DESCRIPTION

The automatic level control
is an

accessory item
on the
Ford, Mercury

and Meteor vehicles
(Fig. 1).
This
de-

vice
is a
supplement
to the
rear coil

spring suspension,
and
will automati-
cally maintain
the
rear standing height

of
the
vehicle
at an
approximate
con-

stant position compensating
for
vary-

ing loaded conditions.
The
system

consists
of a
vacuum operated
com-
pressor, control valve,
air
cylinders

and
the
connecting lines
and
fittings.

In
the
event
of
accidental
air
loss,
the

conventional coil springs will support

the vehicle.

3 IN-VEHICLE ADJUSTMENTS AND REPAIRS

REGULATOR ADJUSTMENT HEIGHT CONTROL VALVE

The regulator may be adjusted if

the regulator pressure is under 100 psi

with the reservoir pressure at a mini-

mum of 140 psi. If the regulated pres-

sure exceeds 130 psi, the regulator

must be replaced.

To adjust the regulator, remove the

boot and reposition the sleeve and re-

tainer deeper into the body of the re-

gulator, using a deep well socket (Fig.

4).
If the regulator pressure remains

under 100 psi, replace regulator.
SILICONE FLUID

REPLACEMENT

If the height control valve time

delay does not fall within specifica-

tion, the silicone fluid must be re-

placed. Then repeat the time delay

test. If delay is still not within specifi-

cations, replace the height control

valve.

1.
Remove control valve and clean
the exterior of the valve thoroughly.

2.
Position the valve with delay

plug on top. Remove delay plug and

drain silicone fluid from the chamber.

Remove the O-ring from the chamber

(Fig. 5), and discard the O-ring.

3.
Remove the cover plate retaining

ring, using snap ring pliers. Remove

the delay cover from the valve body.

Remove the O-ring from the chamber,

and discard the O-ring.

4.
Place a new O-ring over the

delay plug and install the plug. Tor-

que the plug to 20-30 in-lbs. .

5.
Pour silicone fluid into the delay

piston chamber until fluid level is 5/16

inch below the top edge of the body.

Add or remove fluid with an eye drop-

per until the proper fluid level is

reached.

6. Hold the control valve body in a

vise with the delay chamber elevated

slightly. Carefully operate the lever to

purge trapped air from the fluid.

7.
Place a new O-ring in the groove

around the delay piston bore. Install

The pattern taken during disassem-

bly should be helpful in judging if

gears can be re-used. Worn gears can-

not be rebuilt to correct a noisy condi-

tion. Gear scoring is the result of ex-

cessive shock loading or the use of an

incorrect lubricant. Scored gears can-

not be re-used.

Examine the teeth and thrust surfa-

ces of the differential gears. Wear on

the hub of the differential gear can

cause a chucking noise known as

chuckle when the vehicle is driven at

low speeds. Wear of splines, thrust

surfaces, or thrust washers, can con-

tribute to excessive drive line back-

lash.

BEARING CUPS AND

CONE AND ROLLER

ASSEMBLIES

Check bearing cups for rings,

scores, galling, or excessively worn

wear patterns. Pinion cups must be

solidly seated. Check by attempting to

insert a 0.0015-inch feeler between

these cups and the bottoms of their

bores.

When operated in the cups, cone

and roller assemblies must turn with-

out roughness. Examine the roller

ends for wear. Step-wear on the roller

ends indicates the bearings were not

preloaded properly, or the rollers were

slightly misaligned.

If inspection reveals either a defec-

tive cup or a defective cone and roller

assembly, both parts should be re-

placed to avoid early failure.

DIFFERENTIAL BEARING

ADJUSTING NUTS

Temporarily install the bearing caps

and test the fit of the adjusting nuts in

their threads. The nuts should turn

easily when the caps are tightened to

25 ft-lbs. The faces of the nuts that

contact the bearing cups must be

smooth and square. Replace the nuts

or examine the threads in the carrier
if their fit is not proper. Be sure that

the bearing caps and adjusting nuts

are on the side they were machined to

fit. Observe the punch marks and

scribe marks made during disassem-

bly.

U-JOINT FLANGE

Be sure that the eai» of the flange

have not been damaged in removing

the drive shaft or in removing the

flange from the axle. The end of the

flange that contacts the front pinion

bearing inner race as well as the flat

surface of the pinion nut counterbore

must be smooth. Polish these surfaces

if necessary. Roughness aggravates

backlash noises and causes wear of

the flange and pinion nut with a resul-

tant loss in pinion bearing preload.

PINION RETAINER

Be sure that the pinion bearing cups

are seated. Remove any chips or burrs

from the mounting flange. Clean the

groove for the O-ring seal and all lu-

bricant passages. If the cups were re-

moved, examine the bores carefully.

Any nicks or burrs in these bores

must be removed to permit proper

seating of the cups.

CARRIER HOUSING

Make sure that the differential

bearing bores are smooth and the

threads are not damaged. Remove any

nicks or burrs from the mounting sur-

faces of the carrier housing.

DIFFERENTIAL CASE

Make sure that the hubs where the

bearings mount are smooth. Carefully

examine the differential case bearing

shoulders, which may have been dam-

aged when the bearings were removed.

The bearing assemblies will fail if they

do not seat firmly against the shoul-

ders.
Check the fit (free rotation) of
the differential side gears in their

counterbores. Be sure that the mating

surfaces of the two parts of the case

are smooth and free from nicks or

burrs.

LIMITED SLIP AND

TRACTION-LOK

DIFFERENTIAL PARTS

Inspect the clutch plates for uneven

or extreme wear. The dog-eared clutch

plates must be free from burrs, nicks

or scratches which could cause excess-

ive or erratic wear to the bonding ma-

terial of the internally splined clutch

plates.
The internally splined clutch

plates should be inspected for condi-

tion of the bond, bonding material,

and wear. Replace the bonded plates

if their thickness is less than 0.085

inch or if the bonded material is

scored or badly worn. Inspect the

bonded plate internal teeth for wear.

Replace them, if excessive wear is evi-

dent. Bonded plates should be re-

placed as a set only

Examine all thrust surfaces and

hubs for wear. Abnormal wear on

these surfaces can contribute to a

noisy axle.

Inspect the Belleville spring (limited

slip) for proper free height of 1/4

inch.

LUBRICANT LEVEL

The lubricant level should be

checked every 6000 miles with the ve-

hicle in normal curb attitude. The lu-

bricant level should be at the lower

edge of the filler plug hole located in

either the carrier casting or housing

cover. It is unnecessary to periodically

drain the axle lubricant. The factory

fill should remain in the housing for

the life of the vehicle, except when re-

pairs are made. The specified lubri-

cant should be installed when the axle

is overhauled.procarmanuals.com
