POWER STEERING-

PRELIMINARY TESTS

The following preliminary checks

should always be made before per-

forming any operations.

AIR BLEEDING

Air in the power steering system

(shown by bubbles in the fluid) should

be bled. After making sure that the

reservoir is filled to specification (the

fluid must be at normal operating

temperature when the check is made),

turn the steering wheel through its full

travel three or four times. Do not hold

the wheels against their stops. Re-

check the fluid level.

CHECK FLUID LEVEL

Run the engine until the fluid is at

normal operating temperature. Then

turn the steering wheel all the way to

the left and right several times, and

shut off the engine.

Check the fluid level in the power

steering reservoir. The level must show

on the cross hatching between the bot-

tom of the dipstick and the full mark

(Fig. 1). If the level is low, add

enough automatic transmission fluid

C1AZ-19582-A to raise the level to

the F mark on the dipstick. Do not

overfill the reservoir.

CHECK PUMP BELT

If the pump belt is broken, glazed,

or worn, replace it with a new belt.

Use only the specified type of belt.

Refer to Part 3-13 for belt adjustment

procedure.

CHECK FOR FLUID

LEAKS

With the engine idling, turn the

steering wheel from stop to stop sever-

al times. Check all possible leakage

points. Tighten all loose fittings, and

replace any damaged lines or defective

seats.

CHECK TURNING EFFORT

With the front wheels properly al-

igned and tire pressures correct, check

the effort required to turn the steering

wheel.

With the vehicle on dry concrete,

set the parking brakes.

2.
With the engine warmed up and

running at idle speed, turn the steering

wheel to the left and right several

times to warm the fluid.

3.
Attach a pull scale to the rim of

the steering wheel. Measure the pull

required to turn the wheel one com-

plete revolution in each direction. The

effort required to rotate the steering

wheel should not exceed specifications

given in Part 3-13.

lined below should be followed to de-

termine the cause of the trouble.

PUMP FLOW TEST

1.
Depending on the equipment

present on the vehicle (air condition-

ing, power brakes, standard transmis-

sion),
one of the following options

may be used to connect the pump

pressure and return hoses to the test

tool (T56L-3361O-D and T68L-

33610-A):

a. Disconnect the pressure and re-

turn lines at the power steering pump

(Fig. 2). Obtain a power steering re-

turn hose from stock and connect the

end with the fitting to the output fit-

ting of the tool using the
5/8-18
SAE

female, 1/4 N.P. thread male fitting

provided. The end of the stock hose

(without the fitting) should be con-

nected to the return tube of the pump.

Connect the pressure hose from the

tool to the outlet fitting of the pump.

b.
Disconnect the pressure line at

the pump and connect the pressure

line from the test tool to the outlet fit-

ting of the pump. Disconnect the re-

turn line at the gear and connect it to

the output fitting of the tool, using the

5/8-18
SAE female, 1/4 N.P. thread

male fitting provided.

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.

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

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

housing. Install an oil seal replacer

A page number indicates that the item is for the vehicle listed at the head of the column.

N/A indicates that the item is not applicable to the vehicle listed.

Three different three-speed trans-

missions are used. The C4 Automatic,

C6 Automatic and the FMX Auto-

matic. Part 7-1 covers testing, com-
mon adjustments and repairs, and

cleaning and inspection for the three

types of transmissions. Where there
are differences in procedures or speci-

fications, the type of transmission af-

fected will be designated.

l
AUTOMATIC TRANSMISSION TESTS

When diagnosing transmission

problems, refer to the Ford Car and

Truck Diagnosis Manual for the de-

tailed information on the items that

could be causing the problem.

The following preliminary checks

should be made before proceeding

with other diagnosis checks.

TRANSMISSION FLUID LEVEL

CHECK

1.
Make sure that the vehicle is

standing level. Then firmly apply the

parking brake.

2.
Run the engine at normal idle

speed. If the transmission fluid is cold

run the engine at fast idle speed

(about 1200 rpm) until the fluid reach-

es its normal operating temperature.

When the fluid is warm, slow the en-

gine down to normal idle speed.

3.
On a vehicle equipped with a

vacuum brake release, disconnect the

release line and plug the end of the
line;
otherwise the parking brake will

not hold the transmission in any drive

position.

4.
Shift the selector lever through

all positions, and place the lever at P.

Do not turn off the engine during the

fluid level checks.

5.
Clean all dirt from the transmis-

sion fluid dipstick cap before remov-

ing the dipstick from the filler tube.

6. Pull the dipstick out of the tube,

wipe it clean, and push it all the way

back into the tube. Be sure it is prop-

erly seated.

7.
Pull the dipstick out of the tube

again, and check the fluid level. The

fluid level should be above the ADD

mark. If necessary, add enough fluid

to the transmission through the filler

tube to bring the level between the

ADD and FULL marks on the dip-

stick. Do not overfill the transmission.

Install the dipstick, making sure it is

fully seated in the tube.
8. Connect the vacuum brake re-

lease line if so equipped, and test it

for proper operation.

FLUID AERATION CHECK

A fluid level that is too high will

cause the fluid to become aerated:

Aerated fluid will cause low control

pressure, and the aerated fluid may be

forced out the vent.

Check the transmission fluid level.

Low fluid level can affect the opera-

tion of the transmission, and may in-

dicate fluid leaks that could cause

transmission damage.

TRANSMISSION FLUID

LEAKAGE CHECKS

Check the speedometer cable con-

nection at the transmission. Replace

the rubber seal if necessary.

Leakage at the oil pan gasket often

can be stopped by tightening the at-
