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.

casting with a drift. Install the new

cups with the tool shown in Fig. 22.

Make sure the cups are properly seat-

ed in their bores. If a 0.0015-inch feel-

er gauge can be inserted between a

cup and the bottom of its bore at any

point around the cup the cup is not

properly seated.

Whenever the cups are replaced, the

cone and roller assemblies should also

be replaced.

DRIVE PINION AND GEAR

SET

Individual differences in machining

the carrier casting and the gear set re-

quire a shim between the pinion rear

bearing cone and the pinion gear to

locate the pinion for correct tooth

contact with the ring gear.

When replacing a ring gear and pin-

ion it should be noted that the original

factory installed shim is of the correct

thickness to adjust for individual vari-

ations in both the carrier casting di-

mension and in the original gear set

dimension; therefore, to select the cor-

rect shim thickness for the new gear
set to be installed, follow these steps:

1.
With a micrometer, measure the

thickness of the original shim removed

from the axle and use the same thick-

ness upon installation of the replace-

ment carrier assembly or drive pinion.

2.
If further shim change is neces-

sary, it will be indicated in the tooth

pattern check.

3.
If the original shim is lost, sub-

stitute a nominal shim for the original

and use the tooth pattern check to de-

termine if further shim changes are re-

quired. Nominal shim thickness is in-

dicated in Part 4-5, Specifications.

A new ring gear and pinion should

always be installed in an axle as a

matched set (never separately). Be

sure the same identifying (matching)

number, painted in white, appears on

the bolt hole face of the ring gear and

on the head of the drive pinion

(Fig. 23).

4.
After determining the correct

shim thickness as explained in the

foregoing steps, install the new pinion

and ring gear as outlined under As-

sembly.

DIFFERENTIAL CASE,

BEARINGS, AND RING

GEAR

If the ring gear runout checK (be-

fore disassembly) exceeded specifica-

tions,
the condition may be caused by

a warped gear, a defective case, or ex-

cessively worn differential bearings.

To determine the cause of excessive

runout proceed as follows:

1.
Assemble the two halves of the

differential case together without the

ring gear, and press the two differen-

tial side bearings on the case hubs.

2.
Place the cups on the bearings

and set the differential case in the car-

rier.
3.
Install the bearing caps and ad-

justing nuts as outlined in steps 11

thru 14 under Installation of Drive

Pinion and Differential Case in this

section.

4.
Tighten the right nut two notches

beyond the position where it first con-

tacts the bearing cup. Rotate the dif-

ferential case several revolutions in

each direction while the bearings are

loaded to seat the bearings in their

cups.
This step is important.,

5.
Again loosen the right nut to re-

lease the preload. Check to see that

the left nut contacts the bearing cup.

Using the dial indicator set-up shown

in Fig. 10, Part 4-1, adjust the preload

to 0.008 to 0.012 case spread for new

bearings or 0.005 to 0.008 for the

original bearings, if reused.

6. Check the runout of the differen-

tial case flange with a dial indicator.

If the runout does not now exceed

specifications, install a new ring gear.

If the runout still exceeds specifica-

tions,
the ring gear is true and the

trouble is due to either a defective

case or worn bearings.

7.
Remove the differential case

from the carrier and remove the side

bearings from the case.

8. Install new bearings on the case

hubs,
and again install the differential

assembly in the carrier without the

ring gear.

9. Check the case runout again with

the new bearings. If the runout is now

within limits, the old bearings were

excessively worn. Use the new bear-

ings for assembly. If the runout is still

excessive, the case is defective and

should be replaced.

ASSEMBLY

Refer to Part 4-1 for Cleaning and

Inspection before starting assembly

operations.

ASSEMBLY OF

DIFFERENTIAL CASE

1.
Lubricate all the differential

parts with axle lubricant, before they

are installed in the case.

2.
Place the side gears and thrust

washers in the case.

3.
Place the two pinion gears and

thrust washers exactly opposite each

other in the case openings and in

mesh with the side gears.

4.
Turn the pinions and thrust

washers until the holes in the pinion

gears align with the pinion shaft holes

in the case.

5.
Start the pinion shaft into the

3.
Lubricate
the
pinion rear bearing

with axle lubricant.

4.
Lubricate
the
pinion front bear-

ing cone
and
place
it in the
housing.

5.
Install
a new
pinion
oil
seal
in

the carrier casting (Fig.
11).

6. Insert
the
drive pinion shaft

flange into
the
seal
and
hold
it
firmly

against
the
pinion front bearing cone.

From
the
rear
of the
carrier casting,

insert
the
pinion shaft into
the
flange.

7.
Start
a new
pinion shaft
nut.

Hold
the
flange with
the
tool shown
in

Fig.
9 and
tighten
the
pinion shaft

nut.
As the
pinion shaft
nut is
tight-

ened,
the
pinion shaft
is
pulled into

the front bearing cone
and
into
the

flange.

As
the
pinion shaft
is
pulled into

the front bearing cone, pinion shaft

end play
is
reduced. While there
is

still
end
play
in the
pinion shaft,
the

flange
and
cone will
be
felt
to
bottom.

This indicates that
the
bearing cone

and flange have bottomed
on the col-

lapsible spacer.

From this point,
a
much greater

torque must
be
applied
to
turn
the

pinion shaft
nut,
since
the
spacer must

be collapsed. From this point, also,

the
nut
should
be
tightened very slow-

ly
and the
pinion shaft
end
play

checked often,
so
that
the
pinion bear-

ing preload does
not
exceed
the
limits

(Fig.
6).

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

the
marked teeth
on the
ring

gear
as
shown

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

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

DESCRIPTION

A light-duty, integral-carrier, con-

ventional-type rear axle assembly (Fig.

1) is used in Ford and Meteor passen-

ger vehicles equipped with 240-IV and

302 2V engines and related transmis-

sions.
The axle (model WER) incor-

porates the following features:

The hypoid gear set consists of an

8.50 inch diameter ring gear and an

overhung drive pinion which is sup-

ported by two opposed tapered roller

bearings. A drive pinion pilot bearing

is not used in this axle.

The differential carrier is the non-

removable type, with a stamped bolt-

on cover. The filler hole is tapped in
the front portion of the carrier casting

and uses a
1/2-14
tapered pipe plug

with a 3/8 inch square female drive. A

bumper pad is machined on the pinion

nose portion of the carrier. The rub-

ber bumper is mounted on the vehicle

underbody.

The differential case is a one-piece

design, with openings allowing assem-

bly of the internal components and lu-

bricant flow. The differential pinion

shaft is retained with a threaded bolt

(lock) assembled to the case.

The axle housing assembly consists

of tube assemblies pressed and welded

into the differential casting. The brake
backing plate retainer is welded in-

board of the outer edges of the tubes,

and allows assembly of the backing

plate, independent of the axle shafts.

The roller-type wheel bearings have

no inner race, and contact the bearing

journals of the axle shafts.

The axle shafts do not use an inner

or outer bearing retainer. They are

held in the axle by means of C-locks,

positioned in a slot on the splined end.

These C-locks also fit into a machined

recess in the differential side gears

within the differential case. There is

no retainer bolt access hole in the axle

shaft flange.
