INSTALLATION
(1) Install replacement wheel stud into flange of
hub and bearing assembly. Install washers on wheel
stud, then install a wheel lug nut on stud with flat
side of lug nut against washers (Fig. 38).
(2) Tighten the wheel lug nut, pulling the wheel
stud into the flange of the hub and bearing assembly.

bearing flange, remove lug nut and washers from
wheel stud.(3) Install the brake drum or disc brake rotor and
caliper on the hub and bearing assembly.
(4) Install wheel and tire assembly on vehicle.
Tighten the wheel mounting stud nuts in proper
sequence until all nuts are torqued to half specifica-
tion. Then repeat the tightening sequence to the full
specified torque of 135 N´m (100 ft. lbs.).
(5) Lower vehicle to the ground.

TIRE PRESSURE MONITORING
DESCRIPTION
Some versions of this vehicle are equipped with a
Tire Pressure Monitoring (TPM) system. It monitors
air pressure in the four road tires. Pressure in the
spare tire is not monitored. There is a sensor (transmitter) in each of the vehi-
cle's four road wheels that is built in to the valve
stem. The system alerts the driver when tire pres-
sure falls outside predetermined thresholds (pressure
too low or too high). A message is then displayed on
the Compass Mini Trip Computer (CMTC). For further information, refer to the Owners Man-
ual or the appropriate diagnostic information.
OPERATION
The Tire Pressure Monitoring (TPM) system uses
radio and sensor technology to monitor tire air pres-
sure levels. Sensors, mounted to each road wheel as
part of the valve stem, transmit an RF frequency
indicating their individual pressure to a receiver
located in the Sentry Key Remote Entry Module
(SKREEM). These transmissions occur approximately
once every minute at speeds over 13 mph (20 km/h).
The Tire Pressure Monitoring system remains active
even if no tire pressure related message is displayed.
SENSOR - TPM
DESCRIPTION
On vehicles equipped with Tire Pressure Monitor-
ing, one tire pressure sensor is mounted to each
wheel (Fig. 2). Each sensor has an internal battery
that lasts up to 10 years. The battery is not service-
able. At the time of battery failure, the sensor must
be replaced. The serviceable components of the tire
pressure sensor are: ² Sensor-To-Wheel Grommet
² Valve Stem Cap
² Valve Stem Core
Valve stem caps and cores are specifically designed
for the tire pressure monitoring sensors. Although
similar to standard valve stem caps and cores, they
are different.
CAUTION: Do not use a standard valve stem cap or
core in a tire pressure sensor. Always use the orig-
inal equipment style sensor cap and core.
CAUTION: Do not reuse the Sensor-To Wheel Grom-
met. Always use a new grommet when installing a
pressure sensor and properly torque the sensor
nut.
RS TIRES/WHEELS22s-1
INSTALLATION
NOTE: Before reinstalling a tire pressure sensor,
replace sealing grommet at base of valve stem.(1) Wipe area clean where sensor sealing grommet
contacts wheel. Make sure surface of wheel is not
damaged. (2) Install sensor in wheel as shown (Fig. 2). Do
not attempt to mount sensor otherwise, damage may
occur. (3) Using a thin wall socket, install special sensor
nut (Fig. 2). Tighten nut to 4 N´m (35 in. lbs.) torque.
CAUTION: Over-torquing the sensor nut by as little
as 12 N´m (106 in. lbs.) may result in sensor sepa-
ration from the valve stem. Under this condition,
the sensor may still function, however, the condi-
tion should be corrected immediately.
(4) Mount tire on wheel following tire changer
manufacturers instructions, paying special attention
to the following to avoid damaging tire pressure sen-
sor: (a) Rotating Wheel Tire Changers - Once the
wheel is mounted to the changer, position the sen-
sor valve stem approximately 210É from the head
of the changer in a clockwise direction before rotat-
ing the wheel (also in a clockwise direction) to
mount the tire (Fig. 3). Use this procedure on both
the upper and lower tire beads. (b) Rotating Tool Tire Changers - Position the
wheel on the changer so that the sensor valve stem
is approximately 210É from the head of the changer
in a clockwise direction from the mounting end of
the tool (Fig. 4) Make sure the sensor is clear of
the lower bead breaker area to avoid damaging the
sensor when the breaker rises (Fig. 4). Rotate the
tool in a counterclockwise direction to mount the
tire. Use this procedure on both the upper and
lower tire beads.

