COMMON ADJUSTMENTS
AND
REPAIRS

IDENTIFICATION

The AXLE code on the vehicle

Warranty Plate (Fig. 1) identifies the

rear axle type (conventional or

limited-slip differential) and gear

ratio.

A metal tag (Fig. 2) stamped with

the model designation and gear ratio

is secured to one of the rear cover-

to-housing bolts (integral carrier-type)

or to one of the carrier-to-housing

bolts (removable carrier-type).

The spaces on the top line provide

the axle model identification code.

This code, such as WDT-AN4,

WDC-AS4, WEG-C2, etc. indicates a

specific combination of the following

factors: conventional or limited slip

differential; diameter of ring gear;

small or large wheel bearings; and the

gear ratio. Refer to the specifications

group of this manual for the car-line

rear axle ratios, gear and code
identif-

ication.

The second line on the tag is used

for gear ratio, the production date

code and the production plant identifi-

cation code.
It is important to use the model

designation when obtaining correct re-

placement parts.

LIMITED-SUP
OR

TRACTION-LOK DIFFERENTIAL

OPERATION CHECK

A limited-slip or Traction-Loc dif-
ferential can be checked for proper

operation without removing the carrier

from the axle housing.

Jack up one rear wheel and remove

the wheel cover. Install the tool on the

axle shaft flange studs as shown in

Fig. 3.

FIG. 3—Limited-Slip Differential Check

Using
a
torque wrench
of at
least

200 ft-lbs capacity, rotate
the
axle

shaft.
Be
sure that
the
transmission
is

in neutral,
one
rear wheel
is on the

floor,
and the
other rear wheel
is

raised
off the
floor.
The
torque
re-

quired
to
continuously rotate
the
shaft

should
be at
least
75
ft-lbs
or 40
ft-lbs

(Traction-Lok).
The
initial breakaway

torque
may
be
higher than
the
contin-

uous turning torque,
but
this
is nor-

mal.
The
axle shaft should turn with

^ven pressure throughout
the
check

without slipping
or
binding.

If
the
torque reading
is
less than

specified, check
the
differential
for

improper assembly.

A vehicle equipped with
a
limited-

slip differential will always have both

wheels driving.
If,
while
the
vehicle
is

being serviced, only
one
wheel
is

raised
off the
floor
and the
rear axle

is driven
by the
engine,
the
wheel
on

the floor will drive
the
vehicle
off the

stand
or
jack.

GEAR TOOTH CONTACT

PATTERN CHECK

When rolling
a
tooth pattern,
use

the special compound (tube) packed

with each service ring gear
and
pinion

set.

Paint
all
gear teeth
and
roll
a pat-

tern
as
described
in
Section
3.
After

diagnosing
the
tooth pattern
as ex-

plained here, make
the
appropriate

adjustments
as
outlined
in
Section
2.

In making
a
final gear tooth
con-

tact pattern check,
it is
necessary
to

recognize
the
fact that there
are
three

different types
of
gear sets, hunting,

non-hunting
and
partial non-hunting.

Each type
is
determined
by the num-
ber
of
teeth
in the
gears.
The non-

hunting
and
partial non-hunting types

can
be
identified
by the
paint timing

marks
on the
pinion
and
ring gear

teeth. (Part 4-2,
Fig. 51).
See
Part
4-5

for complete identification specifica-

tions.

ACCEPTABLE TOOTH

PATTERNS (ALL AXLES)

Figure
4
shows acceptable tooth

patterns
for all
axles.
Any
combina-

tion
of
drive
and
coast patterns will
be

acceptable.

In general, desirable tooth patterns

should have
the
following character-

istics:

1.
The
drive pattern should
be
fair-

ly well centered
on the
tooth.

2.
The
coast pattern should
be
fair-

ly well centered
on the
tooth.

3.
Some clearance between
the pat-

tern
and the top of the
tooth
is
desir-

able.

4.
There should
be no
hard lines

where
the
pressure
is
high.

The individual gear
set
need
not

conform exactly
to the
ideal pattern

to
be
acceptable.

