MAJOR REPAIR OPERATIONS

Disassembly and reassembly of the

unit and the subassemblies must be

made on a clean workbench. As in re-

pairing any hyldraulically operated

unit, cleanliness is of tftfiiost impor-

tance. Therefore, the bench, tools, and

parts must be kept clean at all times.

Thoroughly clean the exterior of the

gear with a suitable solvent and, when

necessary, drain as much of the hy-

draulic fluid from the gear as possible.

DISASSEMBLY INTO

SUB-ASSEMBLIES

1,
Mount the steering gear in a

vise.

2.
Rotate the end plug retaining

ring to place one end of the ring

opposite the hole in the housing.
3.
Working through the hole in the

housing (Fig. 3), unseat the retaining

ring then work it out of the groove

with a screwdriver.

4.
Rotate the input shaft in a coun-

terclockwise direction using a 3/4

inch, 12-point socket wrench to force

the end plug out of the housing. Do

not rotate the shaft any more than

necessary to remove the plug. Further

rotation will allow the balls to fall

from their circuit and allow the rack-

piston to become disengaged from the

sector shaft. Remove the O-ring from

the housing and discard it.

5.
Rotate the input shaft 1/2 turn

in a clockwise direction to draw the

piston inward.

6. Turn the end plug (Fig. 4) count-

erclockwise out of the piston with a

1/2 inch drive extension.
7.
Remove the lock nut from the

sector shaft adjustment screw. Discard

the nut.

8. Remove the four cover attaching

screws. Rotate the sector shaft adjust-

ment screw with an Allen wrench until

the cover is free of the housing. Re-

move the cover and the O-ring. Dis-

card the O-ring.

9. Turn the input shaft as required

to center the sector shaft teeth in the

housing.

10.
Tap the end of the sector shaft

with a soft-faced hammer to free it

from the housing.

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.

Too/-4235-C

E1032-D

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

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

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

1.
Place the inner side gear and

thrust washer in the differential case

(Fig. 52). Lubricate all parts liberally

with limited-slip axle lubricant during

assembly.

2.
With a soft-faced hammer, drive

the pinion shaft into the case only far

enough to retain a pinion thrust wash-

er and pinion gear.

3.
Place the second pinion and

thrust washer in position and drive

the pinion shaft into place. Carefully

line up the pinion shaft lock in holes.

4.
Install the pinion shaft lock pin.

The lock pin must not extend beyond

the surface of the case.

5. Insert two 2-inch 7/16 (NF)

bolts through the differential case

flange, and thread them three or four

turns into the ring gear as a guide in

aligning the ring gear bolt holes. Press

or tap the ring gear into position.

6. Clamp the differential case in a

soft-jawed vise. Install the differential

outer side gear on the differential pin-

ion gears. Place the clutch hub on

the side gear. Place the thrusi: washer

Plate Installation

Prior to clutch plate installation,

the friction bonded plates must be

soaked in C6AZ-19570-C (ESW-

M2C-104-A) differential lubricant for

approximately 1/2 hour. In addition,

the differential lubricant must be lib-

erally applied to all components to

be assembled.

1.
Place the clutch hub into posi-

tion in a soft-jawed vise.

2.
First, install a steel clutch plate

in the cavity of the differential case

opposite the ring gear and then a

bonded friction plate (Fig. 53). Any

tab on the steel plates can be inserted

into any cavity in the differential case,

however when the first steel plate is

inserted the others must be placed in

the same manner (Fig. 54) so the tabs

with slots line up. Install the remain-

ing plates: a steel plate, bonded fric-

tion plate, a steel plate, bonded fric-

tion plate and lastly a steel plate.

Make sure the bonded friction plate

inner-spline teeth properly engage the

hub spline.procarmanuals.com

Torque

High Torque

a. Insufficient lubricant on the

clutch plates.

b.
A clutch plate wedged in be-

tween the case halves.

c. An improperly centered Belleville

spring.

Low Torque

a. Weak Belleville spring.
b.
Improper amount of clutch

plates installed.

Under no circumstances should the

Belleville spring be ground down to

reduce torque. The torque required to

keep the side gear turning with new

clutch plates is 155 to 195 ft-lbs. On

reused clutch plates, the torque re-

quired is 75 ft-lbs minimun.

7.
If the differential bearings have

been removed, press them on as

shown in Figs. 49 and 50.

8. Install the side bearings on the

differential case, and install the case

in the carrier as described in steps 7

through 16 under Assembly and In-

stallation of Conventional Differential

Case. Adjust and check backlash be-

tween the ring gear and pinion as di-

rected under Differential Bearing Pre-

load Adjustments.

3.
Install the pinion thrust washers

and place the pinion gears on the side

gear; aligning the holes in the washers

and gears with the holes in the case.

4.
Install the center block so that

the shaft holes are aligned with the

holes in the pinion gears and case.

The center block has two machined

sides and two rough sides.

5.
With a brass drift, drive in the

long pinion shaft from the outside of

the case aligning the lock pin holes in

the shaft with the holes in the case.

The center block should be positioned

so the long shaft is driven through the

rough side and short shafts driven

through the machined side (Fig. 57).

6. With a suitable drift, install the

shaft lock pins. Make sure the pinion

and side gears move freely.

7.
Place the four pre-load springs in

the holes provided in the center block.

8. Position a pre-load plate over the

four springs, making sure the springs

are properly seated. The pre-load

plate straddles the center block over

its narrower or machined width.

9. Mount the differential cover in a

soft jawed vise or holding fixture.

10.
Insert shim(s) of 0.050 total

thickness in the cover cavity.

11.
Install the composite plate (fric-

tion material on one side and steel on

the opposite) on the back side of the

clutch hub with the friction material

against the hub; next, install a friction

plate, then steel, friction, stee, fric-

tion, steel, friction, and lastily a steel

plate (Figures 3 and 58). When new

clutch plates are used, soak the plates

in Ford Hypoid Lubricant (Ford Part

No.
C6AZ-19580-C), or equivalent lu-

bricant, for approximately 30 minutes

before installation.

12.
Place the clutch hub with the

clutch plates into the clutch ear cavi-

ties in the differential cover. Make

sure that the splines on the last fric-

ion plate are engaged on the hub.

13.
Obtain locally a 5/8 inch x

2 1/2 inch or 9/16 inch x 2 1/2

inch bolt, nut and two I 1/2 inch

outside diameter flat washers approx.

1/8 inch in thickness. These parts are

required to compress the clutch pack

in order to obtain the proper shim

selection.

Install a flat washer on the bolt,

and place the bolt through the clutch

hub.
Hold the bolt in position and

turn the cover over. Place a flat wash-

er on the bolt and then install the nut.

Be sure the washers are centered, and

torque the nut 10 to 15 ft-lbs (Fig.
