AIRBAG SYSTEM
WARNING: THE MECHANICAL AIRBAG SYSTEM IS
A SENSITIVE, COMPLEX MECHANICAL UNIT. BE-
FORE ATTEMPTING TO REMOVE OR INSTALL THE
AIRBAG SYSTEM OR RELATED STEERING WHEEL
AND STEERING COLUMN COMPONENTS YOU
MUST FIRST DISARM THE AIRBAG FIRING MECHA-
NISM. FAILURE TO DO SO COULD RESULT IN AC-
CIDENTAL DEPLOYMENT AND POSSIBLE INJURY.
WARNING: THE AIRBAG MODULE INFLATOR/SEN-
SOR ASSEMBLY CONTAINS SODIUM AZIDE AND
POTASSIUM NITRATE. THESE MATERIALS ARE
POISONOUS AND EXTREMELY FLAMMABLE. CON-
TACT WITH ACID, WATER OR HEAVY METALS MAY
PRODUCE HARMFUL AND IRRITATING GASES (SO-
DIUM HYDROXIDE IS FORMED IN THE PRESENCE
OF MOISTURE) OR COMBUSTIBLE COMPOUNDS.
DO NOT ATTEMPT TO DISMANTLE THE MODULE
OR TAMPER WITH ITS ARMING LEVER. DO NOT
PUNCTURE, INCINERATE, OR BRING INTO CON-
TACT WITH ELECTRICITY. DO NOT STORE AT TEM-
PERATURES EXCEEDING 200ÉF.WARNING: REPLACE AIRBAG SYSTEM COMPO-
NENTS WITH PARTS SPECIFIED IN THE CHRYSLER
MOPAR PARTS CATALOG ONLY. IT IS OF PARTICU-
LAR IMPORTANCE THAT ANY COMPONENTS USED
IN THIS MECHANICALLY-FIRED AIRBAG SYSTEM
NOT BE MIXED WITH COMPONENTS FROM AN
ELECTRICALLY-FIRED AIRBAG SYSTEM. SUBSTI-
TUTE PARTS MAY APPEAR THE SAME, BUT INTER-
NAL DIFFERENCES MAY RESULT IN INFERIOR
OCCUPANT PROTECTION.
WARNING: THE FASTENERS, SCREWS, AND
BOLTS, ORIGINALLY USED FOR THE AIRBAG COM-
PONENTS, HAVE SPECIAL COATINGS AND ARE
SPECIFICALLY DESIGNED FOR THE AIRBAG SYS-
TEM. THEY MUST NEVER BE REPLACED WITH ANY
SUBSTITUTES. ANYTIME A NEW FASTENER IS
NEEDED, REPLACE WITH THE CORRECT FASTEN-
ERS PROVIDED IN THE SERVICE PACKAGE OR
SPECIFIED IN THE CHRYSLER MOPAR PARTS CAT-

