(2) Install Dial Indicator (Fig. 31). Position the
plunger against the drive side of a ring gear tooth. Measure the backlash at 4 positions (90 degrees apart) around the ring gear. Locate and mark the
area of minimum backlash.
(3) Rotate the ring gear to the position of the least
backlash. Mark the gear so that all future backlash
measurements will be taken with the same gear
teeth meshed.
(4) Loosen the right-side, tighten the left-side
threaded adjuster. Obtain backlash of 0.003 to 0.004
inch (0.076 to 0.102 mm) with each adjuster tight­
ened to 14 N-m (10 ft. lbs.) torque. Seat the bearing
cups with the procedure described above.
(5) Tighten the differential bearing cap bolts;
• 8 3/8 axles to 95 N-m (70 ft. lbs.) torque
• 9 1/4 axles to 136 N-m (100 ft. lbs.) torque
(6) Use Wrench C-4164 to tighten the right-side
threaded adjuster to 102 N-m (75 ft. lbs.) torque. Seat the bearing cups with the procedure described above. •

Measurement Continue to tighten the right-side adjuster and seat
bearing cups until the torque remains constant at 102 N-m (75 ft. lbs.)
(7) Measure the ring gear backlash. The range of
backlash is 0.006 to 0.008 inch (0.15 to 0.203 mm).
Continue increasing the torque at the right-side
threaded adjuster until the specified backlash is ob­ tained.
The left-side threaded adjuster torque should
have approximately 102 N-m (75 ft. lbs.) torque. If the torque is considerably less, the complete adjustment procedure must be repeated. (8) Tighten the left-side threaded adjuster until
102 N-m (75 ft. lbs.) torque is indicated. Seat the
bearing rollers with the procedure described above. Do this until the torque remains constant. (9) Install the threaded adjuster locks . Ensure the
lock finger is engaged with the adjuster hole.
Tighten the lock screws to 10 N-m (90 in. lbs.) torque.
SIDE
GEAR CLEARANCE
MEASUREMENT
AND

ADJUSTMENT

When measuring side gear clearance, check each
gear independently. If it necessary to replace a side
gear, replace both gears as a matched set.
(1) Install the axle shafts and C-clip locks and pin­
ion mate shaft. If necessary, refer to the installation
located within this group. (2) Measure each side gear clearance. Insert a
matched pair of feeler gauge blades between the gear
and differential housing on opposite sides of the hub (Fig. 32).
(3) If side gear clearances is no more than 0,005
inch. Determine if the shaft is contacting the pinion
gear mate shaft. Do not remove the feeler gauges,
inspect the axle shaft with the feeler gauge in­ serted behind the side gear. If the end of the axle
shaft is not contacting the pinion gear mate shaft,
the side gear clearance is acceptable.
• Insufficient adjuster torque will not support the
ring gear correctly and can cause excessive differen­
tial case free-play and ring gear noise
The differential bearing cups will not always
immediately follow the threaded adjusters as they are moved during adjustment. Ensure accu­
rate bearing cup responses to the adjustments. Maintain the gear teeth engaged (meshed) as
marked. The bearings must be seated by rapidly
rotating the pinion gear a half turn back and forth. Do this five to ten times each time the
threaded adjusters are adjusted.
(1) Use Wrench C-4164 to adjust each threaded ad­
juster inward (Fig. 30). Adjust until the differential bearing free-play is eliminated. Allow some ring gear
backlash (approximately 0.01 inch/0.25 mm) between
the ring and pinion gear. Seat the bearing cups with
the procedure described above.

In some cases,
the end of the
axle shaft will move
and contact
the
mate shaft when
the

is

inserted.
The
C-clip lock
is
preventing
the
side gear
from sliding
on the
axle shaft.
(5)
If
there
is no
side gear clearance, remove
the

C-clip lock from
the
axle shaft.
Use a
micrometer
to
measure
the
thrust washer thickness. Record
the

thickness
and
re-install
the
thrust washer. Assemble
the differential case without
the
C-clip lock installed and re-measure
the
side gear clearance.
(6) Compare both clearance measurements.
If the

difference
is
less than
0,012
inch (0.305
mm), add
clearance recorded when
the
C-clip lock
was
installed
to thrust washer thickness measured.
The sum
will determine
the
required thickness
of the
replacement
thrust washer.
(7)
If
clearance
is 0.012
inch (0.305
mm) or

greater, both side gears must
be
replaced (matched set)
and the
clearance measurements repeated.
(8)
If
clearance (above) continues
to be 0.012

ANALYSIS
The ring gear teeth contact patterns will show
if

the pinion gear depth shim(s) have
the
correct thick­
ness.
It
will also show
if the
ring gear backlash
has

been adjusted correctly.
The
backlash must
be
main­ tained within
the
specified limits until
the
correct
teeth contact patterns
are
obtained.
• Excessive backlash
is
corrected
by
moving
the
ring gear teeth closer
to the
pinion gear teeth
• Insufficient backlash
is
corrected
by
moving
the

ring gear away from
the
pinion gear
(1) Apply yellow ferrous (iron) oxide compound
to

both drive

coast sides
of
ring gear teeth. (2) Rotate
the
ring gear
one
complete revolution
in

both directions.
(3) Note patterns
in
compound. Refer
to (Fig. 34)

for interpretation
of
contact patterns
and
adjust
ac­
cordingly.
(4) Install
the
axle shafts. Refer
to
Axle Shaft

stallation within this group. (5) Install
the
housing cover. Refill
the
differential
with lubricant. Refer
to

Sure-Grip
Differential
Components
The action
of a
standard differential will allow
the

rear wheels
to
rotate
at
different speeds when
the ve­

hicle
is
turning. This differential will divide
the en­
gine torque equally between them. This
is a
desirable
and
normal function
of a
differential.
A

