REAR AXLE SHAFT, WHEEL

BEARING AND OIL SEAL

REPLACEMENT

The rear axle shafts, wheel bear-

ings,
and oil seal can be replaced

without removing the differential as-

sembly from the axle housing.

REMOVAL OF

AXLE SHAFT

Synthetic wheel bearing seals are

used in production only. Removal and

insertion of rear axle shafts must be

performed with caution. The entire

length of the shaft (including spline)

up to the seal journal must pass

through the seal without cutting of the

seal element during axle removal or

installation will result in early seal fai-

lure.
Leather seals only will be used as

service replacement for synthetic

wheel bearing seals.

1.
Remove the wheel cover, wheel

and tire from the brake drum.

2.
Remove the nuts that secure the

brake drum to the axle shaft flange,

then remove the drum from 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. 4). The brake backing

plate must not be dislodged. Install

one nut to hold the plate in place after

the axle shaft is removed.

REMOVAL OF REAR

WHEEL BEARING AND

SEAL

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvents.

Removal of the wheel bearings from

the axle shaft makes them unfit for

further use.

1.
On all models except Ford, Mer-

cury or Meteor, 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. 5). It will then slide off easily.
E 1731-A

FIG. 5—Removing Rear Wheel

Bearing Retainer Ring

On Ford, Mercury and Meteor mo-

dels,
it is necessary to first drill a 1/4

inch hole not more than 5/16 inch

deep in the retainer ring surface bef-

ore using the cold chisel.

2.
Remove the bearing from the

axle shaft with the tool shown in Fig.

6 or Fig. 7.

3.
Whenever a rear axle shaft is re-

placed, the oil seal must be replaced.

Remove the seal with Tool 1175-AB

and a slide hammer (Fig. 8). If new

leather-type wheel bearing service

seals are to be installed, soak new oil

seals in SAE 10 oil for 1/2 hour

before installing.

INSTALLATION OF REAR

WHEEL BEARING AND

SEAL

1.
Inspect the machined surface 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 twist. Care-

fully remove any burrs or rough spots.

Replace worn or damaged parts.

2.
Lightly coat wheel bearing bores

with axle lubricant.

3.
Place the retainer plate on the

axle shaft, and press the new wheel

bearing on the shaft with the tool

shown in Fig. 6 or Fig. 9. Do not at-

tempt to press on both the bearing

and the inner retainer ring at the same

time.

4.
Using the bearing installation

tool (Tool 4621-A or 4234-4), press

the bearing inner retainer ring on the

shaft until the retainer seats firmly

against the bearing. On Ford, Mercu-

ry, or Meteor models, before assem-

bling the retainer onto the axle shaft,

the shaft journal and the inside di-
ameter of the retainer should be wiped

clean with a dry cloth. These parts

must not be degreased or lubricated.

5. Rear wheel oil seals with synthe-

tic sealing elements have been incor-

porated in production only. However,

leather seals only will be used as re-

placements for the synthetic sealing

elements. Install the new oil seal with

the tools shown in Figs. 10 and 12. Be

sure the new seal has been soaked in

SAE 10 oil for 1/2 hour before in-

stalling it. Wipe a small amount of oil

resistant sealer on the outer edge of

the seal before it is installed. Do not

put sealer on the sealing lip.

INSTALLATION OF

AXLE SHAFT

1.
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.

2.
Install the bearing retainer plate

and the nuts that secure it. Torque the

nuts to specifications.

3.
Install the brake drum and the

drum attaching (Tinnerman) nuts.

4.
Install the wheel and tire on the

drum. Install the wheel cover.

DRIVE PINION OIL SEAL

REPLACEMENT

COLLAPSIBLE SPACER

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvent.

The drive pinion oil seal can be re-

placed without removing the differen-

tial carrier assembly from the axle

housing.

1.
Raise the vehicle and install

safety stands. Remove both 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. 11). 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 fluidprocarmanuals.com

Thread Repair-Case

Thread service kits may be pur-

chased from local jobbers or the

Heli-Coil Corporation. To repair a

damaged thread, the following proce-

dures should be carefully followed.

1.
Drill out the damaged threads,

using the same drill size as the thread

01).
For example, use a 5/16-inch

drill for a 5/16-18 thread.

2.
Select the proper special tap and

tap the drilled hole. The tap is marked

for the size of the thread being re-

paired. Thus, the special tap marked

5/16-18 will not cut the same thread

as a standard 5/16-18 tap. It does cut

a thread large enough to accommo-

date the insert, and after the insert is

installed the original thread size

(5/16-18) is restored.

3.
Select the proper coil inserting

tool. These tools are marked with the

thread size being repaired. Place the

insert on the tool and adjust the sleeve

to the length of the insert being used.

Press the insert against the face of

the tapped hole. Turn the tool clock-

wise and wind the insert into the hole

until the insert is 1/2 turn below the

face.

4.
Working through the insert, bend

the insert tang straight up and down

until it breaks off at the notch.

5.
If the inserts are not properly in-

stalled, they can be removed with the

extractor tool. Place the extractor tool

in the insert so that the blade rests

against the top coil 1/4 to 1/2 turn

away from the end of the coil. Tap

the tool sharply with a hammer so

that the blade cuts into the insert.
