Center
the
Belleville spring
on

the clutch pack (spring concave-side

facing downward
on the
pack)
to pre-

vent trapping
the
spring between
the

left
and
right handcase
in an
eccentric

position
(Fig. 54).
Improper location

of
the
Belleville spring will cause
ex-

tremely high torque
and
differential

chatter.
Be
sure
the
slots
in the
rabbit

ears
of the
steel plates
are in
proper

alignment.

4.
Carefully
set the
differential case

cover over
the
right hand case
(Fig.

55).
At
this point,
no
force
or
pressure

should
be
applied
to the
cover.
The

cover contains
two 3/16
inch holes
by

which
the
clutch plates
can be
proper-

ly aligned. Insert
the
shank ends
of
two
1/8
inch drill bits into
the
holes,

and work
the
drill bits back-and forth

until
the
plates
are
centered
(Fig. 55).

When
the
clutch plates
are
centered,

the weight
of the
cover will cause
it to

fall into position. Remove
the
drill

bits.

5.
Install
the
ring gear
to
differen-

tial case bolts,
and
tighten them even-

ly
and
alternately across
the
diameter

of
the
ring gear. Tighten
the
bolts
to

specification.

6. Prior
to
installation
of the

limited-slip differential into
the ve-

hicle,
a
differential torque check must

be made. Check
the
torque required
to

rotate
one
side gear while
the
other

side gear
is
held
(Fig. 56). The

Install the pinion thrust washers

and place the pinion gears on the side

gear; aligning the holes in the washers

and gears with the holes in the case.

4.
Install the center block so that

the shaft holes are aligned with the

holes in the pinion gears and case.

The center block has two machined

sides and two rough sides.

5.
With a brass drift, drive in the

long pinion shaft from the outside of

the case aligning the lock pin holes in

the shaft with the holes in the case.

The center block should be positioned

so the long shaft is driven through the

rough side and short shafts driven

through the machined side (Fig. 57).

6. With a suitable drift, install the

shaft lock pins. Make sure the pinion

and side gears move freely.

7.
Place the four pre-load springs in

the holes provided in the center block.

8. Position a pre-load plate over the

four springs, making sure the springs

are properly seated. The pre-load

plate straddles the center block over

its narrower or machined width.

9. Mount the differential cover in a

soft jawed vise or holding fixture.

10.
Insert shim(s) of 0.050 total

thickness in the cover cavity.

11.
Install the composite plate (fric-

tion material on one side and steel on

the opposite) on the back side of the

clutch hub with the friction material

against the hub; next, install a friction

plate, then steel, friction, stee, fric-

tion, steel, friction, and lastily a steel

plate (Figures 3 and 58). When new

clutch plates are used, soak the plates

in Ford Hypoid Lubricant (Ford Part

No.
C6AZ-19580-C), or equivalent lu-

bricant, for approximately 30 minutes

before installation.

12.
Place the clutch hub with the

clutch plates into the clutch ear cavi-

ties in the differential cover. Make

sure that the splines on the last fric-

ion plate are engaged on the hub.

13.
Obtain locally a 5/8 inch x

2 1/2 inch or 9/16 inch x 2 1/2

inch bolt, nut and two I 1/2 inch

outside diameter flat washers approx.

1/8 inch in thickness. These parts are

required to compress the clutch pack

in order to obtain the proper shim

selection.

Install a flat washer on the bolt,

and place the bolt through the clutch

hub.
Hold the bolt in position and

turn the cover over. Place a flat wash-

er on the bolt and then install the nut.

Be sure the washers are centered, and

torque the nut 10 to 15 ft-lbs (Fig.

observed between the shim tool and

the cover-to-case mating surface.

Using a feeler gauge, determine the

exact amount of clearance. Refer to

the shim pack thickness chart specifi-

cations which will indicate the correct

amount of shim(s) to subtract from

the 0.050 shim originally installed. In

order to correctly select the proper

shim(s), the shim template tool and

the chart must be used.

15.
After the proper shim selection

is determined, remove the bolt, nut

and flat washers. If it is necessary to

revise the shim thickness, remove the

clutch hub and clutch plates.

16.
Install the selected shim(s) in

the cover cavity, reinstall the compo-

nents as outlined in Steps 11 and 12.

17.
Install the four steel clutch ear

guides and side gear.

