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).

Flange

4.
The
rear axle companion flange

runout
is
checked with
a
modified uni-

versal joint (checking tool)
a
dial indi-

cator with
1.000
inch minimum travel,
and
a
cup-shaped dial indicator adapt-

er tool
(Fig. 6). To
fabricate
the

checking tool, modify
a
universal joint

assembly
by
removing
two
bearing

cups that are opposite each other, and

cuttting
or
grinding
off
one
of
the uni-

versal joint bearing flanges (Fig. 6).

5.
Install
the
cup-shaped adapter
on

the dial indicator stem. Install
the
dial

indicator
on the
pinion retainer
or pi-

nion nose bumper bracket. Position

the indicator
to
allow
an
indication
at

the ends
of the
universal joint bearing

cups
and the
remaining exposed jour-

nal
of the
cross-shaft.

6. Turn
the
companion flange
so

that
the
dial indicator cup-type adapt-

er rests
on the
machined surface
of

the bearing
cup (Fig. 6).
Rotate
the

companion flange side-to-side slightly

to obtain
a
reading indicating that
the

bearing
cup
surface
is
perpendicular
to

the indicator cup-type adapter. This

will
be the
point
at
which
the
dial
in-

dicator
cup is
closest
to the
center
of

companion flange rotation.
It is
also

the point
at
which
the
dial indicator

hand will reverse direction
as
the com-

panion flange
is
turning.
Set the
dial

indicator
to
zero.

Carefully retract
the
dial indica-

tor stem
and
rotate
the
companion

flange 180 degrees
to
position
the ma-

chined surface
of the
opposite univer-

sal bearing under
the
dial indicator

adapter tool. Again, slightly rotate
the

flange side-to-side
to
position
the

bearing perpendicular
to the
dial indi-

cator adapter. Again, this
is the
point

at which
the
indicator hand will
rev-

erse direction
as the
flange
is
rotated.

Record
the
flange bearing
cup
runout

reading obtained from
the
indicator

(Fig.
7).

Rotate
the
companion flange
90

degrees
and
position
the
dial indicator

adapter
on the
machined
end of the

exposed journal
(Fig. 8). Be
sure
the

end surface
of the
exposed journal
is

perpendicular
to the
indicator
cup-

type adapter. This requires that
the

cross-shaft
be
moved fore
and aft on

the flange bearing cups. Note
the

point
at
which
the
indicator hand rev-

erses direction. Rotate
the
flange
as-

sembly side-to-side until
the
cross-

shaft
is
perpendicular
to the
pinion

shaft axis,
and the
indicator hand
re-

verses direction. Zero the dial indicator

and check the zero point again by