AIRBAG MODULE REMOVEÐINSTALL
WARNING: THIS AIRBAG SYSTEM IS A SENSITIVE,
COMPLEX MECHANICAL UNIT. BEFORE ATTEMPT-
ING TO REMOVE OR INSTALL THE AIRBAG SYS-
TEM OR RELATED STEERING WHEEL AND
STEERING COLUMN COMPONENTS YOU MUST
FIRST DISARM THE AIRBAG FIRING MECHANISM.
FAILURE TO DO SO COULD RESULT IN ACCIDEN-
TAL DEPLOYMENT AND POSSIBLE PERSONAL IN-
JURY.
When removing a deployed airbag module,
rubber gloves, eye protection and long-sleeved
shirt should be worn. There may be deposits on
the airbag module and other interior surfaces,
which can cause irritation to the skin and eyes
in large doses.
(1) Disconnect battery negative cable and isolate.
(2) Using a small screwdriver, remove plastic cover
plug from top outer surface of steering wheel hub
(Fig 2). Exit vehicle and disarm airbag by reaching
through driver's side window and turning arming
screw counter-clockwise to its travel limit (Fig 3 and
4 ). This is done using an 8mm socket and manual
drive. DO NOT USE POWER-DRIVEN TOOLS.
(3) From back side of steering wheel, remove 4
nuts attaching airbag module to steering wheel (Fig.
5). This is done using a 10mm socket and manual
drive. DO NOT USE POWER-DRIVEN TOOLS.
(4) Remove airbag module from steering wheel.
(5) Reverse removal procedures to install. Tighten
airbag module attaching nuts to 9 to 11 Nzm (80 to
100 in. lbs.). Exit vehicle and arm airbag by reaching
through driver's side window and turning arming
screw clockwise to its travel limit. Arming screw
torque should not exceed 1.1 to 1.7 Nzm (10-15 in.
lbs.). Reinstall plastic cover plug in steering wheel
hub.
STEERING WHEEL
WARNING: BEFORE ATTEMPTING TO REMOVE OR
INSTALL THE AIRBAG SYSTEM OR RELATED
STEERING WHEEL AND STEERING COLUMN COM-
PONENTS YOU MUST FIRST DISARM THE AIRBAG
FIRING MECHANISM. WHEN SERVICING AIR BAG
SYSTEM, REMOVE AND ISOLATE THE BATTERY
NEGATIVE (-) CABLE (GROUND) FROM THE VEHI-
CLE BATTERY. YOU MUST DISARM THE AIRBAG
FIRING MECHANISM. FAILURE TO DO SO COULD
RESULT IN ACCIDENTAL AIR BAG DEPLOYMENT
AND POSSIBLE INJURY. WHEN AN UNDEPLOYED
AIR BAG ASSEMBLY IS TO BE REMOVED FROM
THE STEERING WHEEL, DISCONNECT THE BAT-
TERY GROUND CABLE AND ISOLATE. THE ARMING
SCREW MUST BE USED TO DISARM THE AIRBAG.
REMOVAL
(1) Make sure the front wheels are in thestraight
aheadposition and steering column locked in place.

ASSEMBLY
WARNING: USE ONLY THE ORIGINAL OR EXACT
REPLACEMENT SCREWS, BOLTS AND NUTS TO
ASSEMBLE THE STEERING COLUMN. INCORRECT
SCREW OR BOLT LENGTH COULD PREVENT THE
COLUMN FROM COMPRESSING WITH IMPACT
(FRONT-END COLLISION). ALL FASTENERS USED
FOR ASSEMBLY MUST BE TIGHTENED WITH THE
CORRECT TORQUE. THIS WILL ENSURE THE COL-
UMN WILL BREAKAWAY WITH IMPACT.
CAUTION: Apply chassis lubricant to all the bear-
ing, thrust and friction producing mating surfaces
before assembly.
COLUMN SHIFT ASSEMBLY
(1) Insert the lock sector through the key/lock cyl-
inder hole in the key/lock cylinder housing. Install
the lock sector on the lock sector shaft (Fig. 13). En-
sure that the lock sector turns freely after installa-
tion.
(2) Install the lock rack preload spring. The bowed
side of the spring must contact the lock rack when
the rack is installed.
(3) Assemble the lock bolt and the lock rack (Fig.
14).
(4) Install the assembled lock bolt and lock rack in
the key/lock cylinder housing (Fig. 15). Mate the lock
rack block tooth with the lock sector block tooth.
(5) Install the shift lever detent plate on the key/
lock cylinder housing (Fig. 16).

ing lower bearing the housing. Align the indentations
in the bearing shell with the projections on the hous-
ing jacket.
(9) Install the gear selector lever spring in the le-
ver housing.(10) Install the gear selector lever housing and
shroud on the upper end of the steering column
jacket. Rotate the housing and ensure that the bear-
ing is properly seated.
(11) Place the gear selector in the PARK position,
and the lock rack pulled downward. Position and cor-
rectly seat the key/lock cylinder housing on the steer-
ing column jacket. Install and tighten the four
attaching screws.
(12) Insert the shift tube in the lower end of the
steering column jacket. Rotate it until the shift tube
upper key slides into the gear selector housing key-
way.
COLUMN SHIFT FINAL ASSEMBLY
(1) To install ignition switch lock, turn the key to
the LOCK position and remove the key. This will
cause the buzzer operating lever to retract in the
key/lock cylinder. Now insert the key/lock cylinder
into the housing far enough to contact the drive shaft
(Fig. 17). Force it inward and move the ignition
switch actuator rod up and down to align the compo-
nents. When the components align, the key/lock cyl-
inder will move inward and lock in place.
(2) Install the key warning buzzer switch.
