder.
2.
Wipe all lubricant from the oil
seal bore before installing the seal. If
axle housing is being replaced, new
seals must be installed.
3.
Inspect the original seal for
nicks,
scuffs or abnormal wear, and
replace if necessary. New seals are
pre-packed with lubricant and do not
require an oil soak.
4.
Install the seal with the tool
shown in Fig. 6. Installation without
the use of the proper tool will distort
the seal and cause leakage.
5. Raise the rear axle into position
under the vehicle with a hoist or floor
jack. Connect the suspension lower
arms to their mounting brackets on
the axle housing with pivot bolts and
nuts.
Do not tighten the mounting
bolts at this point.
6. Position the suspension upper
arm in its mounting bracket on the
axle housing and install the adjusting
bolt, eccentric washers, lock washer
and nut. Do not tighten the mounting
bolt at this point.
7.
Place the rear coil springs and
insulators into position in the pockets
provided.
8. Place the brake backing plates
on the axle housing flanges, install 4
attaching bolts and nuts and torque
them to specifications.
9. Position the brake lines to the
axle housing and secure them with the
retaining clips. If the axle housing is
new, install a new vent. When install-
ing the new axle vent apply a small
amount of Locktite (C5AZ-19554-B)
to prevent oil leakage between vent
and axle housing. Connect the vent
tube to the vent.
10.
Install the pinion side gears and
thrust washer.
11.
Slide the axle shafts into place
in the axle housing. Exercise care that
splines or any portion of the axle
shafts do not damage the oil seals and
that they engage with the splines of
the differential side gears.
12.
Install the axle shaft C-lock O-
ring and C-lock on the inner end of
the shaft and push the shaft outward
so that the shaft lock seats in the
counterbore of the differential side
gear.
13.
Position the pinion differential
gears and thrust washers 180 degrees
apart to the differential side gears.
Revolve the gear assembly until the
holes in the differential case are al-
igned with the pinion gears.
14.
Position the differential pinion
shaft through the case and pinions, al-
igning the hole in the shaft with the
lock bolt hole. Install the lock bolt
and tighten it to specification.
15.
Clean the gasket mounting sur-
face of the rear axle housing and the
cover. Install a new cover gasket,
cover and the attaching bolts. Torque
the bolts to specification.
16.
Raise the rear axle on a hoist
and remove the safety stands.
17.
Connect the track bar to the
mounting stud. Install the washer and
nut. Torque the nut to specification.
18.
Connect the two rear shock ab-
sorbers to the mounting brackets on
the axle housing and torque the at-
taching nuts to specification.
19.
Make sure that both the front
and rear pivot bolts of the upper and
the two lower arms are loose, then
raise the axle assembly to the con-
trolled height (Fig. 8). Hold the axle
at the controlled height by placing
blocks or pieces of steel pipe between
the axle housing and the bumper rear
screw on the side rail.procarmanuals.com

DISASSEMBLY OF
DIFFERENTIAL CASE
1.
If the 2 differential side bearings
are to be removed from the differen-
tial case, use the tool shown in Fig.

case several revolutions in each direc-
tion while the bearings are loaded to
seat the bearings in their cups. This
step is important.
5. Again loosen the right nut to re-
lease the preload. Check to see that
the left nut contacts the bearing cup.
Using the dial indicator set-up shown
in Fig. 13, Part 4-1, adjust the preload
to 0.008 to 0.012 case spread for new
bearings or 0.005 to 0.008 for the
original bearings, if re-used.
6. Check the runout of the differen-
tial case flange with a dial indicator.
If the runout does not now exceed
specifications, install a new ring gear,
if the runout still exceeds specifica-
tions,
the ring gear is true and the
trouble is due to either a defective
casting or worn bearings.
7.
Remove the differential case
from the carrier and remove the side
bearings from the case.
8. Install new bearings on the case
hubs,
and again install the differential
assembly in the carrier without the
ring gear.
9. Check the case runout again with
the new bearings. If the runout is now
within limits, the old bearings were
excessively worn. Use the new bear-
ings for assembly. If the runout is still
excessive, the case is defective and
should be replaced.
ASSEMBLY OF AXLE
Refer to Part 4-1 of this Shop
Manual for Cleaning and Inspection
procedures before starting assembly
operations.
ASSEMBLY OF
DIFFERENTIAL CASE
1.
Place the ring gear on the differ-
ential case. Install the retaining bolts
and torque them to specification.
2.
If the differential bearings were
removed, press them on as shown in
Fig. 17.
3.
Insert the pinion gear shaft lock
bolt into the case (loosely).
INSTALLATION OF DRIVE
PINION AND
DIFFERENTIAL CASE
1.
Place the shim(s) and pinion rear
bearing cone on the pinion shaft.
Press the bearing and shim(s) firmly
against the pinion shaft shoulder (Fig.
18).
2.
Place a new pinion bearing pre-
load (collapsible) spacer on the pinion
shaft.

