TOWING-FRONT END LIFTED (SLING-TYPE)
CAUTION: Many vehicles are equipped with air
dams, spoilers, and/or ground effect panels. To
avoid component damage, a wheel-lift towing vehi-
cle or a flat-bed hauling vehicle is recommended.
If a 2WD XJ vehicle cannot be towed with the rear
wheels lifted, it can be towed with the front wheels
lifted.
(1) Attach a J-hook to the disabled vehicle at the
left side of the axle.
(2) Position the sling crossbar close to the J-hook
and below the front bumper.
(3) Secure a chain to the right side of vehicle by
placing it over the axle shaft tube and attaching it to
a structural member (Fig. 5).
(4) Attach the safety chains to the vehicle.
(5) Turn the ignition switch to the OFF position to
unlock the steering wheel.
2WD-AUTOMATIC TRANSMISSION
Provided the transmission is operable, tow only in
NEUTRALat speeds not to exceed 30 mph (50
km/h) and distances less than 15 miles (25km/h).
If the vehicle is to be towed more than 15 miles,
the propeller shaft should be disconnected or place
tow dollies under rear wheels.
2WD-MANUAL TRANSMISSION
To reduce the possible damage of transmission com-
ponents, the propeller shaft must be removed or
place tow dollies under the rear wheels before tow-
ing. Refer to Propeller Shafts, Group 16 for proper
removal procedure.
FOUR-WHEEL-DRIVE VEHICLE TOWING
Chrysler Corporation recommends that a vehicle be
transported on a flat-bed device. A Wheel-lift or
Sling-type device can be used provided all the wheels
are lifted off the ground using tow dollies.

CLUTCH AND BRAKE PEDAL BUSHINGS
If the clutch and brake pedal mechanism squeaks,
the pivot bushings should be lubricated. Use Mopar
Multi-Purpose Lubricant, or an equivalent. Refer to
Group 5, Brakes for location of bushings.
CLUTCH MASTER CYLINDER
LEVEL INSPECTION
WARNING: DO NOT ALLOW PETROLEUM OR WA-
TER BASE LIQUIDS TO CONTAMINATE CLUTCH
FLUID, SEAL DAMAGE AND CLUTCH FAILURE CAN
RESULT.
The clutch reservoir level should be inspected when
other underhood service is performed. (Fig. 1)
The fluid level is determined by its height in rela-
tion to the level indicator ring (Fig. 2) located inside
the reservoir. Add fluid until the height is level with
the indicator ring.
FLUID SPECIFICATION
Use Mopar, Brake And Hydraulic Clutch Fluid or
equivalent. Use only brake fluid conforming to DOT
3, Federal, Department of Transportation specifica-
tion. To avoid fluid contamination, use fluid from a
properly sealed container.CAUTION: Never use reclaimed brake fluid or fluid
from an unsealed container. In addition, do not use
fluid from a container that has been opened and al-
lowed to stand for an extended length of time.
Moisture in the air can be absorbed by the fluid,
which causes dilution with loss of effectiveness.
MANUAL TRANSMISSION
The manual transmission should be inspected for
oil leaks and proper oil level when other under vehi-
cle service is performed.
LUBRICANT SPECIFICATION
When it becomes necessary to add to or change the
lube oil in a Jeep manual transmission, use SAE
75W-90, API Quality Grade GL-5 gear lubricant.
LUBRICANT LEVEL
The fill-hole plug for all manual transmissions is
located on the right side of the case (Fig. 3). Deter-
mine the lubricant level according to the following
procedure.
(1) Remove the fill-hole plug (Fig. 3) from the
transmission. The lube oil should be level with the
bottom edge of the fill hole. The level can be slightly
below the bottom edge of the fill hole if the lube oil is
cold.

