GEAR
DESCRIPTION
A rack and pinion steering gear (Fig. 1) is made up
of two main components, the pinon shaft and the
rack. The gear cannot be adjusted or internally ser-
viced. If a malfunction or a fluid leak occurs, the gear
must be replaced as an assembly.
OPERATION
The steering column intermediate shaft is attached
to the gear pinion. The rotation of the pinion moves
the gear rack from side-to-side. This lateral action of
the rack pushes and pulls the tie rods, which are
connected to the steering knuckles to change the
direction of the front wheels.

POWER STEERING PRESSURE
SWITCH
DESCRIPTION
A pressure sensing switch is used in the power
steering system. It is mounted on the high-pressure
steering hose. This switch will be used with both
2.4L and 3.7L engines.
OPERATION
The switch is used on both the 2.4L 4±cylinder and
3.7L V-6 engines.
The power steering pressure switch provides an
input to the Powertrain Control Module (PCM). This
input is provided during periods of high steering
pump load and low engine rpm; such as during park-
ing maneuvers. The PCM increases the idle speed
through the Idle Air Control (IAC) motor. This is
done to prevent the engine from stalling under the
increased load.
When steering pump pressure exceeds 3275 kPa  
690 kPa (475 psi   100 psi), the Normally Closed
(NC) switch will open and the PCM will increase the
engine idle speed. This will prevent the engine from
stalling.
When pump pressure drops to approximately 1379
kPa (200 psi), the switch circuit will re-close and
engine idle speed will return to its previous setting.
REMOVAL
The power steering pressure switch is installed in
the power steering high-pressure hose (Fig. 9).
(1) Remove the high pressure power steering
hose(Refer to 19 - STEERING/PUMP/HOSES -
REMOVAL).
(2) Disconnect electrical connector from power
steering pressure switch.
(3) Place a small container or shop towel beneath
switch to collect any excess fluid.
(4) Remove switch. Use back-up wrench on power
steering line to prevent line bending.
INSTALLATION
(1) Install power steering switch into power steer-
ing line. (Fig. 9)
(2) Tighten to 9.6 N´m (85 in. lbs.) torque.

DIAGNOSIS AND TESTING - TREAD WEAR
INDICATORS
Tread wear indicators are molded into the bottom
of the tread grooves. When tread depth is 1.6 mm
(1/16 in.), the tread wear indicators will appear as a
13 mm (1/2 in.) band (Fig. 14).
Tire replacement is necessary when indicators
appear in two or more grooves or if localized balding
occurs.
DIAGNOSIS AND TESTING - TIRE WEAR
PATTERNS
Under inflation will cause wear on the shoulders of
tire. Over inflation will cause wear at the center of
tire.
Excessive camber causes the tire to run at an
angle to the road. One side of tread is then worn
more than the other (Fig. 15).
Excessive toe-in or toe-out causes wear on the
tread edges and a feathered effect across the tread
(Fig. 15).
DIAGNOSIS AND TESTING - TIRE NOISE OR
VIBRATION
Radial-ply tires are sensitive to force impulses
caused by improper mounting, vibration, wheel
defects, or possibly tire imbalance.
To find out if tires are causing the noise or vibra-
tion, drive the vehicle over a smooth road at varyingspeeds. Note the noise level during acceleration,
deceleration and slight left and right steering inputs.
STANDARD PROCEDURE - REPAIRING LEAKS
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. 16). The
tire should be replaced if the puncture is located in
the sidewall.
Deflate tire completely before removing the tire
from the wheel. Use lubrication such as a mild soap
solution when dismounting or mounting tire. Use
tools free of burrs or sharp edges which could dam-
age 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 tighten to proper
torque specification.
CLEANING
Remove the protective coating on the tires before
delivery of a vehicle. This coating may cause deteri-
oration of the tires.
To remove the protective coating, apply warm
water and let it soak for a few minutes. Afterwards,
scrub the coating away with a soft bristle brush.
Steam cleaning may also be used to remove the coat-
ing.
NOTE: DO NOT use gasoline, mineral oil, oil-based
solvent or a wire brush for cleaning.

