Rear Axles — Integral Carrier Type

04-03-04

1.
Remove the wheel cover, wheel

and tire from the brake drum.

2.
Remove the Tinnerman nuts that

secure the brake drum to the axle

housing flange, and then remove the

drum from the 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. 2). The brake backing

plate must, not be dislodged. Install

one nut to hold the plate in place after

the axle shaft is removed.

4.
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. 3). It will

then slide off easily.

5.
Remove the bearing from the

axle shaft with the tool shown in Fig.

4 or 5. If the push-puller operation

shown in Fig. 5 is used, be sure that

the puller arms contact the flat sur-

face of the axle shaft flange rather

than the bolt heads. Also with this

method, be careful not to damage or

burr the oil seal journal as the bearing

breaks loose.

6. Whenever a rear axle shaft is re-

placed the oil seal must be replaced.

Remove the seal with the tools shown

in Fig. 8. Soak new oil seals in SAE

10 oil for 1/2 hour before installing.

7.
Inspect the machined surfaces 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 damage.

Carefully remove any burrs or rough

spots.
Replace worn or damaged

parts.

8. Lightly coat wheel bearing bores

with axle lubricant.

9. Place the retainer plate on the

axle shaft, and press the new wheel

bearing on the shaft with the tool

shown in Fig. 4 or 5. The bearing

should seat firmly against the shaft

shoulder. Do not attempt to press on

both the bearing and the inner retain-

er ring at the same time.

10.
Using the bearing installation

tool, press the bearing inner retainer

ring on the shaft until the retainer

seats firmly against the bearing.

11.
Wipe all lubricant from the in-

side of the axle housing in the area of

the oil seal before installing the new

seal.

12.
Wipe a small amount of oil res-

istant sealer on the outer edge of the

seal before it is installed. Do not put

sealer on the sealing lip.

13.
Rear wheel oil seals with syn-
thetic sealing elements have been in-

corporated in production. However,

only leather seals will be used as re-

placements for the synthetic sealing

element seals. Install the new oil seal

with the tools shown in Fig. 8. Instal-

lation without use of the proper tool

will distort the seal and cause leakage.

Be sure the new seal has been soaked

in SAE 10 oil for 1/2 hour.

14.
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.

15.
Install the bearing retainer plate

on the mounting bolts at the axle

housing, and install the attaching nuts.

Torque the nuts to specifications.

16.
Install the brake drum and the

drum retaining nuts.

17.
Install the wheel and tire on the

drum, and install the wheel cover.

REMOVAL AND REPLACEMENT

OF DRIVE PINION OIL SEAL

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvent.

Replacement of the pinion oil seal

involves removal and installation of

only the pinion shaft nut and the uni-

versal joint flange. However, this op-

eration disturbs the pinion bearing
preload, and this preload must be

carefully reset when assembling.

1.
Raise the vehicle and install safe-

ty stands. Remove the 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. 14). 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

tool in the transmission extension

housing to prevent transmission leak-

age.
Refer to the transmission group

for the appropriate tool.

3.
Install an in-lb torque wrench on

the pinion nut Fig. 6. Record the tor-

que required to maintain rotation of

the pinion shaft through several revo-

lutions. \

4.
While holding the flange with the

tool shown in Fig. 9, remove the inte-

gral pinion nut and washer.

5.
Clean the pinion bearing retainer

around the oil seal. Place a drain pan

under the seal, or raise the front of

the vehicle higher than the rear.

For example, on a C4 transmission,

if the pressure at 10 inches of vacuum

was 120 psi and the pressure at 1.0

inch of vacuum was 170 psi, and up-

shifts and downshifts were harsh, a di-

aphragm adjustment to reduce the di-

aphragm assembly spring force would

be required.

If the pressure readings are low, an

adjustment to increase diaphragm

spring force is required.

To increase control pressure, turn

the adjusting screw in clockwise to re-

duce control pressure, back the adjust-

ing screw out by turning it counte-

rclockwise. One complete turn of the

adjusting screw (360 degrees) will

change idle line control pressure ap-

proximately 2-3 psi. After the adjust-

ment is made, install the vacuum line

and make all the pressure checks as

outlined in the Specification Section.

The diaphragm should not be ad-

justed to provide pressure below the

ranges shown in the Specification Sec-

tion in order to change shift feel. To

do so could result in soft or slipping

shift points and damage to the trans-

mission.

ALTITUDE

COMPENSATING TYPE

The altitude—compensating di-

aphragm is provided with an adjust-

ment screw located in the vacuum

connecting tube (Fig. 15). The adjus-

table feature allows control and TV

pressures to be adjusted (within limits)

to correct soft or harsh shift feel.

Control and TV pressures are in-

creased or decreased by turning the

adjusting screw.

