DESCRIPTION

FRONT WHEEL ASSEMBLY

Each front wheel
and
tire
is
bolted

to
its
respective front
hub and
brake

drum
or
rotor assembly.
Two
opposed

tapered roller bearings
are
installed
in

each
hub. A
grease retainer
is in-

stalled
at the
inner
end of the hub to

prevent lubricant from leaking into

the drum
or on the
rotor.
The
entire

assembly
is
retained
to its
spindle
by

the adjusting
nut, nut
lock
and
cotter

pin (Figs.
1 and 2).

REAR WHEEL ASSEMBLY

The rear wheel
hub and
brake drum

assembly
is
attached
to
studs
on the

rear axle shaft flange
by
three speed

nuts.
The
wheel
and
tire mounts
on

the same rear axle shaft flange studs

and
is
held against
the hub and
drum

by
the
wheel nuts.
The
rear wheel

bearing
is
pressed onto
the
axle shaft

just inside
the

LIFE GUARD TIRE

The Goodyear Power Cushion Tire

(available
on
Thunderbird, Lincoln

and Continental Mark
III
models)
fit-

ted with
the
Life Guard Safety Spare
provides
a
tire within
a
tire with
two

separate
air
chambers
(Fig.
3). If the

outer tire casing should
be
punctured

or otherwise damaged causing
it to go

flat,
the
Life Guard Safety Spare will

carry
the
load
of the
vehicle
and
will
allow driving
at
speeds
up to 40 mph

with good control
up to a
distance
of

40 miles.
A
Safety-Signal built into

the Life Guard tread produces
a
lope

or vibration indicating
the
outer tire

has lost pressure.

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

steering linkage.
If the
adapters
are

placed under
the
crossmember,
a
piece

of wood (2x4x16 inches) should
be

placed
on the
hoist channel between

the adapters. This will prevent
the

adapters from damaging
the
front
sus-

pension struts.

FRONT WHEEL BEARING

ADJUSTMENT

The front wheel bearings should
be

adjusted
if the
wheel
is

obtain normal brake lining to rotor

clearance and restore normal brake

pedal travel.

BALANCING LIFE

GUARD TIRE

Tires fitted with the Life Guard

Safety Spare are balanced in the same

manner as conventional tires. If an ex-

cessive out of balance condition exists

the following procedure can be used to

correct the condition:

1.
Remove the core housing and de-

flate both air chambers.

2.
Install the core housing.

3.
Unseat the beads of tire with the

bead breakers away from the valve

stem as shown in Fig. 5.

F 1383

FIG. 5—Breaking Top Bead of

Tire From Wheel Rim
4.
Rotate tire casing 90 degrees on

the wheel rim.

5.
Rotate the tire casing back and

forth on the rim to center the valve.

6. Inflate both chambers of the tire

following steps 13 through 15 of the

Tire Installation procedure.

7.
Balance the tire in the normal

manner.

CORRECTING VIBRATION

AND SHAKE-

LIFE GUARD TIRE

The condition of excessive vibration

and shake is generally the result of an

incorrect pressure relationship between

the inner and outer air chambers that

may cause the life guard to shift posi-

tion within the tire. The following

procedure should be used to correct

vibration and shake conditions:

1.
Check pressure of the inner and

outer air chambers on all four tires.

2.
If the inner chamber has at least

five psi more pressure than the outer

chamber the pressures should be ad-

justed and the tires rebalanced if nec-

essary.

3.
If the pressures of the inner and

outer air chambers are equal the Air

Container is leaking. To repair the

leaking air container the recommend-

ed procedures for the removal, repair

of air container, mounting, and bal-

ancing should be followed.

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 (2x4x16 inches) should

be placed on the hoist channel be-

tween the adapters. This will prevent

the adapters from damaging the front

suspension struts.

10.
All old grease should be com-

pletely cleaned from the bearings and

surrounding surfaces before repacking

them with new grease (C1AZ-

19590-B). The new lithium base grease

is not compatible with sodium base

grease which may have been present

on the bearing surfaces. Pack the

bearing cone and roller assemblies

with wheel bearing grease. A bearing

packer is desirable for this operation.

If a packer is not available, work as

much lubricant as possible between

the rollers and cages. Lubricate the

cone surfaces with grease.

11.
Place the inner bearing cone

and roller assembly in the inner cup,

Apply a light film of grease to the

lip(s) of the grease retainer and install

the new grease retainer with the rev-

erse end of the tool shown in Fig. 6.
Be sure that the retainer is properly

seated.

Install the outer bearing cone

and roller assembly and the flat wash-

er on the spindle, then install the ad-

justing nut (Fig. 1).

15.
Adjust the wheel bearings as

outlined in Section 2, and install a

new cotter pin. Bend the ends of the

cotter pin around the castellations of

the nut lock to prevent interference

with the radio static collector in the

grease cap. Install the grease cap.

16.
Install the hub cap or wheel

cover.

DISC BRAKES

1.
Raise the vehicle until the wheel

and tire clear the floor.

2.

8. Clean the lubricant off the inner

and outer bearing cups with solvent

and inspect the cups for scratches,

pits,
excessive wear, and other dam-

age.
If the cups are worn or damaged,

remove them with Tool T69L-1102-A

(Fig. 13).

