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.

STEERING RHD
GENERAL SERVICE PROCEDURE INFORMATION
Right hand drive service procedures and torque
specifications involving steering; linkage, gear and
column are the same as left hand drive vehicles ex-
cept where shown. Refer to appropriate service pro-
cedures regarding each component in the system.
The steering linkage consists of a pitman arm, drag
link, and tie rod. Adjustment sleeves are used on the
tie rod and drag link for toe and steering wheel
alignment (Fig. 1).
RECIRCULATING-BALL POWER STEERING GEARS
The steering gears can be adjusted and internally
serviced. The components CANNOT be interchanged
with those of a left hand drive vehicle.
The steering gear has a 17.5:1 ratio.
POWER STEERING PUMP
PRESSURE AND RETURN LINE
REPLACEMENT
Cap hose open ends and pump/steering gear fit-
tings to prevent entry of foreign material.
WARNING: POWER STEERING FLUID (AND PUMP
COMPONENTS) AND THE EXHAUST SYSTEM CAN
BE EXTREMELY HOT IF THE ENGINE HAS BEEN
RECENTLY OPERATING. DO NOT START THE EN-
GINE WITH ANY LOOSE OR DISCONNECTED
HOSES. DO NOT ALLOW THE LINES TO TOUCH A
HOT EXHAUST MANIFOLD.REMOVAL
(1) Place a drain pan under the pump and gear.
(2) Disconnect the pressure and return line from
the steering gear (Fig. 2, 3).
(3) Disconnect the pressure and return line from
the pump (Fig. 4). Drain the fluid from pump and
reservoir.

Fig. 2 Fluid Lines On Steering Gear
19 - 74 STEERINGJ

(4) Tighten fittings at pump and gear to 28 Nzm
(21 ft. lbs.) torque.
(5) After installation, add power steering fluid, in-
spect and test for fluid leaks.
PUMP REPLACEMENT
REMOVAL
(1) Remove and cap pressure and return lines from
pump. Refer to Pressure and Return Line Replace-
ment in this section.(2) Remove belt tension, turn tensioner clock-wise
and slip belt off pulley (Fig. 6).
(3) Remove the screws retaining front bracket and
pump to the rear bracket (Fig. 7, 8).
(4) Remove screws that attach the front bracket to
the rear bracket (Fig. 9).
(5) Remove pump from bracket.
To remove the rear bracket from engine, the air
conditioning compressor and bracket must be re-
moved first. Refer to Group 24, Heating and Air Con-
ditioning for removal procedures.
(6) Remove fan from pulley and hub on rear
bracket.
(7) Remove 4 screws attaching the rear bracket to
block (Fig. 10, 11).
(8) Remove bracket from engine.

INSTALLATION
(1) Install the rear bracket to engine. Install
screws finger tight.
(2) Tighten front screws to 48 Nzm (35 ft. lbs.)
torque. Tighten side screw to 48 Nzm (35 ft. lbs.)
torque. It is important to torque the front screws
FIRST and the side screw LAST. This will prevent
the bracket from twisting or distorting.
(3) Install fan to pulley and hub. Tighten the nuts
to 27 Nzm (20 ft. lbs.) torque.
(4) Install air conditioning bracket and compressor
to engine. Refer to Group 24, Heating and Air Condi-
tioning for installation procedures.(5) Loose assemble screws through front bracket,
pump and into rear bracket.
(6) Install screws that attach the front bracket to
the rear bracket (Fig. 8). Tighten the screws to 27
Nzm (20 ft. lbs.) torque (Fig. 7).
(7) Install belt, turn tensioner clockwise and slip
belt onto pulley (Fig. 6).
(8) Install pressure and return lines to pump. Re-
fer to Pressure and Return Line Replacement in this
section.
(9) After installation, add power steering fluid, in-
spect and test for fluid leaks. Refer to Power Steering
PumpÐInitial Operation.
