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.
(7) Install the fill hole plug in the transfer case
Tighten the plug to 27 Nzm (20 ft-lbs) torque.
(8) Remove the support and lower the vehicle.
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.

ALIGNMENT MEASUREMENTS AND ADJUSTMENTS
Before each alignment reading, the vehicle should
be jounced (rear first, then front). Grasp each
bumper at the center and jounce the vehicle up and
down several times. Always release the bumper in
the down position.Set the front end alignment to
specifications with the vehicle at its NOR-
MALLY RIDE HEIGHT.
CAMBER
The wheel camber angle is preset. This angle is not
adjustable and cannot be altered.
CASTER
Before checking the caster of the front axle for cor-
rect angle, be sure the axle is not bent or twisted.
Road test the vehicle, make left and right turns. If
the steering wheel returns to the center position un-
assisted, the caster angle is correct. If steering wheeldoes not return toward the center position unas-
sisted, an incorrect caster angle is probable.
Caster can be adjusted by installing the appropri-
ate size shims (Fig. 2, 3).Changing caster angle
will also change the front propeller shaft angle.
The propeller shaft angle has priority over
caster. Refer to Group 16, Propeller Shafts for
additional information.
TOE POSITIONÐXJ VEHICLES