On Lincoln Continental models, re-

move worn or damaged cups with the

tools shown in Fig. 16.

9. Thoroughly clean the inner and

outer bearing cones and rollers with

computer solvent, and dry them

thoroughly. Do not spin the bearings

dry with compressed air.

Inspect the cones and rollers for

wear or damage, and replace them if

necessary. The cone and roller assem-

blies and the bearing cups should be

replaced as a set if damage to either is

encountered.

10.
Thoroughly clean the spindle

and the inside of the hub with solvent

to remove all old lubricant.

Cover the spindle with a clean

cloth, and brush all loose dust and

dirt from the dust shield. To prevent

getting dirt on the spindle carefully re-

move the cloth from the spindle.

11.
If the inner and/or outer bear-

ing cup(s) were removed, install the

replacement cup(s) in the hub with the

tools shown in Fig. 17. Be sure to seat

the cups properly in the hub.

12.
Pack the inside of the hub with

the specified wheel bearing grease.

Add lubricant to the hub only until

the grease is flush with the inside di-

ameter of both bearing cups.

It is important that all old grease

be removed from the wheel bearings

and surrounding surfaces because the

new Lithium base grease C1AZ-

19590-B is not compatible with Sodi-

um base grease which may already be

present on the bearing surfaces.

REMOVAL AND INSTALLATION

CARRIER ASSEMBLY

REMOVAL

1.
Raise the vehicle on a hoist and

remove the two rear wheels and tires.

2.
Remove the two brake drums (3

Tinnerman nuts at each drum) from

the axle shaft flange studs. If diffi-

culty is experienced in removing the

drums, remove the brake adjuster

knockout slug or rubber plug (if so

equipped) and back off the brake

shoes.

3.
Working through the hole pro-

vided in each axle shaft flange, re-

move the nuts that secure the rear

wheel bearing retainer plate. Pull each

axle shaft assembly out of the axle

housing using axle shaft remover,

Tool 4235-C. (Fig. 4). Care must be

exercised to prevent damage to the

production-type synthetic oil seal, if so

equipped. Any roughing or cutting of

the seal element during removal or in-

stallation can result in early seal fail-

ure.
Install a nut on one of the brake

backing plate attaching bolts to hold

the plate to the axle housing after the

shaft has been removed. Whenever a

rear axle shaft is replaced, the wheel

bearing oil seals must be replaced.

Remove the seals with tool 1175AB.

4.
Make scribe marks on the drive

shaft end yoke and the axle U-joint

flange to insure proper position at as-

sembly. Disconnect the drive shaft at

the rear axle U-joint. Hold the cups

on the spider with tape. Mark the

cups so that they will be in their orig-

inal position relative to the flange

when they are assembled. Remove the

drive shaft from the transmission ex-

tension housing. Install an oil seal re-

placer tool in the housing to prevent

transmission leakage. Refer to the

transmission group for the appropriate

tool.

5.
Clean area around carrier to

housing surfaced with a wire brush and

wipe clean, to prevent dirt entry into

the housing. Place a drain pan under

the carrier and housing, remove the

carrier attaching nuts, and drain the

axle.
Remove the carrier assembly

from the axle housing.

INSTALLATION

Synthetic production-type wheel

bearing seals must not be cleaned,

soaked or washed in cleaning solvent.

1.
Clean the axle housing and

shafts using kerosene and swabs. To

avoid contamination of the grease in
the sealed ball bearings, do not allow

any quantity of solvent directly on the

wheel bearings. Clean the mating sur-

faces of the axle housing and carrier.

2.
Position the differential carrier

on the studs in the axle housing using

a new gasket between carrier and

housing. Install the carrier-to-housing

attaching nuts, and torque them to

specifications.

3.
Remove the oil seal replacer tool

from the transmission extension hous-

ing. Position the drive shaft so that

the front U-joint slip yoke splines to

the transmission output shaft.

4.
Connect the drive shaft to the

axle U-joint flange, aligning the scribe

marks made on the drive shaft end

yoke and the axle U-joint flange dur-

ing the removal procedure. Install the

U-bolts and nuts and torque to speci-

CONTROL PRESSURE

CHECK

When the vacuum diaphragm unit is

operating properly and the downshift

linkage is adjusted properly, all the

transmission shifts (automatic and

kickdown) should occur within the

road speed limits specified in Part 7-5.

If the shifts do not occur within

limits or the transmission slips during

shift point, the following procedure is

suggested to determine engine, trans-

mission, linkage, vacuum diaphragm

unit or valve body problems.

1.
Using the automatic transmis-

sion tester (Fig. 4), attach the tachom-

eter to the engine and the vacuum

gauge to the transmission vacuum line

at the vacuum unit (Fig. 5).

4.
Adjust the engine idle speed lo

the specified rpm. If the engine idle

speed cannot be brought within limits

by adjustment at the carburetor idle

adjustment screw, check the throttle

and downshift linkage for a binding

condition. If the linkage is satisfacto-

ry, check for vacuum leaks in the

transmission diaphragm unit (Fig. 8

or 9) and its connecting tubes and

hoses.
Check all other vacuum oper-

ated units (such as the power brake)

for vacuum leaks.
