MAJOR REPAIR OPERATIONS

DISASSEMBLY

Disassembly of the pump and its

subassemblies must be made on a

clean work bench. In repairing any

hydraulically operated unit, cleanliness

is of utmost importance. Clean the ex-

terior of the unit with a suitable sol-

vent and drain as much of the fluid as

possible.

If only the reservoir is to be re-

moved, plug the inlet and outlet open-

ings with masking tape or plugs. Do

not immerse the shaft oil seal in sol-

vent. If only the rotor shaft seal is to

be replace, see Rotor Shaft Seal Re-

placement outlined in this section.

1.

lower arm-to-axle housing pivot bolts

and nuts to specifications.

14.
Remove the oil seal replacer

tool from the transmission extension

housing. Position the drive shaft so

that the front U-joint slip yoke splines

to the transmission output shaft.

15.
Connect the drive shaft to the

U-joint flange, aligning the scribe

marks made on the drive shaft end

yoke and the axle U-joint flange dur-

ing the removal procedure. Install the

U-bolts and nuts and torque to speci-

fications.

16.
Carefully slide the two axle

shaft assemblies in the axle housing.

The shorter shaft goes into the left

side of the housing. Use care in slid-

ing the axle shafts into the housing so

that the rough forging of the shaft will

not damage the oil seal. Start the axle

splines into the differential side gear,

and push the shaft in until the rear

wheel bearing bottoms in the housing.

17.
Install the rear wheel bearing

retainers on the attaching bolts on the

axle housing flanges. Install the nuts

on the bolts and torque to specifica-

tions.

If the rear brake shoes were

backed off, adjust the brakes as out-

lined in Part 2-1, and install rubber

plugs in the adjuster slots.

19.
Install the two rear brake

drums and the drum attaching (Tin-

nerman) nuts.

20.
Install the rear wheels and tires.

21.
Fill the rear axle to the bottom

of the filler plug hole located in either

the carrier casting or housing cover

with specified lubricant. Be sure that

the axle is in operating position.

22.
Road test the vehicle to be sure

that pinion and driveshaft angles are
correct. Any shudder during heavy ac-

celeration, or deceleration may require

a pinion and driveshaft angle re-

adjustment as detailed in Driveshaft

and Pinion Angle Adjustment, Group

3,
Part 3-2.

and both axle shafts as outlined in

Section 2.

6. Remove vent hose front vent

tube (Corbin clamp) and remove vent

tube from brake tube junction and

axle housing.

7.
Remove the hydraulic brake T-

fitting from the axle housing. Do not

open the hydraulic brake system lines.

Remove the hydraulic brake line from

its retaining clip on the axle housing.

8. Remove both axle shaft oil seals

with the tool shown in Fig. 8.

9. Remove both brake backing

plates from the axle housing and sus-

pend them above the housing with

mechanic's wire. The hydraulic brake

lines and the parking brake cables are

still attached to the brake backing

plates.

10.
Support the rear axle housing

on a jack, and then remove the spring

clip nuts. Remove the spring clip

plates (Fig. 16).

11.
Lower the axle housing and re-

move it from under the vehicle.

placed, transfer all the differential and

pinion parts to the new housing. See

Section 4, Major Repair Operation*.

INSTALLATION

1.
Raise the axle housing into posi-

tion so that the spring clip plates can

be installed. On a Montego or Fair-

lane,
position the spring upper insula-

tors and retainers between the axle

housing and springs and install theprocarmanuals.com

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.
