DESCRIPTION

The roller-type hydraulic pump,

driven by the crankshaft, draws auto-

matic transmission fluid down the res-

ervoir and provides fluid pressure for

the system. Steering gear lubrication
is also provided by the same fluid

from the reservoir. Within the pump

itself is a flow-control and pressure-

relief valve which governs the pres-
sures within the steering system ac-

cording to the varying conditions of

operation. After fluid has passed from

the gear, it returns to the reservoir.

1.
Raise the vehicle until the wheel

and tire clear the floor.

2.
Pry off the wheel cover and re-

move the grease cap (Fig. 2) from the

hub.

3.
Wipe the excess grease from the

end of the spindle, and remove the ad-

justing nut cotter pin and nut lock.

4.
Loosen the bearing adjusting nut

three turns. Then, rock the wheel,

hub,
and rotor assembly in and out

several times to push the shoe and lin-

ings away from the rotor.

5.
While rotating the wheel, hub,

and rotor assembly, torque the adjust-

ing nut to 17-25 ft-lbs to seat the

bearings (Fig. 4).

6. Back the adjusting nut off one

half turn. Then, retighten the adjust-

ing nut to 10-15 in-lbs with a torque

wrench or finger tight.

roughly or noisily, clean or replace the

bearings and cups as required.

10.
Before driving the vehicle,
pump the brake pedal several times to

obtain normal brake lining to rotor

clearance and restore normal brake

pedal travel.

BALANCING LIFE

GUARD TIRE

Tires fitted with the Life Guard

Safety Spare are balanced in the same

manner as conventional tires. If an ex-

cessive out of balance condition exists

the following procedure can be used to

correct the condition:

1.
Remove the core housing and de-

flate both air chambers.

2.
Install the core housing.

3.
Unseat the beads of tire with the

bead breakers away from the valve

stem as shown in Fig. 5.

F 1383

FIG. 5—Breaking Top Bead of

Tire From Wheel Rim
4.
Rotate tire casing 90 degrees on

the wheel rim.

5.
Rotate the tire casing back and

forth on the rim to center the valve.

6. Inflate both chambers of the tire

following steps 13 through 15 of the

Tire Installation procedure.

7.
Balance the tire in the normal

manner.

CORRECTING VIBRATION

AND SHAKE-

LIFE GUARD TIRE

The condition of excessive vibration

and shake is generally the result of an

incorrect pressure relationship between

the inner and outer air chambers that

may cause the life guard to shift posi-

tion within the tire. The following

procedure should be used to correct

vibration and shake conditions:

1.
Check pressure of the inner and

outer air chambers on all four tires.

2.
If the inner chamber has at least

five psi more pressure than the outer

chamber the pressures should be ad-

justed and the tires rebalanced if nec-

essary.

3.
If the pressures of the inner and

outer air chambers are equal the Air

Container is leaking. To repair the

leaking air container the recommend-

ed procedures for the removal, repair

of air container, mounting, and bal-

ancing should be followed.

REMOVAL AND INSTALLATION

HOISTING INSTRUCTIONS

Damage to steering linkage compo-

nents and front suspension struts may

occur if care is not exercised when po-

sitioning the hoist adapters of 2 post

hoists prior to lifting the vehicle.

If a 2 post hoist is used to lift the

vehicle, place the adapters under the

lower arms or the No. 1 crossmember.

Do not allow the adapters to contact

the steering linkage. If the adapters

are placed under the crossmember, a

piece of wood (2x4x16 inches) should

be placed on the hoist channel be-

tween the adapters. This will prevent

the adapters from damaging the front

suspension struts.

If the tooth pattern indicates a change

in shim thickness, follow the proce-

dure under Pinion Location.

REMOVABLE CARRIER

TYPE AXLE

The shim location for the removable

carrier type axle is between the pinion

retainer and the carrier (Fig. 13).

When adjusting this type carrier re-

ducing shim thickness will move the

pinion toward the ring gear; increas-

ing shim thickness will move the pi-

nion away from the ring gear (Fig.

13).

8. If the runout is still excessive, re-

place the companion flange and check

the runout. If necessary, rotate the

new flange on the pinion shaft until an

acceptable runout is obtained.

If excessive runout is still evident

after replacement of the companion

flange, it will be necessary to replace

the ring and pinion gear, and repeat

the above checks until runout is within

specifications.

PINION AND RING GEAR

TOOTH CONTACT

ADJUSTMENT

Two separate adjustments affect pin-

ion and ring gear tooth contact.

They are pinion location and backlash

(Figs.
12 and 13).

Individual differences in matching

the differential housing and the gear

set require the use of shims to locate

the pinion for correct contact with the

ring gear.

When adjusting either type axle,

shim thickness should be increased or

reduced only as indicated by the tooth

pattern check described in the fore-

going Section 1.

a change in backlash only, follow the

Tooth Contact Adjustment—

Removable Carrier Axles
The shim location for the integral

carrier type axle, is between the pi-

nion gear and the pinion rear bearing

cone (Fig. 12). When adjusting this

type axle, increasing shim thickness

moves the pinion toward the ring

gear; reducing shim thickness moves

the pinion away from the ring gear

(Fig. 12).

BACKLASH AND DIFFERENTIAL

BEARING PRELOAD

ADJUSTMENTS (ALL AXLES)

On a Light-Duty (WER) Axle, it is

necessary to remove the rear axle

shafts prior to performing the adjust-

ment procedures. Refer to Rear Axle

Shaft Wheel Bearing and Oil Seal Re-

placement—Light-Duty (WER), Axle,

Part 4-4, Section 2.

To secure a more uniform control

of differential side bearing preload in

service repairs, a dial indicator set-up

such as shown in Fig. 12 is used.

In both types of axle (Fig. 11 and

12),
the ring gear is moved away from

or toward the pinion as described in

the following procedure.

1.
Remove the adjusting nut locks,

loosen the differential bearing cap

bolts,
then torque the bolts to 15 ft-lbs

on integral carrier type axle; 20 ft-lbs

on removable carrier type axles before

making adjustments.

2.
The left adjusting nut is on the

ring gear side of the carrier. The right

nut is on the pinion side. Loosen the

right nut until it is away from the cup.

Tighten the left nut until the ring gear

is just forced into the pinion with

0.000 backlash then rotate the pinion

several revolutions to be sure no bind-

ing is evident. (Recheck the right nutprocarmanuals.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.

reading established in step 3.

16.
After original preload has been

reached, tighten the pinion nut slowly,

until an additional preload of 8 to 14

in-lb over the original reading is

reached. The preload should not ex-

ceed 8 to 14 in-lb over the original

reading, or bearing failure may result.

Under no circumstances should the pi-

nion nut be backed off to lessen pre-

load. If this is done, a new pinion

bearing spacer must be installed. In

addition, the U-joint flange must

never be hammered on, or pneumatic

tools used.
