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

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.

Plate Installation

Prior to clutch plate installation,

the friction bonded plates must be

soaked in C6AZ-19570-C (ESW-

M2C-104-A) differential lubricant for

approximately 1/2 hour. In addition,

the differential lubricant must be lib-

erally applied to all components to

be assembled.

Place the clutch hub into posi-

tion in a soft-jawed vise.

2.
First, install a steel clutch plate

in the cavity of the differential case

opposite the ring gear and then a

bonded friction plate (Fig. 53). Any

tab on the steel plates can be inserted

into any cavity in the differential case,

however when the first steel plate is

inserted the others must be placed in

the same manner (Fig. 54) so the tabs

with slots line up. Install the remain-

6. With a suitable drift, install the

shaft lock pins. Make sure the pinion

and side gears move freely.

7.
Place the four pre-load springs in

the holes provided in the center block.

8. Position a pre-load plate over the

four springs, making sure the springs

are properly seated. The pre-load

plate straddles the center block over

bricant, for approximately 30 minutes

before installation.

12.
Place the clutch hub with the

clutch plates into the clutch ear cavi-

ties in the differential cover. Make

sure that the splines on the last fric-

ion plate are engaged on the hub.

13.
Obtain locally a 5/8 inch x

2 1/2 inch or 9/16 inch x 2 1/2

inch bolt, nut and two I 1/2 inch

outside diameter flat washers approx.

1/8 inch in thickness. These parts are

required to compress the clutch pack

in order to obtain the proper shim

selection.

Install a flat washer on the bolt,

and place the bolt through the clutch

hub.
Hold the bolt in position and

turn the cover over. Place a flat wash-

er on the bolt and then install the nut.

Be sure the washers are centered, and

torque the nut 10 to 15 ft-lbs (Fig.

observed between the shim tool and

the cover-to-case mating surface.

Using a feeler gauge, determine the

exact amount of clearance. Refer to

the shim pack thickness chart specifi-

cations which will indicate the correct

amount of shim(s) to subtract from

the 0.050 shim originally installed. In

order to correctly select the proper

shim(s), the shim template tool and

the chart must be used.

15.
After the proper shim selection

is determined, remove the bolt, nut

and flat washers. If it is necessary to

revise the shim thickness, remove the

clutch hub and clutch plates.

16.
Install the selected shim(s) in

the cover cavity, reinstall the compo-

nents as outlined in Steps 11 and 12.

17.
Install the four steel clutch ear

guides and side gear.

18.
Place both assemblies in a

press,
and press the two halves togeth-

er; then, insert the two Allen or Phil-

lips head screws, and tighten evenly

until tight. If a press is not available,

any two stock bolts and nuts may be

used opposite each other in the ring

gear retaining holes to compress both

halves.

19.
Install the ring gear and ring

gear bolts and washers. Tighten evenly

and alternately across the diameter of

the ring gear. Torque the bolts to

65-80 ft-lbs.

20.
Prior to installation of the tor-

que sensitive locking differential into a

vehicle, a bench torque check must be

made. Check the torque required to

rotate one side gear while the other is

held stationary (Fig. 56). The initial

break-away torque may exceed 250

ft-lbs.
The rotating torque required to

keep the side gear turning with new

clutch plates is 100 to 250 ft-lbs. With

re-used clutch plates, the minimum

torque required is 40 ft-lbs. (The tor-

que may fluctuate 10-40 ft-lbs.).
