WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING
•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
paassenger (from rendering the SRS inoperative).
•Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.
•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 air bag control unit, SRS warning light, front impact sensors, air bag module,

FRONT WHEEL ALIGNMENT CHECK AND
ADJUSTMENT
M1331000900682
Measure wheel alignment with alignment equipment
on a level surface. The front suspension, steering
system, wheels, and tyres should be serviced to
normal condition before measuring wheel alignment.
TOE-IN
Standard value:
at the centre of tyre tread: 1 ± 2 mm
Toe angle (per wheel): 0°03' ± 06'
1. Adjust the toe-in by undoing the clip and lock nut,
and turning the left and right tie rod turnbuckles by
the same amount (in opposite directions). MB990883 Rear suspension bushing

NOTE: The toe will move out as the left
turnbuckle is turned toward the front of the vehicle
and the right turnbuckle is turned toward the rear
of the vehicle.
2. Install the clip and tighten the lock nut to the
specified torque.
Tightening torque: 40 ± 5 N⋅m
3. Confirm that the toe-in is at the standard value.
4. Use a turning radius gauge to check that the
steering angle is at the standard value.
STEERING ANGLE
Standard value:
TOE-OUT ANGLE ON TURNS
To check the steering linkage, especially after the
vehicle has been involved in an accident or if an
accident is presumed, it is advisable to check the
toe-out angle on turns in addition to the wheel
alignment.
Conduct this test on the left turn as well as on the
right turn.
Standard value:
CAMBER, CASTER AND KINGPIN
INCLINATION
Standard value:NOTE: *: difference between right and left wheels
must be less than 30'
NOTE: Camber and caster are preset at the factory
and cannot be adjusted.
CAUTION
Never subject the wheel bearings to the vehicle
load when the driveshaft nuts are loosened.
NOTE:
For vehicles with aluminium wheels, attach the
camber/caster/kingpin gauge to the driveshaft by
using special tool wheel alignment gauge attachment
(MB991004). Tighten the special tool to the same
torque 245
± 29 N⋅m as the driveshaft nut.
LOWER ARM BALL JOINT AXIAL PLAY
CHECK
M1332011300074
1. Raise the vehicle.
2. Remove the stabilizer link from the lower arm.
3. Move the lower arm up and down with your hands
to check for an excessive play in the axial
direction of the ball joint. If there is an excessive
play, replace the lower arm assembly.
LOWER ARM BALL JOINT COVER
CHECK
M1332008600321
1. Press the lower arm ball joint cover with your
finger to check that there are no cracks or
damage in the lower arm ball joint cover.
2. If the lower arm ball joint cover is cracked or
damaged, replace the lower arm assembly.
NOTE: If the lower arm ball joint cover is cracked
or damaged, it is possible that there may also be
damage to the ball joint. Inner

INSTALLATION
1. Ensure that the bearing is seated correctly.
CAUTION
Do not use an impact wrench to tighten the bolt
of special tool spring compressor body
(MB991237), otherwise the special tool will break.
2. Install following special tools to the strut assembly
same as its removal.
•MB991237: Spring Compressor Body
•MB991238: Arm Set
3. While the coil spring is being compressed by the
special tools, temporarily tighten the strut nut
(self-locking nut).
4. Align the hole in the strut spring lower seat with
the hole in the spring upper seat.
NOTE:
Using a rod as shown facilitates the alignment.5. Align lower end of the coil spring with the groove
in the spring lower seat, and then loosen the
special tools.CAUTION
Do not use an impact wrench to tighten the
self-locking nut, otherwise the strut nut
(self-locking nut) will be damaged.
6. Using following special tools, tighten the strut nut
(self-locking nut) to 60 ± 10 N⋅m.
