WARNING
WARNINGS AND CAUTIONS
(Refer to 8 - ELECTRICAL/RESTRAINTS - WARN-
ING)
WARNING: BEFORE BEGINNING ANY SERVICE
PROCEDURES THAT INVOLVES REMOVING THE
AIR BAG. REMOVE AND ISOLATE THE NEGATIVE
(-) BATTERY CABLE (GROUND) FROM THE VEHI-
CLE BATTERY. THIS IS THE ONLY SURE WAY TO
DISABLE THE AIR BAG SYSTEM. FAILURE TO DO
THIS COULD RESULT IN ACCIDENTAL AIR BAG
DEPLOYMENT AND POSSIBLE PERSONAL INJURY.

WARNING: THE AIR BAG SYSTEM IS A SENSITIVE,
COMPLEX ELECTRO-MECHANICAL UNIT. BEFORE
ATTEMPTING TO DIAGNOSE, REMOVE OR INSTALL
THE AIR BAG SYSTEM COMPONENTS YOU MUST
FIRST DISCONNECT AND ISOLATE THE BATTERY
NEGATIVE (GROUND) CABLE. THEN WAIT TWO
MINUTES FOR THE SYSTEM CAPACITOR TO DIS-
CHARGE. FAILURE TO DO SO COULD RESULT IN
ACCIDENTAL DEPLOYMENT OF THE AIR BAG AND
POSSIBLE PERSONAL INJURY. THE FASTENERS,
SCREWS, AND BOLTS, ORIGINALLY USED FOR
THE AIR BAG COMPONENTS, HAVE SPECIAL
COATINGS AND ARE SPECIFICALLY DESIGNED
FOR THE AIR BAG SYSTEM. THEY MUST NEVER
BE REPLACED WITH ANY SUBSTITUTES. ANYTIME
A NEW FASTENER IS NEEDED, REPLACE WITH
THE CORRECT FASTENERS PROVIDED IN THE
SERVICE PACKAGE OR FASTENERS LISTED IN
THE PARTS BOOKS.
WARNING: SAFETY GOGGLES SHOULD BE WORN
AT ALL TIMES WHEN WORKING ON STEERING
COLUMNS.
CAUTION: Disconnect negative (ground) cable from
the battery before servicing any column compo-
nent.
CAUTION: Do not attempt to remove the pivot pins
to disassemble the tilting mechanism. Damage will
occur.
DIAGNOSIS AND TESTING - STEERING
COLUMN
For diagnosis of conditions relating to the steering
column, (Refer to 19 - STEERING - DIAGNOSIS
AND TESTING).
REMOVAL
NOTE: Before proceeding, (Refer to 19 - STEERING/
COLUMN - WARNING)(Refer to 8 - ELECTRICAL/RE-
STRAINTS/DRIVER AIRBAG - REMOVAL).
(1) Make sure the front wheels of the vehicle are
in the STRAIGHT AHEAD position before beginning
the column removal procedure.
(2) Disconnect and isolate the negative (ground)
cable from the battery. Wait at least two minutes for
the airbag system reserve capacitor to discharge
before beginning any steering column, instrument
panel, or airbag system/component service.WARNING: WHEN AN UNDEPLOYED AIRBAG IS TO
BE REMOVED FROM THE VEHICLE, FIRST DISCON-
NECT AND ISOLATE THE BATTERY NEGATIVE
(GROUND) CABLE. ALLOW THE AIRBAG SYSTEM
RESERVE CAPACITOR TO DISCHARGE FOR TWO
MINUTES BEFORE BEGINNING ANY AIRBAG SYS-
TEM OR COMPONENT SERVICE. PERSONAL
INJURY MAY RESULT IF THIS PROCEDURE IS NOT
FOLLOWED.
(3) Remove the driver airbag mounting screws
(Fig. 2).
(4) Lift the airbag from its mount and disconnect
two airbag squib, speed control and horn connectors
(Fig. 3). Remove driver airbag. Properly store the
driver airbag out of the way. (Refer to 8 - ELECTRI-
CAL/RESTRAINTS - WARNING)
(5) Remove the steering wheel retaining bolt (Fig.
4).
(6) Remove damper (Fig. 4).
(7) If equipped, disconnect the remote audio con-
trol switch wiring from the clockspring (Fig. 4).
CAUTION: Do not bump or hammer on steering col-
umn or steering column shaft when removing steer-
ing wheel from steering column shaft.
CAUTION: When installing steering wheel puller
bolts in steering wheel, do not thread bolt into
steering wheel more than a half inch. If the bolts
are threaded into the steering wheel more than a
half inch they will contact and damage the clock-
spring.

gently press inward at seams between the two
shrouds at points of contact to disengage inner lock-
ing tabs, then remove upper shroud. If the vehicle is
equipped with traction control, the lower shroud will
need to be removed once the upper shroud is unfas-
tened in order to disconnect the traction control wir-

GEAR
DESCRIPTION
This vehicle is equipped with a rack and pinion
power steering gear (Fig. 1). It is mounted to the
underside of the front suspension cradle/crossmem-
ber.
The steering column is attached to the gear
through the use of an intermediate shaft and cou-
plers. The outer ends of the power steering gear's
outer tie rods connect to the steering knuckles.
NOTE: The power steering gear should NOT be ser-
viced or adjusted unless DaimlerChrysler Corpora-
tion authorizes. If a malfunction or oil leak occurs,
the complete steering gear should be replaced.
Only the outer tie rods may be replaced separately
from the rest of the gear.
OPERATION
Turning of the steering wheel is converted into lin-
ear (side-to-side) travel through the meshing of the
helical pinion teeth with the rack teeth in the steer-
ing gear. This travel pushes and pulls the tie rods to
change the direction of the vehicle's front wheels.
Power assist steering provided by the power steer-
ing pump is controlled by an open center, rotary type
control valve which directs oil from the pump to
either side of the integral rack piston upon demand.
Road feel is controlled by the diameter of a torsion
bar which initially steers the vehicle. As required
steering effort increases, as in a turn, the torsion bar
twists, causing relative rotary motion between the
rotary valve body and the valve spool. This move-
ment directs oil behind the integral rack piston
which, in turn, builds hydraulic pressure and assists
in the turning effort.Manual steering control of the vehicle can be main-
tained if power steering assist is lost. However,
under this condition, steering effort is significantly
increased.
WARNING
WARNINGS AND CAUTIONS
WARNING: POWER STEERING FLUID, ENGINE
PARTS AND EXHAUST SYSTEM MAY BE
EXTREMELY HOT IF ENGINE HAS BEEN RUNNING.
DO NOT START ENGINE WITH ANY LOOSE OR DIS-
CONNECTED HOSES. DO NOT ALLOW HOSES TO
TOUCH HOT EXHAUST MANIFOLD OR CATALYST.
WARNING: FLUID LEVEL SHOULD BE CHECKED
WITH THE ENGINE OFF TO PREVENT PERSONAL
INJURY FROM MOVING PARTS.
CAUTION: When the system is open, cap all open
ends of the hoses, power steering pump fittings or
power steering gear ports to prevent entry of for-
eign material into the components.
REMOVAL
REMOVAL - LHD GEAR
(1) Remove cap from power steering fluid reser-
voir.
(2) Using a siphon pump, remove as much fluid as
possible from the power steering fluid reservoir.Use
care not to damage the filter mesh below the
fluid surface.
