1.
Remove the wheel cover, wheel

and tire from the brake drum.

2.
Remove the Tinnerman nuts that

secure the brake drum to the axle

housing flange, and then remove the

drum from the flange.

3.
Working through the hole pro-

vided in each axle shaft flange, re-

move the nuts that secure the wheel

bearing retainer plate. Then pull the

axle shaft assembly out of the axle

housing (Fig. 2). The brake backing

plate must, not be dislodged. Install

one nut to hold the plate in place after

the axle shaft is removed.

4.
If the rear wheel bearing is to be

replaced, loosen the inner retainer

ring by nicking it deeply with a cold

chisel in several places (Fig. 3). It will

then slide off easily.

5.
Remove the bearing from the

axle shaft with the tool shown in Fig.

4 or 5. If the push-puller operation

shown in Fig. 5 is used, be sure that

the puller arms contact the flat sur-

face of the axle shaft flange rather

than the bolt heads. Also with this

method, be careful not to damage or

burr the oil seal journal as the bearing

breaks loose.

6. Whenever a rear axle shaft is re-

placed the oil seal must be replaced.

Remove the seal with the tools shown

in Fig. 8. Soak new oil seals in SAE

10 oil for 1/2 hour before installing.

7.
Inspect the machined surfaces of

the axle shaft and the axle housing for

rough spots or other irregularities

which would affect the sealing action

of the oil seal. Check the axle shaft

splines for burrs, wear or damage.

Carefully remove any burrs or rough

spots.
Replace worn or damaged

parts.

8. Lightly coat wheel bearing bores

with axle lubricant.

9. Place the retainer plate on the

axle shaft, and press the new wheel

bearing on the shaft with the tool

shown in Fig. 4 or 5. The bearing

should seat firmly against the shaft

shoulder. Do not attempt to press on

both the bearing and the inner retain-

er ring at the same time.

10.
Using the bearing installation

tool, press the bearing inner retainer

ring on the shaft until the retainer

seats firmly against the bearing.

11.
Wipe all lubricant from the in-

side of the axle housing in the area of

the oil seal before installing the new

seal.

12.
Wipe a small amount of oil res-

istant sealer on the outer edge of the

seal before it is installed. Do not put

sealer on the sealing lip.

13.
Rear wheel oil seals with syn-
thetic sealing elements have been in-

corporated in production. However,

only leather seals will be used as re-

placements for the synthetic sealing

element seals. Install the new oil seal

with the tools shown in Fig. 8. Instal-

lation without use of the proper tool

will distort the seal and cause leakage.

Be sure the new seal has been soaked

in SAE 10 oil for 1/2 hour.

14.
Carefully slide the axle shaft

into the housing so that the rough

forging of the shaft will not damage

the oil seal. Start the axle splines into

the side gear, and push the shaft in

until the bearing bottoms in the housing.

15.
Install the bearing retainer plate

on the mounting bolts at the axle

housing, and install the attaching nuts.

Torque the nuts to specifications.

16.
Install the brake drum and the

drum retaining nuts.

17.
Install the wheel and tire on the

drum, and install the wheel cover.

REMOVAL AND REPLACEMENT

OF DRIVE PINION OIL SEAL

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvent.

Replacement of the pinion oil seal

involves removal and installation of

only the pinion shaft nut and the uni-

versal joint flange. However, this op-

eration disturbs the pinion bearing
preload, and this preload must be

carefully reset when assembling.

1.
Raise the vehicle and install safe-

ty stands. Remove the rear wheels and

brake drums.

2.
Make scribe marks on the drive

shaft end yoke and the axle U-joint

flange to insure proper position of the

drive shaft at assembly (Fig. 14). Dis-

connect the drive shaft from the axle

U-joint flange. Be careful to avoid

dropping the loose universal joint

bearing cups. Hold the cups on the

spider with tape. Mark the cups so

that they will be in their original posi-

tion in relation to the flange when

they are assembled. Remove the drive

shaft from the transmission extension

housing. Install an oil seal replacer

tool in the transmission extension

housing to prevent transmission leak-

age.
Refer to the transmission group

for the appropriate tool.

3.
Install an in-lb torque wrench on

the pinion nut Fig. 6. Record the tor-

que required to maintain rotation of

the pinion shaft through several revo-

lutions. \

4.
While holding the flange with the

tool shown in Fig. 9, remove the inte-

gral pinion nut and washer.

5.
Clean the pinion bearing retainer

around the oil seal. Place a drain pan

under the seal, or raise the front of

the vehicle higher than the rear.

15.
Tighten the pinion shaft nut,

rotating the pinion occasionally to in-

sure proper bearing seating, and take

frequent preload readings (Fig. 6)

until the preload is at the original rec-

orded reading established in step 3.

16.
After original preload has been

reached, tighten the pinion nut slowly,

until an additional preload of 6 to 12

in-lbs has been added.

The preload should not exceed the

amount indicated above, or bearing

failure may result. Under no circum-

stances should the pinion nut be

backed-off to lessen preload. If this is

done, a new pinion bearing spacer

must be installed. In addition, the U-

joint flange must never be hammered

on, or power tools used.

17.
Remove the oil seal replacer

tool from the transmission extension

housing. Install the front end of the
drive shaft on the transmission output

shaft.

18.
Connect the rear end of the

drive shaft to the axle U-joint flange,

aligning the punch marks made on the

drive shaft end yoke and the axle U-

joint flange (Fig. 14).

REMOVAL AND INSTALLATION

AXLE HOUSING

Refer to Fig. 7.

REMOVAL

1.
Raise the vehicle on a hoist.

2.
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.
Disconnect the lower end of the

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
