specification whenever the rear axle

has been removed.

Before checking the drive shaft pin-

ion angle, alignment height spacer

(Tool T65P-3OOO-B or C) must be in-

stalled at a height of 4.30 inches (Fig.

Checking Procedure

The checking and adjusting proce-

dure must be done with the weight of

the vehicle on the front and rear sus-

Angle Adjustment

1.
Position the magnetized Tool

T68P-4602-A on a U-joint bearing

cap as shown in Fig. 15.

2.
With the tool suspended straight

down and the adjusting screw to the

left, adjust the dial on the tool until

the left-hand edge of the bubble is ex-

actly on the zero line.

3.
Position the vee magnet on the

drive shaft away from welds and bal-

ance weights (Fig. 15).

4.
Position the magnetized tool

(T68P-4602-A) on the vee magnet

with the adjusting screw to the left in

the same relative position as it was on

the bearing cap (Fig. 16).

5.
Read the position of the bubbles

left-hand edge on the scale to deter-

mine the drive shaft pinion angle. The

reading should be 3 1/2 degrees plus 1
degree on Ford, Mercury or Meteor

models, 7 1/4 degrees plus 3/4 degree

on Thunderbird or Continental Mark

III models.

Adjustment

If the pinion angle is not within

specifications, adjust the pinion angle

as follows:

The upper arm-to-axle housing bolt

and two eccentric washers form an ad-

justing cam mechanism (Fig. 17)

which will tilt the axle housing to the

required angle.

1.
Loosen the upper arm pivot bolt

nuts.

2.
If the angle is less than specifica-

tions,
rotate the adjusting cam for-

ward and recheck the angle. If the

angle is more than specification, ro-

tate the adjusting cam rearward and

recheck the angle.

3.
When the axle housing is adjust-

ed in such a way that the drive shaft

angle reading is within specification,

install new pivot bolt nuts and torque

to specification (Fig. 17).

4.
Lower the vehicle and road test

for proper axle operation.

REMOVAL AND INSTALLATION

HOISTING INSTRUCTIONS

Damage to steering linkage compo-

nents and front suspension struts may

occur if care is not exercised when po-

sitioning the hoist adapters of 2 post

hoists prior to lifting the vehicle.

If a 2 post hoist is used to lift the

vehicle, place the adapters under the

lower arms or the No. 1 crossmember.

Do not allow the adapters to contact

the steering linkage. If the adapters

are placed under the crossmember, a

piece of wood (2 x 4 x 16 inches)

should be placed on the hoist channel

between the adapters. This will pre-

vent the adapters from damaging the

front suspension struts.

MAJOR REPAIR OPERATIONS

DISASSEMBLY
OF

DIFFERENTIAL CARRIER

CONVENTIONAL

DIFFERENTIAL

A disassembled view
of the
rear

axle assembly
is
shown
in Fig. 17.

After mounting
the
carrier
in a

holding fixture, disassemble
the car-

rier
as
outlined
in the
following proce-

dures:

1.
Mark
one
differential bearing

cap
and the
mating bearing support

with punch marks
to
help position
the

parts properly during assembly
of the

carrier. Also, mark
one of the
bearing

adjusting nuts
and the
carrier with

AXLE SHAFT-4725
RETAINER RING-1100
scribe marks
for
proper location
dur-

ing assembly.

2.
Remove
the
adjusting
nut
locks,

bearing caps,
and
adjusting nuts. Then

lift
the
differential case assembly
out

of
the
carrier.

(Remove
the
bearing caps
by tap-

ping
the
caps lightly with
a
soft
mal-

let).

3.
Remove
the
differential bearings

with
the
tools shown
in Fig. 18.

4.
Mark
the
differential case, cover,

and ring gear
for
assembly
in the
orig-

inal position.

5.
Remove
the
bolts that attach
the

ring gear
to the
differential case. Press

the gear from
the
case
or tap it off

with
a
soft-faced hammer.

6. With
a
drift, drive
out the
differ-

and separate

7.
Drive
out the
pinion shaft with
a

brass drift
(Fig. 20).

8. Remove
the
gears
and
thrust

washers
(Fig. 48).

1.
Remove
the
differential case

from
the
carrier
and
remove
the
bear-

ings from
the
differential case
in the

same manner
as the
conventional
dif-

ferential case.

2.
Place
the
differential case
in a

hydraulic press,
and
apply about
one

ton pressure across
the
case bearing

hubs while removing
the

3.
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

breakaway torque required
to
start
the

side gear turning
may
exceed
300 ft-

lbs.
Observe only
the
torque required

for continuous even rotation. There

should
be no
abnormal roughness
or

binding.
In
some instances
the
rotat-

ing torque
may
reach
250
ft-lbs, this

condition
is
acceptable,
if
rotation
is

smooth.
If the
results
of the
bench

check
are not
within specified limits,

internal trouble
may be
present
and

should
be
corrected before installing

the assembly
in the
vehicle. Some

possible torque problems
