REMOVAL AND INSTALLATION
Caution
1. Before removing the steering wheel and air bag module assembly, always refer to GROUP
52B - Service Precautions, Air bag Module and Clock Spring. Also, set the front wheels so
that they are facing straight forward, and remove the ignition key. If you fail to do this, the
SRS clock spring will be damaged, causing the SRS air bag to be inoperative and serious
injury.
2. *
1: Indicates parts which should be initially tightened, and then fully tightened after placing
the vehicle horizontally and loading the full weight of the engine on the vehicle body.
3. *
2: Indicates parts which should be temporarily tightened, and then fully tightened with the
vehicle on the ground in the unladen condition.
Caution
If the vehicle is equipped the Brembo disc brake, during maintenance, take care not to contact
the parts or tools to the caliper because the paint of caliper will be scratched.

Caution
1. To prevent the ball joint thread from damage, the tie
rod end mounting nut must be only loosened but not
removed from the ball joint. Be sure to use the special
tool.
2. Support the special tool with a cord to prevent it from
coming off.
AB"FIXTURE/BUSHING/STABILIZER BAR REMOVAL
Carry out the following operations to ensure working space
in order to remove the fixture, the bushing and the stabilizer
bar.
1. Use a transmission jack to hold the crossmember, and
then remove the crossmember mounting nuts and bolts.
2. Lower the crossmember until the fixture, the bushing and
the stabilizer bar can be removed.
Caution
Be careful not to lower the crossmember excessively,
otherwise the power steering return hose bracket may
deform.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger (from rendering
the SRS inoperative).
(2) Service or maintenance of any SRS component or SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3) MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any SRS-related
component.
NOTE
The SRS includes the following components: SRS-ECU, SRS warning lamp, air bag module, clock spring and interconnecting
wiring. Other SRS-related components (that may have to be removed/installed in connection with SRS service or maintenance) are
indicated in the table of contents by an asterisk (*).
