the rear axle cover to housing attach-

ing bolts. Drain the housing.

4.
Remove the attaching (Tinner-

man) nuts that secure the brake drums

to the axle shaft flanges, and then re-

move the drums (Fig. 7).

5.
Remove the axle housing cover

bolts,
cover and gasket. Discard the

gasket. Remove the drain pan.

6. Disconnect the drive shaft at the

drive pinion companion flange. Re-

move the drive shaft from the trans-

mission extension housing. Install an

oil seal replacer tool in the transmis-

sion housing to prevent leakage. Refer

to the transmission group for the ap-

propriate tool.

7.
Disconnect the lower end of the

shock absorbers at the mounting

brackets.

8. Disconnect the track bar from

the axle housing stud. If the axle

housing is to be replaced, transfer the

stud to the new housing.

9. Position safety stands under the

rear frame members. Lower the vehi-

cle with the hoist and allow the axle

to lower far enough to relieve rear

spring tension.

10.
Remove the pinion shaft lock

bolt and pinion shaft (Fig. 2), differ-

ential pinion gears and thrust washers.

11.
Push the axle shaft(s) inward

toward the center of the axle housing.

Remove the C-locks from the inner

ends of the axles (Fig. 3). Remove the

axle shafts from the housing. Extreme

care must be used to avoid contacting

the axle shaft seal lip with any portion

of the axle shaft other than the seal

journal.

12.
Disconnect the vent hose from

the rear vent tube and remove all

brake lines from the axle housing re-

taining clips.

13.
Remove the brake backing

plate attaching nuts and the plates

from the axle housing. Suspend the

plates above the axle housing with

mechanics wire. The hydraulic brake

lines and the parking brake cables will

remain attached to the brake backing

plates.
14.
Support the rear axle housine

on a jack.

15.
Remove the right and left rear

springs and insulators.

16.
Remove the nuts, washers and

pivot bolts that connect the suspension

lower arms to the axle housing. Dis-

connect both arms from the axle

housing.

17.
Disconnect the upper suspen-

sion arm from the axle housing by re-

moving the pivot bolt, nut, lock wash-

er and two eccentric washers.

18.
Lower the rear axle to the floor

with the jack and remove the axle

from under the vehicle.

19.

20.
If the axle housing is being re-

placed, transfer all the differential and

pinion parts to the new housing. Refer

to Section 4, Major Repair Operation

for the procedure.

INSTALLATION

1.
Lightly coat the wheel bearing

rollers with axle lubricant. Install

wheel bearings in the axle housing

with the tool shown in Fig. 5. The

bearings should seat firmly against the

shoulder.

2.
Wipe all lubricant from the oil

seal bore before installing the seal. If

axle housing is being replaced, new

seals must be installed.

3.
Inspect the original seal for

nicks,
scuffs or abnormal wear, and

replace if necessary. New seals are

pre-packed with lubricant and do not

require an oil soak.

4.
Install the seal with the tool

shown in Fig. 6. Installation without

the use of the proper tool will distort

the seal and cause leakage.

5. Raise the rear axle into position

under the vehicle with a hoist or floor

jack. Connect the suspension lower

arms to their mounting brackets on

the axle housing with pivot bolts and

nuts.
Do not tighten the mounting

bolts at this point.

6. Position the suspension upper

arm in its mounting bracket on the

axle housing and install the adjusting

bolt, eccentric washers, lock washer

and nut. Do not tighten the mounting

bolt at this point.

7.
Place the rear coil springs and

insulators into position in the pockets

provided.
8. Place the brake backing plates

on the axle housing flanges, install 4

attaching bolts and nuts and torque

them to specifications.

9. Position the brake lines to the

axle housing and secure them with the

retaining clips. If the axle housing is

new, install a new vent. When install-

ing the new axle vent apply a small

amount of Locktite (C5AZ-19554-B)

to prevent oil leakage between vent

and axle housing. Connect the vent

tube to the vent.

10.
Install the pinion side gears and

thrust washer.