pressures may increase from 2 to 6 pounds per
square inch (psi) (14 to 41 kPa) during operation. Do
not reduce this normal pressure buildup.Improper inflation can cause:
² Uneven wear patterns
² Reduced tread life
² Reduced fuel economy
² Unsatisfactory ride
² The vehicle to drift.
WARNING: OVER OR UNDER INFLATED TIRES CAN
AFFECT VEHICLE HANDLING. THE TIRE CAN FAIL
SUDDENLY, RESULTING IN LOSS OF VEHICLE
CONTROL. Under inflation causes rapid shoulder wear, tire
flexing, and can result in tire failure (Fig. 4).
Over inflation causes rapid center wear and loss of
the tire's ability to cushion shocks (Fig. 5).STANDARD PROCEDURE - TIRE PRESSURE
FOR HIGH SPEED OPERATION
DaimlerChrysler Corporation advocates driving at
safe speeds within posted speed limits. Where speed
limits allow the vehicle to be driven at high speeds,
correct tire inflation pressure is very important.
Vehicles loaded to maximum capacity should not be
driven at continuous speeds over 120 km/h (75 mph).
Never exceed the maximum speed capacity of the
tire. For information on tire identification and speed
ratings, (Refer to 22 - TIRES/WHEELS/TIRES -
DESCRIPTION).
STANDARD PROCEDURE - TIRE LEAK
REPAIRING
For proper repairing, a radial tire must be removed
from the wheel. Repairs should only be made if the
defect, or puncture, is in the tread area (Fig. 6). The
tire should be replaced if the puncture is located in
the sidewall. Deflate tire completely before attempting to dis-
mount the tire from the wheel. Use a lubricant
such as a mild soap solution when dismounting
or mounting tire. Use tools free of burrs or sharp
edges which could damage the tire or wheel rim. Before mounting tire on wheel, make sure all rust
is removed from the rim bead and repaint if neces-
sary. Install wheel on vehicle, and progressively tighten
the 5 wheel nuts to a torque of 135 N´m (100 ft. lbs.).

REAR QUARTER PANEL/
FENDER AIR EXHAUSTER
DESCRIPTION
Air exhausters, designed to conform to the body
structure, allow air entering at the front of the vehi-
cle to flow out the back. By reducing air pressure
within the vehicle, the exhausters also reduce blower
noise at any given air flow level compared to operat-
ing without them and help reduce door closing effort.
They are located in the lower rear comers of the
body.
REMOVAL
SHORT WHEELBASE
(1) Remove the rear fascia from the body. (Refer to
13 - FRAMES & BUMPERS/BUMPERS/REAR FAS-
CIA - REMOVAL).
(2) Using a trim stick or another suitable wide flat
bladed tool, carefully pry the air exhauster away
from the opening in the lower aperture panel until
the snap features release (Fig. 19).
(3) Remove the air exhauster from the hole in the
lower aperture panel.
LONG WHEELBASE
NOTE: Models with the optional rear heater and air
conditioner do not have an air exhauster on the
right side of the vehicle, but have a plastic plug
installed in the right lower aperture panel. This plug
is removed using the same procedure used toremove the air exhauster from the short wheelbase
model. Refer to SHORT WHEELBASE.
(1) Remove the quarter trim panel from the inside
of the left or right quarter inner panel (Refer to 23 -
BODY/INTERIOR/RIGHT QUARTER TRIM PANEL
- REMOVAL) or (Refer to 23 - BODY/INTERIOR/
LEFT QUARTER TRIM PANEL - REMOVAL).
(2) Using a trim stick or another suitable wide flat
bladed tool, carefully pry the air exhauster away
from the opening in the lower aperture panel until
the snap features release (Fig. 20).
(1) Remove the air exhauster from the hole in the
lower aperture panel.