Before replacing or adjusting the di-

aphragm, it must first be determined

that the pressure or vacuum is actual-

ly out of specification and that the

cause of the problem is not due to

other items within the transmission or

vacuum connecting lines.

If the tests outlined in the Specifi-
cation Section have been performed

and pressures are within specification

but shift feel is unsatisfactory, or if

the pressure is too high or too low at

10 inches of vacuum, the vacuum di-

aphragm may be adjusted to improve

the shift feel.

If shifts are excessively harsh, the

diaphragm should be adjusted to re-

duce control pressure by backing off

the adjusting screw (counterclock-

wise).
If shift quality is extremely soft,

control pressure should be increased

by turning the adjusting screw inward

(clockwise).

To adjust the vacuum diaphragm to

compensate for harsh shift quality,

first check control pressure in D, 2

and 1 at 10 inches manifold vacuum

and note the pressure reading ob-

tained. Remove the T-fitting from the

vacuum hose and back off the adjust-

ing screw (counterclockwise) by one

full turn. Each full turn will reduce

control pressure by approximately 2

1/2 psi at 10 inches of vacuum. Test

the vehicle for shift feel. If shift quali-

ty is still harsh, a further adjustment

should be made to reduce control

pressure. However, control pressure

should not be reduced below the speci-

fication shown for 10 inches of vacu-

um. If control pressure has been re-

duced to the low limit and shift feel is

still excessively harsh, the clutches and

band should be checked for correct

operation.

To adjust the vacuum diaphragm to

compensate for extremely soft shifts,

record the control pressure reading at

10 inches of vacuum in D, 2 and 1,

then make an initial adjustment of

one full turn inward (clockwise). Test

the vehicle for shift feel and again ad-

just the diaphragm, if necessary. Con-

trol pressure at 10 inches of vacuum

must not exceed the high limit shown

in the Specification Section.

When the necessary adjustments

have been completed and shift feel is

satisfactory, repeat all the tests out-

NEUTRAL START SWITCH

ADJUSTMENT AND

REPLACEMENT—COLUMN SHIFT

There are two types of column-

mounted neutral start switches: A and

B.
Type A switch has a parking brake

brake-release vacuum valve. Type B

switches do not have a vacuum valve.

The switches differ in appearance but

not in operation. Both switches are

actuated by a removable steel lever,

which is installed in the shifter tube

within the steering column assembly.

The following procedures outline the

steps necessary to correctly adjust and

replace the neutral start switch.

SWITCH ADJUSTMENT

Neutral Position

1.
With the selector lever held light-

ly against the neutral stop, attempt to

start the engine. If the engine starts

while holding the lever but does not

start when the lever is released, the

shift linkage should be adjusted. If the

engine does not start in either condi-

tion, adjust the switch.

2.
To adjust the switch in neutral,

place the transmission selector lever

against the stop of the neutral detent

position.

3.
Loosen the two retaining screws

that locate the switch on the steering

column (Fig. 16).

4.
With the selector lever against

the neutral stop, rotate the switch

until a start in the neutral position is

obtained. Then, tighten the switch at-

taching screws to 20 in-lbs torque.

5.
With the switch properly adjust-

ed in neutral, place the selector lever

in the 1 position and push the park

reset button (Fig. 16) to the left

(counterclockwise) until it stops. The

park reset must be performed when-

ever the switch has been adjusted.

Park Position

1.
Place the selector lever in the

park position, release the lever and at-

tempt to start. If the engine does not

start, reset the park adjustment.procarmanuals.com

07-01-10
General Transmission Service

07-01-10

2.
To adjust the switch for the park

position, place the transmission selec-

tor lever in 1 and push the park reset

button (Fig. 16) to the left (counter-

clockwise) until it stops.

3.
Check the operation of the

switch in each selector lever position.

The starter should engage in only the

neutral and park positions. Be sure to

perform
the
park reset
if for any rea-

son
the
neutral switch
is
adjusted.

If,
after performing
the
switch
ad-

justments,
the
starter still will
not en-

gage
in the
neutral
or
park positions,

replace
the
switch. Never replace
the

neutral switch until
the
switch adjust-

ments have been made.

SWITCH REPLACEMENT

1.
Disconnect the neutral start

switch wires at the plug connector.

2.
Disconnect the vacuum hoses, if

so equipped.

3.
Remove the two screws securing

the neutral start switch to the steering

column and lift the switch from the

column.

Check the column to be sure the

metal switch actuator is secure to the

shift tube and that it is seated as far

forward against the shift tube bearing

as is possible. Also check for a broken

or damaged actuator. If it is broken

or damaged, replace it as shown in

Figure 17.

4.
Before installing a new switch to

the column, check to see that the red

neutral position gauge inserted in the

neutral pinning hole. If the pin is

missing, align the two holes at the

neutral pinning hole on top of the

switch and install a No. 43 drill or

0.092-0.093 inch gauge pin.
