• Depth shims are available in O.OOl-ineh incre­
ments from 0.020 inch to 0.038 inch. (8) Note the etched number on the face of the drive
pinion gear (e.g., -0, -1, -2, +1, +2, etc.). The num­
bers represent thousands-of-an-inch deviation from
the standard. If the number is - (negative), add that
value to the required thickness of the depth shim(s).
If the number is + (positive), subtract that value
from the thickness of the depth shim(s). If the num­
ber is 0, no change is necessary.
(9) Remove the tools from the differential housing.
(10) Remove the rear bearing cup from housing

• Original Bearings — 1 to 3 N*m (10 to 20 in. lbs.) • New Bearings — 2 to 5 N»m (20 to 40 in. lbs.) If the preload torque is not within the specified tol­
erance, correct the shim thickness accordingly (Fig.

GENERAL INFORMATION
Axle bearing problem conditions
are
usually caused
by: • Insufficient
or
incorrect lubricant
• Foreign matter/water contamination
• Incorrect bearing preload torque adjustment When serviced,
the
bearings must
be
cleaned thor­
oughly. They should
be
dried with lint-free shop tow­

els.
Never
dry
bearings with compressed
air.

This will overheat them
and
brinell
the
bearing surfaces. This will result
in
noisy operation after
repair. Axle gear problem conditions
are
usually
the
result

of:

• Insufficient lubrication
• Incorrect
or
contaminated lubricant
• Overloading (excessive engine torque)
• Incorrect clearance
or
backlash adjustment Insufficient lubrication
is
usually
the
result
of a

housing cover leak.
It can
also
be
from worn axle shaft
or
pinion gear seals. Check
for
cracks
or
porous
areas
in the
housing
or
tubes.
Using
the
wrong lubricant will cause overheating
and gear failure. Gear tooth cracking
and
bearing
spalling
are
indicators
of
this.
Axle component breakage
is
most often
the
result

of:

• Severe overloading
• Insufficient lubricant
• Incorrect lubricant • Improperly tightened components
Common causes
of
overloading
is
from full-throttle
acceleration. Overloading occurs when towing
heavier than normal loads. Component breakage
can
occur when
the
wheels
are
spun excessively. Insuffi­
cient
or
incorrect lubricants contribute
to
breakage
through overheating. Loose differential components can also cause breakage. Incorrect bearing preload
or
gear backlash will
not

result
in
component breakage. Mis-adjustment will
produce enough noise
to
cause service repair before
a

AND

• level. Where axle bearing damage is slight, the noise
is usually not noticeable at speeds above 30 mph.

LOW SPEED KNOCK
Low speed knock is generally caused by a worn
U-joint or by worn side-gear thrust washers. A worn
pinion gear shaft bore will also cause low speed knock.

VIBRATION
Vibration at the rear of the vehicle is usually
caused by a:
• Damaged drive shaft
• Missing drive shaft balance weight
• Worn, out-of-balance wheel and tires
• Loose wheel lug nuts
• Worn U-joint • Loose spring U-bolts
• Loose/broken rear springs or shackles
• Damaged axle shaft bearings
• Loose pinion gear nut
• Excessive pinion yoke run out
• Bent axle shaft Check for loose or damaged front-end components
or engine/transmission mounts. These components
can contribute to what appears to be a rear-end vi­
bration. Do not overlook engine accessories, brackets and drive belts. All driveline components should be examined be­
fore starting any repair. Refer to Group 22, Wheels and Tires for additional
information.

DRIVELINE SNAP
A snap or clunk noise when the vehicle is shifted
into gear (or the clutch engaged), can be caused by: • High engine idle speed
• Loose engine/transmission/transfer case mounts

9
Worn U-joints
• Loose spring shackles or U-bolts
• Loose pinion gear nut and yoke
• Excessive ring gear backlash
• Excessive differential side gear-to-case clearance A worn bushing in the transmission extension
housing can also cause noise. The source of a snap or a clunk noise can be deter­
mined with the assistance of a helper. Raise the ve­
hicle on a hoist with the wheels free to rotate. Instruct the helper to shift the transmission into gear. Listen for the noise, a mechanics stethoscope is
helpful in isolating the source of a noise.

LIMITED
SLIP DIFFERENTIAL
Under normal traction conditions, engine torque is
divided evenly. With low-traction surfaces, engine
torque is transferred to the wheel with the most tire
traction. When diagnosing a limited-slip differential
problem condition, the wheel with the least traction can continue spinning. The most common problem is a chatter noise when
turning corners. Check for incorrect or contaminated lubricant. Replace the gear lubricant if necessary.
• With Sure-Grip differentials add a container of
MOPAR® Hypoid Gear Additive This will correct the condition in most instances. If
the chatter persists, clutch damage could have oc­ curred. After changing the lubricant, drive the vehicle and
make 10 to 12 slow, figure-eight turns. This maneu­
ver will pump lubricant through the clutches.

INFORMATION
The 8 3/8 and 9 1/4 axle (Fig. 1) housing consist of
a cast iron center section. They also have two steel
axle shaft tubes that are pressed into and welded to
the differential housing. The removable, stamped steel cover provides a
means for inspection and service without removing
the complete axle from the vehicle.

LUBRICANT
Multi-purpose, hypoid gear lubricant should be
used for 8 3/8 and 9 1/4 axles. The lubricant should
have MIL-L-2105C and API GL 5 quality specifica­

tions.
MOPAR® Hypoid Gear Lubricant conforms to
both of these specifications.
Refer to Group 0, Lubrication and Maintenance for
additional information.

CAUTION:
If a
rear axle
is
submerged
in
water,
the

axle lubricant must
be
replaced immediately.
DRAIN
AND
REFILL
(1) Drive the vehicle until the gear lubricant
reaches normal operating temperature.
(2) Raise and support the vehicle.
(3) Remove the lubricant fill hole plug from the
differential housing cover.
(4) Remove the differential housing cover. Allow
the original lubricant to completely drain from the
housing and axle shaft tubes. (5) With standard differential, clean the differen­
tial and the housing cavity with a flushing oil (or light engine oil). This will remove the residual lubri­
cant and foreign matter.Do not use water, steam,
kerosene or gasoline for flushing.

CAUTION:
DO NOT

Sure-Grip

ing

cloths.
(6)
Scrape the residual sealant from the housing
and cover mating surfaces. Clean the mating sur­
faces with mineral spirits. Apply a bead of MOPAR® Silicone Rubber Sealant on the housing cover (Fig.

2).
Allow the sealant to cure for a few minutes.

CAUTION:
Overfilling
the

can
result
in

SERVICE
CAUTION:
When rear axle service
is
necessary, both rear wheels must
be
raised
off the
surface
so

that
they
are
free
to
rotate.
Be
cautious when
the

tires
are
being rotated
by the
engine
or by
other
means.

CAUTION:
If
equipped
with
a
Sure-Grip
differential,

do
not
rotate
either
axle shaft unless both
are
prop­

erly
in-place. Rotation
of one
axle shaft without
the
other being installed
can
result
in
misalignment
of

the side gears/splines. This
will
necessitate side
gear
re-alignment before
the
axle shaft
can be in­

stalled.
AXLE SHAFT REMOVAL
(1) Raise and support the vehicle.
(2) Remove the wheel.
(3) Remove the brake drum.
(4) Clean all the foreign material from housing
cover area.
(5) Loosen the housing cover bolts. Drain the lubri­
cant from the housing. Remove the housing cover.

(6)
Rotate the differential case so the pinion mate
gear shaft lock screw is accessible. Remove the lock screw and the pinion mate gear shaft from the case (Fig. 3).