18.
Place both assemblies in a

press,
and press the two halves togeth-

er; then, insert the two Allen or Phil-

lips head screws, and tighten evenly

until tight. If a press is not available,

any two stock bolts and nuts may be

used opposite each other in the ring

gear retaining holes to compress both

halves.

19.
Install the ring gear and ring

gear bolts and washers. Tighten evenly

and alternately across the diameter of

the ring gear. Torque the bolts to

65-80 ft-lbs.

20.
Prior to installation of the tor-

que sensitive locking differential into a

vehicle, a bench torque check must be

made. Check the torque required to

rotate one side gear while the other is

held stationary (Fig. 56). The initial

break-away torque may exceed 250

ft-lbs.
The rotating torque required to

keep the side gear turning with new

clutch plates is 100 to 250 ft-lbs. With

re-used clutch plates, the minimum

torque required is 40 ft-lbs. (The tor-

que may fluctuate 10-40 ft-lbs.).

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.

flange.

13.
Install a new integral nut and

washer on the pinion shaft. (Apply a

small amount of lubricant on the

washer side of the nut.)

14.
Hold the flange with the tool

shown in Fig. 9 while tightening the

nut.

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).

19.
Check the lubricant level. Make

As the
pinion shaft
nut is
tight-

ened,
the
pinion shaft
is
pulled into

the front bearing cone
and
into
the

As
the
pinion shaft
is

FIG. 24—Differential Bearing

Installation
If
the
pinion shaft
nut is
tightened

to
the
point that pinion bearing
pre-

load exceeds
the
limits,
the
pinion

shaft must
be
removed
and a
new
col-

lapsible spacer installed.
Do not de-

crease
the
preload
by
loosening
the

pinion shaft
nut.
This will remove
the

compression between
the
pinion front

and rear bearing cones
and the col-

lapsible spacer
and may
permit
the

front bearing cone
to
turn
on the pin-

ion shaft.

&
As
soon
as
there
is
preload
on

the bearings, turn
the
pinion shaft
in

both directions several times
to set the

bearing rollers.

9. Adjust
the
bearing preload
to

specification. Measure
the
preload

with
the
tool shown
in Fig. 6.

10.
Apply
a
thin coating
of
lubri-

cant
on the
bearing bores
so
that
the

differential bearing cups will move

easily.

11.
Place
the
cups
on the
bearings

and
set the
differential case assembly

in
the
carrier casting (Fig.
17).

If
the
gear
set is of the
non-hunting

or partial non-hunting type, assemble

the differential case
and
ring gear
as-

sembly
in the
carrier
so
that
the

marked tooth
on the
pinion indexes

between
the
marked teeth
on the
ring

gear
as
shown
in Fig. 25.

In almost every case
of
improper

assembly (gears assembled
out of

time),
the
noise level
and
probability

of failure will
be
higher than they

would
be
with properly assembled

gears.

When installing
the
hunting type

gear
set (no
timing marks), assemble

the differential case
and
ring gear
as-

sembly
in the
carrier without regard

to
the
matching
of any
particular gear

teeth.

12.
Slide
the
case assembly along

the bores until
a
slight amount
of

backlash
is
felt between
the
gear teeth.

Hold
the
differential case
in
place.

13.
Set the
adjusting nuts

bores so that they just contact the

bearing cups.

14.
Carefully position the bearing

caps on the carrier casting. Match the

marks made when the caps were re-

moved.

15.
Install the bearing cap bolts

and lockwashers. As the bolts are

tightened, turn the adjusting nut with

the tool shown in Fig. 26.

16.
If the adjusting nuts do not turn
freely as the cap bolts are tightened,

remove the bearing caps and again in-

spect for damaged threads or incor-

rectly positioned caps. Tightening the

bolts to the specified torcfue is done to

be sure that the cups and adjusting

nuts are seated. Loosen the cap bolts,

and torque them to only 5 ft-lbs be-

fore making adjustments. Refer to

Part 4-1 for backlash and bearing pre-

load adjustment procedures.
LIMITED-SLIP DIFFERENTIAL

For integral carrier limited-slip dif-

ferentials see the repair procedures for

removable carrier limited-slip differen-

tials,
Part 4-2. These procedures are

good for the differential case only.

When the limited slip differential case

has been repaired replace the case

using the procedure for the conven-

tional intergral carrier differendal case