11.
Slide the axle shafts into place

in the axle housing. Exercise care that

splines or any portion of the axle

shafts do not damage the oil seals and

that they engage with the splines of

the differential side gears.

12.
Install the axle shaft C-lock O-

ring and C-lock on the inner end of

the shaft and push the shaft outward

so that the shaft lock seats in the

counterbore of the differential side

gear.

13.
Position the pinion differential

gears and thrust washers 180 degrees

apart to the differential side gears.

Revolve the gear assembly until the

holes in the differential case are al-

igned with the pinion gears.

14.
Position the differential pinion

shaft through the case and pinions, al-

igning the hole in the shaft with the

lock bolt hole. Install the lock bolt

and tighten it to specification.

15.
Clean the gasket mounting sur-

face of the rear axle housing and the

cover. Install a new cover gasket,

cover and the attaching bolts. Torque

the bolts to specification.

16.
Raise the rear axle on a hoist

and remove the safety stands.

17.
Connect the track bar to the

mounting stud. Install the washer and

nut. Torque the nut to specification.

18.
Connect the two rear shock ab-

sorbers to the mounting brackets on

the axle housing and torque the at-

taching nuts to specification.

19.
Make sure that both the front

and rear pivot bolts of the upper and

the two lower arms are loose, then

raise the axle assembly to the con-

trolled height (Fig. 8). Hold the axle

at the controlled height by placing

blocks or pieces of steel pipe between

the axle housing and the bumper rear

screw on the side rail.procarmanuals.com

DRIVE SHAFT TESTS

DRIVE LINE BALANCE CHECK

If detailed parts
of the
drive shaft

are replaced
and
shaft vibration
is en-

countered after installation, disconnect

the shaft
at the
slip yoke. Rotate
the

slip yoke
180
degrees; then, reconnect

the shaft
to the
slip yoke.
If the
vibra-

tion persists, disconnect
the
shaft
at

the rear axle companion flange.
Ro-

tate
the
companion flange
180
degrees

and reconnect
the
shaft
to the
flange.
DRIVE LINE ANGLE CHECK

Vibration
or
"shudder" which
is no-

ticeable either
on
fast acceleration
or

when coasting, using
the
engine
for a

brake,
may be
caused
by the
rear axle

housing being loose
on the
rear

springs
or by
improper pinion angle.

Refer
to
Group
3,
Part
2 for
pinion

angle checking procedures.
If the
rear

axle U-bolts (Fairlane, Montego,

Mustang, Cougar, Falcon models
only)
are
loose, torque
the
nuts
to

specification.

DRIVE SHAFT RUNOUT CHECK

Using
a
dial indicator, check
the

runout
at
each
end and in the
middle

of
the
driveshaft.
The
rear check

should
be
made
on the
small tube
sec-

tion
of the
shaft between
the
balance

weights
and the
yoke welds. Drive-

shaft runout should
not
exceed 0.035

inch
at any one
point.

DESCRIPTION

The drive shaft
is the
means
of

transferring power from
the
engine,

through
the
transmission,
to the dif-
ferential
in the
rear axle,
and
then
to

the rear wheels.
The
drive shaft incor-

porates
two
universal joints
and a
slip
yoke
(Fig. 1) or two
double cardan

universal joints,
one at
each
end of the

shaft (Figs.
2 and 3).

the tube assembly. The splines in the

yoke and on the transmission output

shaft permit the drive shaft to move

forward and rearward as the axle

moves up and down.

All drive shafts are balanced. If the

vehicle is to be undercoated, cover the

drive shaft and universal joints to pre-

vent application of the undercoating

REMOVAL AND INSTALLATION

REMOVAL

1.
To maintain drive line balance,

mark the relationship of the rear drive

shaft yoke and the drive pinion flange

of the axle (if the yellow alignment

marks are not visible) with the shaft

so that they may be installed in their

original positions.