3.
Lubricate the pinion rear bearing
with axle lubricant.
4.
Lubricate the pinion front bear-
ing with axle lubricant. Lubricate the
pinion front bearing cone and place it
in the carrier housing.
5.
Install a new oil seal in the car-
rier casting (Fig. 19).
6. Insert the drive pinion shaft (U-
joint) flange into the pinion seal and
hold it firmly against the pinion front
bearing cone. From the rear of the
carrier casting, insert the pinion shaft
into the flange.
7.
Apply a small amount of lubri-
cant to the washer side of the flange
nut and start the nut. Use a new nut.
Hold the flange with the tool shown in
Fig. 12 and tighten the pinion shaft
nut. As the pinion shaft nut is tight-
ened, the pinion shaft is pulled into
the front bearing cone and into the
flange.
As the pinion shaft is pulled into
the front bearing cone, pinion shaft
end play is reduced. While there is
still end play in the pinion shaft, the
flange and cone will be felt to bottom.
This indicates that the bearing cone
and flange have bottomed on the col-
lapsible spacer.
From this point, a much greater
torque must be applied to turn the
pinion shaft nut, since the spacer must
be collapsed. From this point, also,
the nut should be tightened very slow-
ly and the pinion bearing preload play
checked often, so that the pinion bear-
ing preload does not exceed the speci-
fied limits.
If the pinion shaft nut is tightened
to the point that pinion bearing pre-
load exceeds the limits, the pinion
shaft must be removed and a new col-
lapsible spacer installed. Do not de-
crease the preload by loosening the

pinion shaft nut. This will remove the
compression between the pinion front
and rear bearing cones and the col-
lapsible spacer and may permit the
front bearing cone to turn on the pin-
ion shaft.
8. As soon as there is preload on
the bearings, turn the pinion shaft in
both directions several times to seat
the bearing rollers.
9. Adjust the bearing preload to
specification. Measure the preload
with the tool shown in Fig. 20.
10.
Apply a thin coating of lubri-
cant on the bearing bores so that the
differential bearing cups will move
easily.
11.
Place the cups on the bearings
and set the differential case assembly
in the carrier casting.
If the gear set is of the non-hunting
or partial non-hunting type, assemble
the differential case and ring gear as-
sembly in the carrier so that the
marked tooth on the pinion indexes
between the marked teeth on the ring
gear as shown in Fig. 49, Part 4-2.
In almost every case of improper
assembly (gears assembled out of
time),
the noise level and probability
of failure will be higher than they
would be with properly assembled
gears.

sembly in the carrier without regard
to the matching of any particular gear
teeth.
12.
Slide the case assembly along
the bores until a slight amount of
backlash is felt between the gear teeth.
Hold the differential case in place.
13.
Set the adjusting nuts in the
bores so that they just contact the
bearing cups.
14.
Carefully position the bearing
caps on the carrier casting. Match the
marks made when the caps were re-
moved (Fig. 21).
15.
Install the bearing cap bolts
and lockwashers. As the bolts are
tightened, turn the adjusting nut with
the tool shown in Fig. 21.
16.
If the adjusting nuts do not turn
freely as the cap bolts are tightened,
remove the bearing caps and again in-
spect for damaged threads or incor-
rectly positioned caps. Tightening the
bolts to the specified torque is done to
be sure that the cups and adjusting
