SERVICE INFORMATION
The steering linkage consists of a pitman arm, drag
link, tie rod, and steering damper. Adjustment
sleeves are used on the tie rod and drag link for toe
and steering wheel alignment.
Refer to Group 2, Front Suspension and Axle for
additional information.The tie-rod end ball stud seals should be inspected
during all oil changes.
A damaged ball stud seal requires removal of the
seal. Inspect the tie-rod end ball stud at the throat
opening. Check for lubricant loss, contamination, ball
stud wear or corrosion. If these conditions exist, re-
place the tie-rod. A replacement seal can be installed
if lubricant is in good condition. Otherwise, a com-
plete replacement ball stud end should be installed.
Lubricate the tie-rod end with MOPARtMulti-Mile-
age Lubricant, or equivalent product.
Use Puller C-3894-A for tie rod removal. Fail-
ure to use this tool could damage the ball stud
and seal (Fig. 1).
TIE ROD
REMOVAL
(1) Remove the cotter pins and nuts at the steering
knuckles and drag link (Fig. 2). Remove the steering
damper from the tie rod.
(2) Loosen the ball studs with a puller tool to re-
move the tie rod.

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-
ALOG.

GENERAL INFORMATION
The airbag system is a standard equipment safety
device on XJ (Cherokee) models. It is designed to pro-
tect the driver from serious injury, caused by a fron-
tal impact of the vehicle. If the airbag module
assembly is defective and non-deployed, refer to
Chrysler Corporation current return list for proper
handling procedures.
ARMING/DISARMING MECHANISM
BEFORE SERVICING A COLUMN EQUIPPED
WITH AIR BAG, REFER TO GROUP 8M, ELEC-
TRICAL FOR PROPER AND SAFE PROCE-
DURES.
The steering wheel hub incorporates an airbag
Arming/Disarming mechanism and a specially de-
signed nut-blocker. The nut-blocker serves as a safety
to prevent removal of the airbag module until the
unit has been disarmed. A removable plastic cover
plug on the top, outer hub of the steering wheel al-
lows access to the arming screw.
When the airbag module is disarmed, the arming
screw extends upward from the steering wheel hub.
This will prevent installation of the plastic cover
plug. Also, the nut-blocker is retracted to allow ac-
cess to the two upper airbag module mounting nuts.
When the airbag module is armed, the plastic cover
plug will install flush with the outer surface of the
steering wheel hub. In addition, the nut-blocker will
prevent access to the two upper airbag module
mounting nuts.THE FASTENERS, SCREWS, AND BOLTS, ORIG-
INALLY USED FOR THE AIR BAG COMPONENTS,
HAVE SPECIAL COATINGS. THIS HARDWARE IS
SPECIFICALLY DESIGNED FOR THE AIR BAG
SYSTEM. THEY MUST NEVER BE REPLACED
WITH ANY SUBSTITUTES. REPLACE WITH THE
CORRECT FASTENERS PROVIDED IN THE SER-
VICE PACKAGE OR FASTENERS IN THE PARTS
BOOK.
The Acustar columns (Fig. 1) have been designed to
be serviced as an assembly; less wiring, switches,
shrouds, steering wheel, etc. Most steering column
components can be serviced without removing the
column from the vehicle. For additional information
on electrical components refer to Group 8, Electrical.
CAUTION: Bumping, jolting and hammering on the
steering column shaft must be avoided during all
service procedures.
CAUTION: Disconnect negative (ground) cable from
the battery before servicing any component on the
column.
Safety goggles should be worn at all times
when involved with steering column service.

viced as an assembly; less wiring, switches, shrouds,
steering wheel, etc. Also most steering column com-
ponents can be serviced without removing the col-
umn from the vehicle. For additional information on
electrical components refer to Group 8, Electrical.
IGNITION SWITCH SERVICE
TEST AND REPAIR
If the ignition switch effort seems to be excessive
due to binding. Follow the procedure outlined below
to determine the cause.
When service procedures are performed on the
Acustar steering column there are certain areas of
the column that can not be tampered with. If a prob-
lem related to these areas of the steering column are
detected. The entire steering column (less the remov-
able components) should be replaced see (Fig. 1 and
2).