0 - 22 LUBRICATION AND MAINTENANCEJ

If the transmission is warm, lube oil could
drip out of the fill hole. This is acceptable but
the lube oil should not gush out of the fill hole.
(2) If not acceptable, raise the lube oil level to the
bottom edge of the transmission fill hole.
Add lube oil in small amounts to raise the
level.
(3) Install the fill-hole plug in the transmission.
Tighten the plug with 37 Nzm (27 ft. lbs.) torque.
LUBE OIL CHANGE
When it becomes necessary to change manual
transmission lube oil, use the following procedure.
(1) Raise and support the vehicle.
(2) Remove the fill-hole plug from the transmis-
sion.
(3) Place a container to collect the lube oil under
the transmission drain-hole plug.
(4) Remove the drain-hole plug and drain the lube
oil from the transmission into the container.
Care should be exercised when disposing
used lube oil after it has been drained from a
transmission.
(5) Install the drain-hole plug in the transmission.
Tighten the plug with 37 Nzm (27 ft. lbs.) torque.
(6) Fill the transmission until the lube oil begins to
drip out of the fill hole.
(7) Install the fill-hole plug in the transmission.
Tighten the plug with 37 Nzm (27 ft. lbs.) torque.
(8) Remove the support and lower the vehicle.
AUTOMATIC TRANSMISSION
The automatic transmission fluid should be
changed and bands adjusted at the intervals de-
scribed in the Maintenance Schedules section of this
Group. The automatic transmission should be in-
spected for fluid leaks and proper fluid level whenother under hood service is performed. Refer to
Group 21, Transmission for proper service proce-
dures.
CAUTION: To minimize fluid contamination, verify
that dipstick is seated in the fill tube after fluid level
reading is taken.
TO INSPECT THE TRANSMISSION FLUID
LEVEL
WARNING: USE EXTREME CAUTION WHEN THE
ENGINE IS OPERATING. DO NOT PUT YOUR
HANDS NEAR THE DRIVE BELT, PULLEYS OR FAN
BLADE. DO NOT STAND IN A DIRECT LINE WITH
THE FAN BLADE.
(1) Be sure transmission fluid is at normal operat-
ing temperature. Normal operating temperature is
reached after approximately 15 miles (25km) of oper-
ation.
(2) Position the vehicle on a level surface. This is
important for an accurate fluid level check.
(3) While sitting in driver seat, apply brakes and
place gear selector in each position, then move the
selector to:
²XJ vehicles-P (Park).
²YJ vehicles-N (Neutral).
(4) Apply parking brake.
(5) Raise hood and wipe off dipstick handle to pre-
vent dirt from entering fill tube. Then remove trans-
mission fluid level indicator (dipstick) and wipe clean
with a wiping cloth.
(6) Install dipstick and verify it is seated in fill
hole or tube.
(7) Remove dipstick, with handle above tip, take
fluid level reading. If the vehicle has been driven for
at least 15 minutes before inspecting fluid level,
transmission can be considered hot and reading
should be in the OK area. If vehicle has run for less
than 15 minutes and more than 60 seconds transmis-
sion can be considered warm and reading should be
above MIN mark. Add fluid only if level is below
MIN mark on dipstick when transmission is warm
(Fig. 4).
CAUTION: Do not overfill automatic transmission,
leakage or damage can result.
AUTOMATIC TRANSMISSION FLUID
SPECIFICATION
When it becomes necessary to add fluid or when
the ATF is replaced, use:
²MOPAR Dexron IIE/Mercon ATFonlyfor AW-4
automatic transmissions (XJ vehicles).
²MOPAR ATF PLUS type 7176 (YJ vehicles).

SPECIAL ADDITIVES
The addition of any special-type fluid to a Jeep au-
tomatic transmission is not recommended. The only
exception is the addition of black-light detection dye
to aid in detecting the source of ATF leaks. The use
of transmission sealing additives should also be
avoided.
Black-light detection dye is factory-installed
in automatic transmissions and, unless the ATF
has been drained and re-placed, it is not neces-
sary to add dye.
FLUID AND FILTER CHANGE
The automatic transmission fluid and filter should
be changed at the intervals described in the Mainte-
nance Schedules section of this Group. Refer to
Group 21, Transmission for proper service proce-
dures.
TRANSFER CASE (4WD VEHICLES)
The transfer case should be inspected for fluid
leaks and proper fluid level when other under vehicle
service is performed.
FLUID LEVEL
The transfer case fill hole plug is located at the
rear of the housing (Fig. 5).
Determine the transfer case fluid (ATF) level ac-
cording to the following procedure.(1) Raise and support the vehicle.
(2) Remove the fill hole plug from the transfer case
(Fig. 5). The fluid (ATF) level should be at the bottom
edge of the fill hole. The level can be slightly below
the bottom edge of the fill hole if the fluid is cold.
(3) If the level is not acceptable, raise the fluid
level to the bottom edge of the fill hole.
(4) Install the fill hole plug (Fig. 5). Tighten the fill
hole plug to 48 Nzm (35 ft-lbs) torque.
(5) Remove the support and lower the vehicle.
FLUID DRAIN AND REFILL
The Transfer Case should be serviced as specified
in the Lubrication and Maintenance Schedules.
(1) Raise and support the vehicle.
(2) Remove the fill hole plug (Fig. 5) from the
transfer case.
(3) Place an appropriate container under the trans-
fer case drain hole plug (Fig. 5).
(4) Remove the drain hole plug and drain the ATF
from the transfer case into the container.
CAUTION: Do not over-tighten the drain and fill hole
plugs. Over-tightening can strip the hole threads
and/or crack the aluminum housing.
(5) Install the drain hole plug in the transfer case.
Tighten the drain hole plug to 27 Nzm (20 ft-lbs)
torque.
(6) Fill the transfer case to the bottom edge of the
fill hole.

FLUID SPECIFICATION
If it is necessary to add fluid to a transfer case (or
when the fluid is changed), use MOPAR ATF PLUS
type 7176 or an equivalent Mercon/Dexron III ATF.
FRONT AND REAR AXLES
The front and rear axles should be inspected for
fluid leaks and proper fluid level when other under
vehicle service is performed. Refer to the Lubrication
and Maintenance Schedule service intervals.
LUBRICANT SPECIFICATIONS
For normal vehicle operation, use SAE 75W-90,
API Quality Grade GL-5 gear lubricant in all Jeep
front (4WD only) and rear axles. Vehicles equipped
with a Trac-Lok rear axle also require a friction mod-
ifier additive included with the gear lubricant.
When involved in trailer towing applications
use SAE 80W-140, API Quality Grade GL-5 gear
lubricant in the rear axle. XJ Vehicles equipped
with a class III trailer hitch require SAE 75W-
140 synthetic gear lubricant in the rear axle.

Axle shaft bearings produce noise and vibration
when worn or damaged. The noise generally changes
when the bearings are loaded. Road test the vehicle.
Turn the vehicle sharply to the left and to the right.
This will load the bearings and change the noise
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:
²Damaged drive shaft
²Missing drive shaft balance weight
²Worn, out-of-balance wheels
²Loose wheel lug nuts
²Worn U-joint
²Loose spring U-bolts
²Loose/broken springs
²Damaged axle shaft bearings
²Loose pinion gear nut
²Excessive pinion yoke run out²Bent 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 22ÐTires And Wheels for addi-
tional information involving vibration diagnosis.
DRIVELINE SNAP
A snap or clunk noise when the vehicle is shifted
into gear (or the clutch engaged), can be caused by:
²High engine idle speed
²Loose engine/transmission/transfer case mounts
²Worn U-joints
²Loose spring mounts
²Loose pinion gear nut and yoke
²Excessive ring gear backlash
²Excessive differential side gear-to-case clearance
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.

(6) Remove the remaining bearing cap, bearings,
seals and spider from the propeller shaft yoke.
CLEANING AND INSPECTION
(1) Clean all the U-joint yoke bores with cleaning
solvent and a wire brush. Ensure that all the rust
and foreign matter are removed from the bores.
(2) Inspect the yokes for distortion, cracks and
worn bearing cap bores.
(3) Replace the complete U-joint if any of the com-
ponents are defective.
ASSEMBLY
(1) Pack the bearing caps 1/3 full of wheel bearing
lubricant. Apply extreme pressure (EP), lithium-base
lubricant to aid in installation.
(2) Position the spider in the yoke. Insert the seals

REAR AXLE ALIGNMENT
MEASUREMENT
The following procedure can be used to determine
if abnormal rear tire tread wear is the result of a
bent or deformed rear axle shaft.
(1) Raise both rear wheels off the surface with a
frame contact hoist.
(2) Attach a one-inch long piece of masking tape at
the center of each tire tread for use as reference marks.
(3) Rotate the rear wheels until both reference
marks face the front of the vehicle. Measure the dis-
tance between the outside edges of the two pieces of
tape. Record this measurement as the front of tire
(FTR) measurement.
(4) Rotate the rear wheels until both reference
marks face the rear of the vehicle. Measure the dis-
tance between the outside edges of the two pieces of
tape. Record this measurement as the rear of tire
(RTR) measurement.
(5) Subtract the (RTR) measurement from the
(FTR) measurement to obtain the amount of wheel
toe. The acceptable rear wheel toe-in position is 1/16
inch (1.6 mm) to 3/16 inch (4.8 mm) toe-out.
(6) Rotate the rear wheels until the reference
marks are facing downward. Measure the distance
between the outside edges of the two pieces of tape.
Record this measurement as the bottom of tire (BTR)
measurement.
(7) Average the (FTR) and the (RTR) distance mea-
surements. Subtract the (BTR) measurement from
this average distance to obtain the camber. The ac-
ceptable amount of camber is 1/16 inch to 3/32 inch
(1.6 to 2.4 mm).
(FTR + RTR) DIVIDED BY 2 (TWO) MINUS
BTR EQUALS CAMBER
If the (BTR) distance measurement is less
than the average FTR and RTR distance mea-
surement, the camber will be positive(+).If
the (BTR) distance measurement is greater
than the average FTR and RTR distance, the
camber will be negative(-).
If the toe position or camber is not acceptable, a bent
or deformed rear axle shaft is most likely the cause.
LIMITED SLIP DIFFERENTIAL
Under normal traction conditions, engine torque is di-
vided evenly. With low-traction surfaces, engine torque
is transferred to the wheel with the most tire traction.
When diagnosing a limited-slip differential 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.
²With Trac-LokŸ differentials add a container of
MOPAR Trac-Lok Lubricant.
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.