2.
Disconnect the rear U-joint or

rear double cardan joint from the

companion flange. Wrap tape around

the loose bearing caps to prevent

them from falling off the spider. Pull

the drive shaft toward the rear of the

vehicle until the slip yoke clears the

transmission extension housing and

the seal. On Lincoln Continental

models, remove the three roller bear-

ing assemblies off the spline teeth in-

side the slip yoke (Fig. 3). Install the

appropriate tool in the extension

housing to prevent lubricant leakage.

If either the rubber seal on the

output shaft or the seal in the end of

the transmission extension housing is
damaged in any manner, replace the

seal or seals as required. Also, if the

lugs on the axle pinion flange are

shaved or distorted so that the bear-

ings slide, replace the flange.

2.
On Lincoln Continental models,

install the bearing assemblies over the

spline teeth in the slip yoke. Lubricate

the yoke spline with B8A-19589-A lu-

bricant. This spline is sealed so that

the transmission fluid does not

"wash" away the spline lubricant

(Figs.
4 and 5). Remove the tool from
the extension housing. Install the yoke

on the transmission output shaft. Do

not allow the yoke assembly to bot-

tom on the output shaft with excessive

force.

Install the drive shaft so that the

index marks or the yellow mark (if

visible) on the yoke (light side) is in

line with the yellow mark on the com-

panion flange. This prevents vibration

which occurs when the balance of the

shaft and balance of the axle pinion

flange become additive instead of neu-

ter yoke.

10.
Remove the bearings from the

driveshaft yoke as outlined above and

remove the spider from the yoke.

11.
Insert a screwdriver into the

centering ball socket located in the

companion flange and pry out the

rubber seal. Remove the retainer, three
piece ball seat, washer and spring

from the ball socket.

12.
Inspect the centering ball socket

assembly for worn or damaged parts.

If any damage is evident replace the

entire assembly.

13.
Repeat Steps 1 through 12 to

disassemble the transmission end of

the driveshaft.

FLYWHEEL HOUSING ALIGNMENT

Alignment of the flywheel housing

bore and rear face with the engine

should be checked as a possible cause

of any of the following troubles- ex-

cessive transmission gear wear, ..ans-

mission jumping out of gear, especial-

ly third gear, drive line vibration, ex-

cessive pilot bushing wear, noisy re-

lease bearing, or excessive clutch spin

time.

INSPECTION

1. With the clutch release bearing

removed, install the indicator pilot

tool shown in Fig. 1.

2.
Clean the faces of the flywheel

housing bolt bosses, and remove all

burrs, nicks, and paint from the

mounting face of the housing.

3.
Install the dial indicator on the

pilot and adjust the holder so the but-

ton will contact a circumference just

inside of the transmission mounting

holes.

4.
Push the flywheel forward to re-

move crankshaft end play. Set the dial

indicator face to read zero.

5.
Remove the spark plugs to alle-

viate compression.

6. Pull the engine crankshaft

through one revolution. The crank-

shaft must be held in the forward po-

sition while rotating it.

7. Note the indicator reading and

mark the maximum point of runout

on the face of the housing (Fig. 1).
8. Position the dial indicator to

check bore alignment (Fig. 1). The

bore must be clean and free of burrs,

nicks and paint.

9. Pull the crankshaft through one

revolution. Note the indicator reading

and mark the maximum point of run-

out on the face of the housing as

shown in Fig. 1.

10.
Remove the dial indicator from

the crankshaft and the housing.

11.
Select the Dia-L-lgner pilot

(Fig. 2) which will fit snugly in the

bore of the flywheel housing.

12.
Press the pilot into place on the

locator on the back of the dial.
13.
Position the Dia-L-lgner on the

face of the housing (Fig. 3) with the

pilot in the bore.

14.
Rotate the face runout arrow to

the positive face runout mark on the

housing.

15.
Without moving the face runout

arrow, rotate arrow A until it is at the

negative bore reading.

16.
Slide arrow A to register the

amount of bore runout on the .010-

line of the white scale. Use the

scale No. to coincide with the pilot

being used.