Any combination
of
drive
and
coast

patterns shown
in Fig. 4 are
accep-

table.

Hunting Gear
Set

In
a
hunting-type gear
set, any one

pinion gear tooth comes into contact

with
all
ring gear teeth.
In
this type,

several revolutions
of
the
ring gear
are

required
to
make
all
possible gear

combinations.
Any combination
of
drive
and
coast

patterns shown
in
Fig.
4
will
be
acceep-

table.

Non-Hunting Gear
Set

In
a
non-hunting type gear
set, any

one pinion gear tooth comes into
con-

tact with only
a few
ring gear teeth.

In this type, only
one
revolution
of
the

ring gear
is
required
to
make
all
poss-

ible tooth contact combinations.
Any

combination
of
drive
and
coast
pat-

terns shown
in Fig. 4
will
be
accept-

able.

Partial Non-Hunting

Gear
Set

In
a
partial non-hunting type gear

set,
any one
pinion tooth comes into

contact with only part
of
the
ring gear

teeth,
but
more than
one
revolution
of

the ring gear
is
required
to
make
all

possible gear tooth combinations.
Any

combination
of
drive
and
coast
pat-

terns shown
in Fig. 4
will
be
accept-

able.

SHIM
AND
BACKLASH

CHANGES

Since each gear
set
rolls
a
charac-

teristic pattern,
the
patterns shown
in

Fig.
4 are
considered acceptable
and

should
be
used
as a
guide.
The
drive

pattern
is
rolled
on the
convex side
of

the tooth,
and the
coast pattern
is

rolled
on the
concave side.

The movement
of
tooth contact
pat-

terns with changes
in
shimming
can
be

summarized
as
follows:

Removable Carrier Type Axle

1.
Thicker shim with
the
backlash

set
to
specifications moves
the
pinion

further from
the
ring gear:

2.
Thinner shim with
the
backlash

set
to
specifications moves
the
pinion

closer
to the
ring gear:

If
the
patterns
are not
correct,

make
the
changes
as
indicated.
The

pinion need
not be
disassembled
to

change
a
shim.
All
that
is
required
is

to remove
the
pinion, bearing,
and re-

tainer assembly
and
install
a
different

shim. When reinstalling
the
pinion

and retainer assembly
of a
non-
hunt-

ing
or
partial non-hunting gear
set, be

sure that
the
marked tooth
on the pi-

nion indexes between
the
marked teeth

on
the
ring gear
(Fig.
51,
Part
4-2).

If the tooth pattern indicates a change

in shim thickness, follow the proce-

dure under Pinion Location.

REMOVABLE CARRIER

TYPE AXLE

The shim location for the removable

carrier type axle is between the pinion

retainer and the carrier (Fig. 13).

When adjusting this type carrier re-

ducing shim thickness will move the

pinion toward the ring gear; increas-

ing shim thickness will move the pi-

nion away from the ring gear (Fig.

13).

8. If the runout is still excessive, re-

place the companion flange and check

the runout. If necessary, rotate the

new flange on the pinion shaft until an

acceptable runout is obtained.

If excessive runout is still evident

after replacement of the companion

flange, it will be necessary to replace

the ring and pinion gear, and repeat

the above checks until runout is within

specifications.

set require the use of shims to locate

the pinion for correct contact with the

ring gear.

When adjusting either type axle,

shim thickness should be increased or

reduced only as indicated by the tooth

pattern check described in the fore-

going Section 1.

If the tooth pattern check indicates

a change in backlash only, follow the

The shim location for the integral

carrier type axle, is between the pi-

nion gear and the pinion rear bearing

cone (Fig. 12). When adjusting this

type axle, increasing shim thickness

moves the pinion toward the ring

gear; reducing shim thickness moves

the pinion away from the ring gear

(Fig. 12).

ADJUSTMENTS (ALL AXLES)

On a Light-Duty (WER) Axle, it is

necessary to remove the rear axle

shafts prior to performing the adjust-

ment procedures. Refer to Rear Axle

Shaft Wheel Bearing and Oil Seal Re-

placement—Light-Duty (WER), Axle,

Part 4-4, Section 2.