Sure-Grip differential transfers additional engine
torque
to the
rear wheel that
has the
better traction surface.
The
Sure-Grip differential allows
the
driving
wheel with better traction
to
develop more driving
torque than
the
other wheel.
The
Sure-Grip
is not a
locking type differential.
IDENTIFICATION Raise both rear wheels
off the
surface
and
rotate
them.
If
both rear wheels rotate
in the
same direc­
tion,
the
vehicle
is
equipped with
a
Sure-Grip differ­ ential. Another method
of
identification
is by

removing
the
housing cover fill hole plug. Examine (with
a
flashlight)
the
differential case components
through
the
lubricant fill hole.
SERVICE INFORMATION When Sure-Grip differential service
is
necessary,
both rear wheels must
be
raised
off the
surface
so
they
are
free
to
rotate.
A Sure-Grip differential case
is not
repairable.
If defective,
it
must
be
replaced
as a
complete
unit only.
Do not
attempt
to
disassemble
and re­

pair
the
case components.
Follow
the
same procedure outlined under Stan­
dard Differential
for
Removal
and
Installation.
DIFFERENTIAL TEST

CAUTION:
Whenever
a
rear axle
is
being
serviced,
RAISE
BOTH
REAR
WHEELS
off the
surface.
A Sure-Grip differential
can be
tested without
re­

moving
the
differential case from
the
housing.
(1) Position
the
vehicle
on a
hoist with
the
ignition

OFF.
Put the
transmission selector lever
in
PARK
(automatic transmission)
or in
first gear (manual
transmission).
(2) Attempt
to
manually rotate each rear wheel.
(3)
If
difficult
to
manually rotate either wheel,
the

Sure-Grip differential
is
functioning normally.
If

easy,
the
differential
is not
functioning normally
and
should
be
replaced.
A Sure-Grip differential case
is not
repairable.
If defective,
it
must
be
replaced
as a
complete
unit only.
Do not
attempt
to
disassemble
and re­

pair
the
case components.
DIFFERENTIAL NOISE Noise complaints involving
a
Sure-Grip should
be

evaluated
to
determine
the
source
of the
noise.
If a

noise occurs while
the
vehicle
is
turning,
the
proba­
ble cause
is
incorrect
or
insufficient gear lubricant. The drain
and
clean procedure should
be
used
for

possible elimination
of the
noise before replacing
the
differential.

LUBRICATION

Multi-Purpose Gear Lubricant, as defined by MIL-
L-2105-B (API GL-5) should be used in all axles.
MOPAR Hypoid Lubricant is recommended or equiv­ alent. In Sure-Grip differentials 4 ounces of MOPAR Hy­
poid Gear Lubricant Additive must be added with each re-fill.
It is recommended the vehicle be driven through 10
to 12 slow, figure-eight turns. This ensures the lubri­ cant is thoroughly pumped through the Sure-Grip
differential clutches.

GENERAL
INFORMATION

The housing (Fig. 1) consists of an iron center cast­
ing with axle shaft tubes extending from either side.
The tubes are pressed in to form a one-piece axle housing. The integral type housing, hypoid gear design has
the centerline of the pinion set below the centerline of the ring gear. The axles are equipped with full-floating axle

shafts,
meaning that loads are supported by the axle
housing tubes. The full-float axle shafts are retained
by bolts attached to the hub. The hub rides on two
bearings at the outboard end of the axle tube. The axle shafts can be removed without disturbing or re­
moving the wheel bearings. The wheel bearings are
opposed tapered roller bearings that are part of the
hub/drum assembly.

The removable, stamped steel cover provides a
means for inspection and service without removing
the complete axle from the vehicle.
A small, stamped metal axle gear ratio identifica­
tion tag is attached to the housing cover via one of
the cover bolts. This tag also identifies the number of
ring and pinion teeth.
The differential case is a one-piece design. The
dif­

ferential pinion mate shaft is retained with a roll
pin. Model 70 axles with the optional Powr-Lok use a
two piece differential case. Differential bearing pre­ load and ring gear backlash are adjusted by the use
of shims located between the differential bearing
cones and case.

bearings for wear. Replace as necessary.
CLEANING AND INSPECTION (1) Thoroughly clean both wheel bearings and in­
terior of the hub. Remove all of the residual lubri­ cant. (2) To clean the bearings:
• Soak them in an appropriate cleaning solvent
• Strike the flat of each bearing against a hardwood
block several times • Flush bearing between strikes
• Repeat the procedure above until each bearing is clean
• Dry the bearings with compressed air but do not
spin them (3) After cleaning, apply engine oil to each bear­
ing. (4) Rotate each bearing slowly while applying
downward force. Examine the rollers for pitting and
roughness. Replace worn or otherwise defective bear­
ings.
If a bearing has pitted and/or rough surfaced
rollers, replace both the bearing and bearing cup. (5) If reusable, remove the engine oil from each
bearing. Pack each bearing with multi-purpose
NLGI, grade 2, EP-type lubricant. Ensure that lubricant is forced into all the cav­
ities between the bearing cage and rollers.
INSTALLATION (1) If a bearing and cup must be replaced, remove
the cup from the hub bore. Use a brass drift or an appropriate removal tool to tap out the cup. (2) Install the replacement bearing cup(s) with an
appropriate installation tool.
(3) Apply lubricant to surface area of the hub bore.
Install the inner wheel bearing in the hub. Install a
replacement bearing seal with an appropriate seal installation tool. (4) Inspect the bearing and seal contact surfaces on
the axle for burrs and/or roughness.
(5) Remove all the rough contact surfaces from the

axle.
Apply a coating of multi-purpose NLGI, grade

2,
EP-type lubricant to the axle.

CAUTION:
