MAINTENANCE SCHEDULES
INTRODUCTION
There are two maintenance schedules that show
proper service intervals for Jeep Cherokee and Jeep
Wrangler vehicles. Use the schedule that best de-
scribes the conditions the vehicle is operated under.
When mileage and time is listed, follow the interval
that occurs first.
ScheduleÐAlists all the scheduled maintenance
to be performed under normal operating conditions.
ScheduleÐBis a schedule for vehicles that are
usually operated under one or more of the following
conditions.
²Frequent short trip driving less than 5 miles (8
km).
²Frequent driving in dusty conditions.
²Trailer towing or heavy load hauling.
²Frequent long periods of engine idling.
²Sustained high speed operation.
²Desert operation.
²Frequent starting and stopping.
²Cold climate operation.
²Off road driving.
²Commercial service.
²Snow plow operation.
²More than half of vehicle operation occurs in
heavy city traffic during hot weather (above 90É F).
AT EACH STOP FOR GASOLINE
²Check engine oil level and add as required.
²Check windshield washer solvent and add as re-
quired.
ONCE A MONTH
²Check tire pressure and look for unusual tire wear
or damage.
²Check fluid levels of coolant reservoir, brake mas-
ter cylinder, power steering and transmission. Add
fluid as required.
²Check all lights and other electrical items for cor-
rect operation.
²Inspect battery and clean and tighten terminals as
required.
²Check rubber seals on each side of the radiator for
proper fit.
AT EACH OIL CHANGE
²Inspect exhaust system.
²Inspect brake hoses.
²Rotate the tires at each oil change interval shown
on ScheduleÐA: (7,500 Miles) or every other interval
shown on ScheduleÐB: (6,000 Miles).
²Check engine coolant level, hoses, and clamps.
²Lubricate 4x4 steering linkage.
²Lubricate propeller shaft universal joints and slip
spline, if equipped.After completion of off-road (4WD) operation, the
underside of the vehicle should be thoroughly in-
spected. Examine threaded fasteners for looseness.
HARSH SURFACE ENVIRONMENTS
After vehicle operation in a harsh surface environ-
ment, the following components should be inspected
and cleaned as soon as possible:
²Brake drums.
²Brake linings.
²Front wheel bearings (2WD vehicles only).
²Axle coupling joints.
This will prevent wear and/or unpredictable brake
action.

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.
Fig. 1 Clutch Reservoir LocationÐTypical
Fig. 2 Hydraulic Clutch Fluid LevelÐTypical
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

lubricant equivalent to lubricate the steering linkage.
INSPECTION
(1) Inspect the steering linkage. Examine the tie
rods and the drag link for bending, and the ball
studs for looseness and excessive wear.(2) Replace, as necessary, all torn/ruptured ball-
stud seals and damaged/defective steering linkage
components.
CAUTION: Use care to prevent lubricant from con-
tacting the brake rotors.
FRONT WHEEL BEARINGS
Some 2WD XJ vehicles are equipped with service-
able front wheel bearings. XJ 4WD vehicles have
semi-floating axle shafts and axle shaft bearings that
are lubricated via differential lube oil.
RECOMMENDED MAINTENANCEÐ2WD XJ
VEHICLES
If equipped, the serviceable front wheel bearings
should be lubricated (re-packed) at the same time as
front brake pad/caliper service is conducted.
LUBRICANT SPECIFICATION

hose unless the caliper must also be removed
for maintenance.Support the caliper with a
hanger to prevent brake fluid hose damage.
(2) Remove the dust cap, the cotter pin, the nut re-
tainer, the adjustment nut, and the thrust washer
from the spindle (Fig. 3). Discard the cotter pin.
(3) Remove the wheel outer bearing from the hub.
(4) Remove the wheel hub/disc brake rotor from
the spindle.
(5) Remove the seal and the inner wheel bearing
from the hub cavity.
(6) After removal, inspect both front wheel bearing
races for indications of pitting, brinelling and exces-
sive heat.
(7) Wipe the spindle clean and apply a small
amount of chassis/wheel bearing lubricant (NLGI
GC-LB lubricant) to prevent rust. Wipe the wheel
hub cavity clean.
CAUTION: Do not over-fill the wheel hub cavity with
lubricant. Excessive lubricant can cause overheat-
ing and bearing damage. Also, excessive lubricant
can be forced out of the wheel hub cavity and con-
taminate the brake rotor/pads.
(8) Partially fill the wheel hub cavity with chassis/
wheel bearing lubricant (NLGI GC-LB lubricant).
(9) Pack the wheel bearings with chassis/wheel
bearing lubricant (NLGI GC-LB lubricant). Ensure
that sufficient lubricant is forced between the bear-
ing rollers.
(10) Install the wheel inner bearing in the wheel
hub and install a replacement seal.
(11) Clean the disc brake rotor contact surfaces, if
necessary.
(12) Install the wheel hub/disc brake rotor on the

FLUID LEVEL
The fluid level indicator (dipstick) is attached to
the reservoir cap (Fig. 6). The fluid level in the res-
ervoir can be determined with the fluid either hot or
cold.
(1) Remove the cap from the reservoir.
(2) Depending on fluid temperature, if the level is
below the FULL HOT mark or the FULL COLD
mark on the dipstick, add power steering fluid.
(3) Install the cap on the reservoir.CAUTION: Do not over fill power steering reservoir
when adding fluid, seal damage and leakage can re-
sult.
MANUAL STEERING GEAR
The manual steering gear should be inspected for
damage at the same time as the engine oil is
changed and the oil filter is replaced. Refer to Group
19, Steering for additional information and service
procedures.
POWER BRAKE SYSTEM
RECOMMENDED MAINTENANCE
The brake fluid level (Fig. 8) should be inspected
when other underhood service is done. With disc-
brakes, the fluid level can be expected to fall as the
brake pads wear. However, a low fluid level can also
be caused by a leak, and repair will then be neces-
sary. Refer to Group 5, Brakes for proper service pro-
cedures.
In addition, the brake system should be operation-
ally tested periodically to ensure that it is function-
ing normally.
FLUID SPECIFICATION
Jeep power brake systems require MOPAR Heavy-
Duty Brake Fluid, or an equivalent product identified
as conforming to FMVSS No. 116, DOT-3 and SAE
J-1703 specifications.
Use brake fluid from properly sealed container
when adding fluid to the reservoir. Never use re-
claimed fluid or fluid that does not conform to the
DOT/SAE Standards.
CAUTION: Use of a brake fluid that has a lower ini-
tial boiling point then specified by FMVSS No. 116,
DOT 3 and SAE J-1703 could result in sudden brake
failure during hard, prolonged braking.
Do not allow petroleum base fluids to contaminate
the brake fluid. Seal damage will result.
BRAKE FLUID LEVEL
STANDARD POWER BRAKE SYSTEM
(1) Clean the cover and the sides of the brake fluid
reservoir.
(2) Detach the bail retainer from the reservoir
cover and remove the cover from the reservoir.
(3) The brake fluid level should be 6 mm (1/4 in)
below the rim of each reservoir well for XJ and YJ
Vehicles (Fig. 7 and 8). If not, add brake fluid as nec-
essary.
(4) Inspect the reservoir cover bail retainer for ten-
sion and the cover for proper fit. The cover should fit
tight and have a good seal.