²USE A OSHA APPROVED BREATHING FILTER
WHEN SPRAYING PAINT OR SOLVENTS IN A CON-
FINED AREA. PERSONAL INJURY CAN RESULT.
²AVOID PROLONGED SKIN CONTACT WITH

²DO NOT STAND UNDER A HOISTED VEHICLE
THAT IS NOT PROPERLY SUPPORTED ON SAFETY
STANDS. PERSONAL INJURY CAN RESULT.
CAUTION: When holes must be drilled or punched
in an inner body panel, verify depth of space to the
outer body panel, electrical wiring, or other compo-
nents. Damage to vehicle can result.
²Do not weld exterior panels unless combustible
material on the interior of vehicle is removed from
the repair area. Fire or hazardous conditions, can
result.
²Always have a fire extinguisher ready for use
when welding.
²Disconnect the negative (-) cable clamp from
the battery when servicing electrical components
that are live when the ignition is OFF. Damage to
electrical system can result.²Do not use abrasive chemicals or compounds
on painted surfaces. Damage to finish can result.
²Do not use harsh alkaline based cleaning sol-
vents on painted or upholstered surfaces. Damage
to finish or color can result.
²Do not hammer or pound on plastic trim panel
when servicing interior trim. Plastic panels can
break.
DaimlerChrysler Corporation uses many different
types of push-in fasteners to secure the interior and
exterior trim to the body. Most of these fasteners can
be reused to assemble the trim during various repair
procedures. At times, a push-in fastener cannot be
removed without damaging the fastener or the com-
ponent it is holding. If it is not possible to remove a
fastener without damaging a component or body, cut
or break the fastener and use a new one when
installing the component. Never pry or pound on a
plastic or pressed-board trim component. Using a
suitable fork-type prying device, pry the fastener
from the retaining hole behind the component being
removed. When installing, verify fastener alignment
with the retaining hole by hand. Push directly on or
over the fastener until it seats. Apply a low-force pull
to the panel to verify that it is secure.
When it is necessary to remove components to ser-
vice another, it should not be necessary to apply
excessive force or bend a component to remove it.
Before damaging a trim component, verify hidden
fasteners or captured edges holding the component in
place.

PAINT TOUCH-UP
DESCRIPTION
When a painted metal surface has been scratched
or chipped, it should be touched-up as soon as possi-
ble to avoid corrosion. For best results, use Mopart
Scratch Filler/Primer, Touch-Up Paints and Clear Top
Coat. Refer to Introduction group of this manual for
Body Code Plate information.
WARNING: USE AN OSHA APPROVED BREATHING
FILTER WHEN SPRAYING PAINT OR SOLVENTS IN
A CONFINED AREA. PERSONAL INJURY CAN
RESULT.
OPERATION
(1) Scrape loose paint and corrosion from inside
scratch or chip.
(2) Clean affected area with MopartTar/Road Oil
Remover, and allow to dry.
(3) Fill the inside of the scratch or chip with a coat
of filler/primer. Do not overlap primer onto good sur-
face finish. The applicator brush should be wet
enough to puddle-fill the defect without running. Do
not stroke brush applicator on body surface. Allow
the filler/primer to dry hard.
(4) Cover the filler/primer with color touch-up
paint. Do not overlap touch-up color onto the originalcolor coat around the scratch or chip. Butt the new
color to the original color, if possible. Do not stroke
applicator brush on body surface. Allow touch-up
paint to dry hard.
(5) On vehicles without clear coat, the touch-up
color can be lightly finesse sanded (1500 grit) and
polished with rubbing compound.
(6) On vehicles with clear coat, apply clear top coat
to touch-up paint with the same technique as
described in Step 4. Allow clear top coat to dry hard.
If desired, Step 5 can be performed on clear top coat.
WARNING: AVOID PROLONGED SKIN CONTACT
WITH PETROLEUM OR ALCOHOL ± BASED CLEAN-
ING SOLVENTS. PERSONAL INJURY CAN RESULT.
AVOID PROLONGED SKIN CONTACT WITH PETRO-
LEUM OR ALCOHOL ± BASED CLEANING SOL-
VENTS. PERSONAL INJURY CAN RESULT.
FINESSE SANDING/BUFFING &
POLISHING
DESCRIPTION
Minor acid etching, orange peel, or smudging in
clear coat or single-stage finishes can be reduced
with light finesse sanding, hand buffing, and polish-
ing.If the finish has been finesse sanded in the
past, it cannot be repeated. Finesse sanding
operation should be performed by a trained
automotive paint technician.
CAUTION: Do not remove clear coat finish, if
equipped. Base coat paint must retain clear coat for
durability.