To secure a more uniform control

of differential side bearing preload in

service repairs, a dial indicator set-up

such as shown in Fig. 12 is used.

In both types of axle (Fig. 11 and

12),
the ring gear is moved away from

or toward the pinion as described in

the following procedure.

1.
Remove the adjusting nut locks,

loosen the differential bearing cap

bolts,
then torque the bolts to 15 ft-lbs

on integral carrier type axle; 20 ft-lbs

on removable carrier type axles before

making adjustments.

2.
The left adjusting nut is on the

ring gear side of the carrier. The right

nut is on the pinion side. Loosen the

right nut until it is away from the cup.

Tighten the left nut until the ring gear

is just forced into the pinion with

0.000 backlash then rotate the pinion

several revolutions to be sure no bind-

ing is evident. (Recheck the right nutprocarmanuals.com

1 DESCRIPTION

CONVENTIONAL AXLE

The rear axle is of the banjo-

housing, hypoid gear type using an 8
3/4, 9 or 9 3/8 inch ring gear, in

which the centerline of the pinion is

mounted below the centerline of the

ring gear (Fig. 1).
The pinion gear and the pinion

bearings are assembled in a pinion re-

tainer, which is bolted to the carrier.

The pinion is straddle mounted; that

is,
it is supported by bearings both in

front of and to the rear of the pinion

gear. Two opposed tapered roller

bearings support the pinion shaft in

front of the pinion gear with a col-

lapsible spacer for 8-3/4 inch or 9

inch ring gear, and a solid spacer used

with the 9 3/8 inch ring gear. A

straight roller (pilot) bearing supports

the pinion shaft at the rear of the pi-

nion gear. Pinion and ring gear tooth

contact is adjusted by adding or re-

moving shims from between the pinion

retainer and the carrier housing.

The differential assembly is mount-

ed on two opposed tapered roller

bearings, which are retained in the

carrier by removable caps. The entire

carrier assembly is bolted to the axle

housing.

Ball bearing assemblies (rear wheel

bearings) are pressed onto the outer

ends of the axle shafts and set in the

outer ends of the axle housing. These

bearings support the semi-floating

axle shafts at the outer ends. The

inner ends of the shafts spline to the

differential side gears. Bearing retain-

er plates hold the shafts in the hous-

ing. The left and right axle shafts are

not interchangeable, the left shaft

being shorter than the right.

FIG. 2—Limited-Slip Differential

LIMITED-SUP DIFFERENTIAL

The axle assembly, except for the

differential case and its internal com-

ponents, is identical to the convention-

al axle.

A constant-friction locking differen-

tial,
which employs clutch plates to

control differential action, is available

as optional equipment (Fig. 2).

Four steel clutch plates are locked

into the differential cover. Three

bronze, bonded clutch plates are

splined to a clutch hub which, in turn,
is splined to the left axle shaft. A

Belleville spring washer maintains a

constant pressure between the steel

and bonded clutch plates so that the

clutch is always engaged.

TRACTION-LOK

DIFFERENTIAL

The Traction-Lok (torque sensitive)

locking differential (Fig. 3) employs a

multiple disc clutch to control differ-

ential action. Shim(s), which control

side gear mounting distance, four

steel, four friction and one composite

plate (steel on one side and friction

material on the other) stacked on a

clutch hub, and four ear guides are

housed in the differential cover. Lo-

cated in the differential case between

the side gears is a one-piece pre-load

plate and block (four-pinion) and four

calibrated pre-load springs, which

apply an initial force to the clutch

pack. Additional clutch capacity is

derived from the side gear thrust

loads.
The four friction plates are

splined to the clutch hub which in turn

is splined to the left axle shaft, and

the eared steel plates are dogged to

the case; thus, the clutch is always en-

gaged.

IN-VEHICLE ADJUSTMENTS AND REPAIRS

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.

FIG. 4—Removing Axle Shaft

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
