Place the dust seal in the hous-

ing with the dished side (rubber side)

facing out. Drive the dust seal into

place with the tool shown in Fig. 11.

the seal must be located behind the

undercut in the input shaft when it is

installed.

Worm and Valve

1.
Remove the snap ring from the

end of the actuator.

2.
Slide the control valve spool

(Fig. 6) off the actuator.

3.
Install the valve spool evenly and

slowly with a slight oscillating motion

into the flanged end of valve housing

with the Valve identification groove

between the valve spool lands out-

ward, checking for freedom of valve

movement within the housing working

area. The valve spool should enter the

housing bore freely and fall by its own

weight.

4.
If the valve spool is not free,

check for burrs at the outward edges

of the working lands in the housing

and remove with a hard stone.

5.
Check the valve for burrs and if

burrs are found, stone the valve in a

radial direction only. Check for free-

dom of the valve again.

6. Remove the valve spool from the

housing.

7.
Slide the spool onto the actuator

making, sure that the groove in the

spool annulus is toward the worm.

8. Install the snap ring to retain the

spool.

9. Check the clearance between the

spool and the snap ring. The clearance

should be between 0.002-0.005 inch. If

the clearance is not within these lim-

its,
select a snap ring that will allow a

clearance of 0.003 inch.

REMOVABLE CARRIER

TYPE AXLE

The shim location for the removable

carrier type axle is between the pinion

retainer and the carrier (Fig. 13).

When adjusting this type carrier re-

ducing shim thickness will move the

pinion toward the ring gear; increas-

ing shim thickness will move the pi-

nion away from the ring gear (Fig.

new flange on the pinion shaft until an

acceptable runout is obtained.

If excessive runout is still evident

after replacement of the companion

moves the pinion toward the ring

gear; reducing shim thickness moves

the pinion away from the ring gear

(Fig. 12).

BACKLASH AND DIFFERENTIAL

ADJUSTMENTS (ALL AXLES)

On a Light-Duty (WER) Axle, it is

necessary to remove the rear axle

shafts prior to performing the adjust-

ment procedures. Refer to Rear Axle

Shaft Wheel Bearing and Oil Seal Re-

placement—Light-Duty (WER), Axle,

Part 4-4, Section 2.

To secure a more uniform control

of differential side bearing preload in

service repairs, a dial indicator set-up

such as shown in Fig. 12 is used.

In both types of axle (Fig. 11 and

12),
the ring gear is moved away from

or toward the pinion as described in

the following procedure.

1.
Remove the adjusting nut locks,

loosen the differential bearing cap

bolts,
then torque the bolts to 15 ft-lbs

on integral carrier type axle; 20 ft-lbs

on removable carrier type axles before

making adjustments.

2.
The left adjusting nut is on the

ring gear side of the carrier. The right

nut is on the pinion side. Loosen the

right nut until it is away from the cup.

Tighten the left nut until the ring gear

is just forced into the pinion with

0.000 backlash then rotate the pinion

several revolutions to be sure no bind-

ing is evident. (Recheck the right nutprocarmanuals.com

CLEANING AND INSPECTION

INSPECTION BEFORE

DISASSEMBLY OF CARRIER

(ALL AXLES)

The differential case or carrier

should be inspected before any parts

are removed from it. These inspec-

tions can help to find the cause of the

trouble and to determine the correc-

tions needed.

Mount the carrier in the holding

fixture shown in Fig. 15. Wipe the lu-

bricant from the internal working

parts,
and visually inspect the parts

for wear or damage.

Tool-T57L-500-A

FIG. 15
— Bench
Fixture for

Carrier Overhaul—Typical

Rotate the gears to see if there is

any roughness which would indicate

damaged bearings or chipped gears.

Check the gear teeth for scoring or

signs of abnormal wear.

Set up a dial indicator (Fig. 16) and

check the backlash at several points

around the ring gear. Backlash should

be within specifications.
If no obvious defect is noted, check

the gear tooth contact.

To check the gear tooth contact,

paint the gear teeth with the special

compound furnished with each service

ring gear and pinion. A mixture that

is too wet will run and smear. Too dry

a mixture cannot be pressed out from

between the teeth.

As shown in Fig. 17, rotate the ring

gear (use a box wrench on the ring

gear attaching bolts for a lever) five

complete revolutions in both directions

or until a clear tooth contact pattern

is obtained.

7—Checking Gear Tooth

Contact—Typical

Certain types of gear tooth contact

patterns on the ring gear indicate in-

correct adjustment. Noise caused by

incorrect adjustment can often be cor-

rected by readjusting the gears. Ac-

ceptable patterns and the necessary

corrections are explained under Tooth

Contact Pattern Check in Section I.

Gear tooth runout can sometimes

be detected by an erratic pattern on

the teeth. However, a dial indicator

should be used to measure the runout

of the back face of the ring gear as

shown in Fig. 18. If this runout ex-

ceeds specifications, disassemble the

carrier and replace necessary parts as

indicated in Part 4-2, Section 4 and

Part 4-3, Section 4.
1699-A

FIG. 18 -Checking Ring Gear

Runout—Typical

Loosen the differential bearing cap

bolts,
and then torque them to 25 ft-

lbs.
Remove the adjusting nut locks.

