than removing the spool to replace the

dampener O-ring or replace the three

teflon seals or O-rings under the teflon

seals.

1.
Remove the cap to worm O-ring

and discard it (Fig. 17).

2.
Work the rear coil of spool

spring onto the stub shaft bearing sur-

face.
Do not pry on the valve body.

Slide the spring off the shaft.

3.
Extreme care must be used when

removing the valve spool. The diame-

tral clearance between the valve body

and the spool may be as low as 0.0004

inch. The slightest cocking of the

spool may jam it in the valve body.

a. To remove the valve spool, hold

the valve assembly in both hands with

the stub shaft pointing downward.

Push lightly on the valve spool with a

small rod by inserting the rod through

the openings in the end cap (Fig. 18)

until the spool is far enough out of the

valve so that it may be grasped by the

hand. Withdraw the spool with a

steady oscillating pull to prevent jam-

ming. If slight sticking occurs, make a

gentle attempt to reverse the with-

drawal procedure. If this does not free

the spool, it has become cocked in the

valve body bore. Do not attempt to

force the spool in or out if it becomes

cocked. In this case, continue to disas-

semble the valve assembly as follows

and return to the spool as described

later. Remove the stub shaft, torsion

bar, and end cap assembly by holding

the thumbs on the valve body as

shown in Fig. 18. Tap the torsion bar

lightly against the workbench. This

will dislodge the cap from the valve

body to cap pin. The stub shaft, tor-

sion bar and end cap assembly can

now be removed from the valve body.

b.
If the valve spool has become

cocked as described in step 3 above, it

can now be freed. By visual inspection

on a flat surface it can be determined

in which direction the spool is cocked.

A few very light taps with a light soft

plastic or raw-hide mallet should align

the spool in the bore and free it. Do

not tap with anything metallic. If

spool can be rotated, it can be re-

moved.

4.
Remove O-ring dampener seal

from the spool and discard it.

5.
Carefully cut the valve rings and

the ring back-up seals, remove and

discard them, providing the rings show

evidence of excessive wear. The valve

rings are made of filled teflon and it is

very unusual that replacement is re-

quired.

6. Remove the dampener O-ring

from the valve spool and discard it.procarmanuals.com

12.
Note the ball size stamped on

the rack-piston and install the next

size larger balls to increase the pre-

load. If no number is stamped on the

rack-piston, the original ball code size

was No. 7.

A change of one ball size larger will

increase the preload approximately

one in-lb. Final preload on replace-

ment balls should be 2-3 in-lbs.

Remove the valve assembly from

the worm and the rack-piston from

the vise.

13.
Insert Tool T65P-3D517-A into

the plug end of the rack and piston to

contact the worm shaft (Fig. 22).

Apply pressure on the tool while ro-

tating the worm shaft out of the pis-

ton and rack. Leave the tool in place

until the piston is installed in the

1.
Secure the steering gear housing

in a vise.

2.
Lubricate the worm shaft, lower

thrust bearing, and races; then posi-

tion the thrust bearing and races on

the worm.

Align the valve body drive pin on

the worm, with the narrow pin slot in

the valve body. Be sure O-Ring seal

between the valve body and the worm

head is installed.

3.
Position the valve assembly and

the worm shaft in the housing as a

unit (Fig. 23). Do not push against the

stub shaft as this could cause the stub

shaft and cap to pull out of the valve

body, allowing the spool seal to slip

into valve body fluid grooves. Install

the valve assembly by pushing on the

outer diameter of the valve body hous-

ing with the finger tips. Be sure that

the teflon rings are not binding inside

the housing. The valve assembly is

correctly seated when the fluid return

hole in the gear housing is fully vis-

ible.

4.
Place the tool shown in Fig. 24

over the end of the stub shaft.

5.
Lubricate a new adjuster plug

O-ring and install it in the adjuster

plug groove.

6. Install the adjuster plug over the

end of the stub shaft and tighten it

3A537-B.

7.
Install the adjuster plug locknut

loosely on the plug.

8. Tighten the adjuster plug with

wrench J7624 while rotating the input

shaft. As soon as additional drag is

noted, back the adjuster plug off 1/8

turn. Measure the input shaft drag

with an in-lb torque wrench.

9. Tighten the adjuster plug (Fig.

25) to obtain a 1-3 in-lb preload in ex-

cess of the drag that was measured

previously. Tighten the adjuster plug

lock nut and recheck the thrust bear-

ing preload. Total preload must not

exceed 8 in-lbs.

10.
Install Tool T65P-3805-A in

the steering gear housing. Position the

rack-piston as shown in Fig. 26. Be

sure that Tool T65P-3D517-A is con-

tacting the worm shaft. Push the

rack-piston inward until it contacts

the worm shaft while keeping pressure

applied to Tool T65P-3D517-A. Turn

the stub shaft clockwise until the

middle rack groove in the rack-piston

is aligned with the center of sector

shaft roller bearing. Remove the tool

from the housing.

11.
Lubricate a new O-ring with

C1AZ-19582-A and position it in the

sector shaft cover.

12.
Thread the sector shaft cover

on the adjusting screw until it bottoms

then back it off 1 1/2 turns.

13.
Install the sector shaft so that

the center gear tooth meshes with the

center groove in the rack-piston. Be

sure that the cover O-ring is in place

before pushing the cover down on the

IDENTIFICATION

The AXLE code on the vehicle

Warranty Plate (Fig. 1) identifies the

rear axle type (conventional or

limited-slip differential) and gear

ratio.

A metal tag (Fig. 2) stamped with

the model designation and gear ratio

is secured to one of the rear cover-

to-housing bolts (integral carrier-type)

or to one of the carrier-to-housing

bolts (removable carrier-type).

The spaces on the top line provide

the axle model identification code.

This code, such as WDT-AN4,

WDC-AS4, WEG-C2, etc. indicates a

specific combination of the following

factors: conventional or limited slip

differential; diameter of ring gear;

small or large wheel bearings; and the

gear ratio. Refer to the specifications

group of this manual for the car-line

rear axle ratios, gear and code
identif-

ication.

The second line on the tag is used

for gear ratio, the production date

code and the production plant identifi-

cation code.
It is important to use the model

designation when obtaining correct re-

placement parts.

LIMITED-SUP
OR

TRACTION-LOK DIFFERENTIAL

OPERATION CHECK

A limited-slip or Traction-Loc dif-
ferential can be checked for proper

operation without removing the carrier

from the axle housing.

Jack up one rear wheel and remove

the wheel cover. Install the tool on the

axle shaft flange studs as shown in

If the tooth pattern indicates a change

in shim thickness, follow the proce-

dure under Pinion Location.

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.

13).

place the companion flange and check

the runout. If necessary, rotate the

new flange on the pinion shaft until an

acceptable runout is obtained.

If excessive runout is still evident

after replacement of the companion

flange, it will be necessary to replace

the ring and pinion gear, and repeat

the above checks until runout is within

specifications.

ADJUSTMENT

Two separate adjustments affect pin-

Individual differences in matching

the differential housing and the gear

set require the use of shims to locate

the pinion for correct contact with the

ring gear.

When adjusting either type axle,

shim thickness should be increased or

reduced only as indicated by the tooth

cone (Fig. 12). When adjusting this

type axle, increasing shim thickness

moves the pinion toward the ring

gear; reducing shim thickness moves

the pinion away from the ring gear

(Fig. 12).

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

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.

FIG. 4—Removing Axle Shaft

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
