3.
Inspect the rotor, rollers, cam

ring, pressure plate, cover, and bush-

ing in the pressure plate for wear or

scoring. If damaged, replacement of

the pump (less housing) is required.

4.
Make sure the inner faces of the

cover and the housing are free of

paint, nicks, or burrs. Check all fluid

passages for restrictions.

5.
Inspect the valving surfaces

(areas where the rotor and rollers con-

tact) for wear or scoring. Replace the

pressure plate or the cover if worn or

scored. Inspect the bushing in the

pressure plate for wear or scoring, and

replace the plate if necessary.

6. Inspect the control valve for

scores, nicks, or burred edges. Re-

place the valve if damaged. Do not dis-

assemble the valve. Check the valve

for free movement in the housing

bore.

7.
Inspect the tube seat in the hous-

ing. If damaged, remove it with an

E-Z-Out and install a new seat.

SHOCK ABSORBER CHECKS

All vehicles are equipped with hy-

draulic shock absorbers of the direct-

acting type and are nonadjustable and

nonrefillable. They cannot be repaired.
Before replacing a shock absorber,

check the action of the shock absor-

bers as follows:

ON VEHICLE TESTS

1.
Check the shock absorber to be

sure it is securely and properly in-

stalled. Check the shock absorber in-

sulators for damage and wear.

Replace any defective insulators and

tighten attachments to the specified

torque (on a shock absorber which in-

corporates integral insulators, replace

the shock absorbers).

2.
Inspect the shock absorber for

evidence of fluid leakage. A light film

of fluid is permissible. Be sure any

fluid observed is not from sources

other than the shock absorber.

Replace the shock absorber if leak-

age is severe.

3.
Disconnect the lower end of the

shock absorber. Extend and compress

the shock absorber as fast as possible,

using as much travel as possible.

Action should become smooth and

uniform throughout each stroke.

Higher resistance on extension than

on compression is a normal condition.

Faint swish noises are also normal.

Remove the shock absorber for a

bench test if action is erratic. If the
action is smooth, but the shock absor-

bers are suspected of being weak fol-

low step 4:

4.
Repeat step 3 on the mating

shock absorber installed on the oppo-

site side of the vehicle, and compare

results of both tests. If the action is

similar, it is unlikely that either shock

absorber is defective. Reconnect both

shock absorbers.

Replace the shock absorber having

the lower resistance. Ensure that the

part number of the replacement is the

same as that of the original shock ab-

sorber. The replacement shock absor-

ber resistance will appear to be higher

than either original due to initial fric-

tion of the rod seal.

BENCH TEST

With the shock absorber right side

up (as installed in vehicle), extend it

fully. Then turn the shock absorber

upside down and fully compress it.

Repeat this procedure at least three

times to ensure that any entrapped air

has been expelled. Now place the

shock absorber right side up in a vise,

and hand stroke the shock absorber as

described in On Vehicle Tests, step 3.

If action is not now smooth and uni-

form, install a new shock absorber.procarmanuals.com

is,
it is supported by bearings both in

front of and to the rear of the pinion

gear. Two opposed tapered roller

bearings support the pinion shaft in

front of the pinion gear with a col-

lapsible spacer for 8-3/4 inch or 9

inch ring gear, and a solid spacer used

with the 9 3/8 inch ring gear. A

straight roller (pilot) bearing supports

the pinion shaft at the rear of the pi-

nion gear. Pinion and ring gear tooth

contact is adjusted by adding or re-

moving shims from between the pinion

retainer and the carrier housing.

The differential assembly is mount-

ed on two opposed tapered roller

bearings, which are retained in the

carrier by removable caps. The entire

carrier assembly is bolted to the axle

housing.

Ball bearing assemblies (rear wheel

bearings) are pressed onto the outer

ends of the axle shafts and set in the

outer ends of the axle housing. These

bearings support the semi-floating

axle shafts at the outer ends. The

inner ends of the shafts spline to the

differential side gears. Bearing retain-

er plates hold the shafts in the hous-

ing. The left and right axle shafts are

not interchangeable, the left shaft

being shorter than the right.

LIMITED-SUP DIFFERENTIAL

The axle assembly, except for the

differential case and its internal com-

ponents, is identical to the convention-

al axle.

A constant-friction locking differen-

tial,
which employs clutch plates to

control differential action, is available

as optional equipment (Fig. 2).

Four steel clutch plates are locked

into the differential cover. Three

bronze, bonded clutch plates are

splined to a clutch hub which, in turn,
is splined to the left axle shaft. A

Belleville spring washer maintains a

constant pressure between the steel

and bonded clutch plates so that the

clutch is always engaged.

TRACTION-LOK

DIFFERENTIAL

The Traction-Lok (torque sensitive)

locking differential (Fig. 3) employs a

multiple disc clutch to control differ-

ential action. Shim(s), which control

side gear mounting distance, four

steel, four friction and one composite

plate (steel on one side and friction

material on the other) stacked on a

clutch hub, and four ear guides are

housed in the differential cover. Lo-

cated in the differential case between

the side gears is a one-piece pre-load

plate and block (four-pinion) and four

calibrated pre-load springs, which

apply an initial force to the clutch

pack. Additional clutch capacity is

derived from the side gear thrust

loads.
The four friction plates are

splined to the clutch hub which in turn

is splined to the left axle shaft, and

the eared steel plates are dogged to

the case; thus, the clutch is always en-

gaged.

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. 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.