Carefully loosen one of the adjusting

nuts to determine if any differential

bearing preload remains. If any pre-

load remains, the differential bearings

may be re-used, provided they are not

pitted or damaged.

INSPECTION AFTER

DISASSEMBLY OF CARRIER

(ALL AXLES)

Thoroughly clean all parts. Syn-

thetic seals must not he cleaned, soak-

ed or washed in cleaning solvents.

Always use clean solvent when clean-

ing hearings. Oil the bearings im-

mediately after cleaning to prevent rust-

ing. Inspect the parts for defects.

Clean the inside of the carrier before

rebuilding it. When a scored gear set

is replaced, the axle housing should he

washed thoroughly and steam cleaned.

This can onl\ be done effectively if the

axle shafts and shaft seals are re-

moved from the housing. Inspect indi-

vidual parts as outlined below.

GEARS

Examine the pinion and ring gear

IN-VEHICLE ADJUSTMENTS AND REPAIRS

REAR AXLE SHAFT, WHEEL

BEARING AND OIL SEAL

REPLACEMENT

The rear axle shafts, wheel bear-

ings,
and oil seal can be replaced

without removing the differential as-

sembly from the axle housing.

REMOVAL OF

AXLE SHAFT

Synthetic wheel bearing seals are

used in production only. Removal and

insertion of rear axle shafts must be

performed with caution. The entire

length of the shaft (including spline)

up to the seal journal must pass

through the seal without cutting of the

seal element during axle removal or

installation will result in early seal fai-

lure.
Leather seals only will be used as

service replacement for synthetic

wheel bearing seals.

1.
Remove the wheel cover, wheel

and tire from the brake drum.

2.
Remove the nuts that secure the

brake drum to the axle shaft flange,

then remove the drum from 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. 4). The brake backing

plate must not be dislodged. Install

one nut to hold the plate in place after

the axle shaft is removed.

REMOVAL OF REAR

WHEEL BEARING AND

SEAL

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvents.

Removal of the wheel bearings from

the axle shaft makes them unfit for

further use.

1.
On all models except Ford, Mer-

cury or Meteor, 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. 5). It will then slide off easily.
E 1731-A

FIG. 5—Removing Rear Wheel

Bearing Retainer Ring

On Ford, Mercury and Meteor mo-

dels,
it is necessary to first drill a 1/4

inch hole not more than 5/16 inch

deep in the retainer ring surface bef-

ore using the cold chisel.

2.
Remove the bearing from the

axle shaft with the tool shown in Fig.

6 or Fig. 7.

3.
Whenever a rear axle shaft is re-

placed, the oil seal must be replaced.

Remove the seal with Tool 1175-AB

and a slide hammer (Fig. 8). If new

leather-type wheel bearing service

seals are to be installed, soak new oil

seals in SAE 10 oil for 1/2 hour

before installing.

INSTALLATION OF REAR

WHEEL BEARING AND

SEAL

1.
Inspect the machined surface 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 twist. Care-

fully remove any burrs or rough spots.

Replace worn or damaged parts.

2.
Lightly coat wheel bearing bores

with axle lubricant.

3.
Place the retainer plate on the

axle shaft, and press the new wheel

bearing on the shaft with the tool

shown in Fig. 6 or Fig. 9. Do not at-

tempt to press on both the bearing

and the inner retainer ring at the same

time.

4.
Using the bearing installation

tool (Tool 4621-A or 4234-4), press

the bearing inner retainer ring on the

shaft until the retainer seats firmly

against the bearing. On Ford, Mercu-

ry, or Meteor models, before assem-

bling the retainer onto the axle shaft,

the shaft journal and the inside di-
ameter of the retainer should be wiped

clean with a dry cloth. These parts

must not be degreased or lubricated.

5. Rear wheel oil seals with synthe-

tic sealing elements have been incor-

porated in production only. However,

leather seals only will be used as re-

placements for the synthetic sealing

elements. Install the new oil seal with

the tools shown in Figs. 10 and 12. Be

sure the new seal has been soaked in

SAE 10 oil for 1/2 hour before in-

stalling it. Wipe a small amount of oil

resistant sealer on the outer edge of

the seal before it is installed. Do not

put sealer on the sealing lip.

INSTALLATION OF

AXLE SHAFT

1.
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.

2.
Install the bearing retainer plate

and the nuts that secure it. Torque the

nuts to specifications.

3.
Install the brake drum and the

drum attaching (Tinnerman) nuts.

4.
Install the wheel and tire on the

drum. Install the wheel cover.

DRIVE PINION OIL SEAL

REPLACEMENT

COLLAPSIBLE SPACER

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvent.

The drive pinion oil seal can be re-

placed without removing the differen-

tial carrier assembly from the axle

housing.

1.
Raise the vehicle and install

safety stands. Remove both 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. 11). 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
