FRONT SUSPENSION – STRUT ASSEMBLY33A3
CAUTION
(1) To compress the coil spring securely, ensure that the
special tool is extended as far as the spring will allow,
then fitted evenly to the coil spring.
(2)There is a danger of special tool damage, so do not use
an impact wrench.
2. Using the following special tools, release the selflocking nut.
• Special spanner (MB991367)
• Pin (MB991385)
CAUTION
There is a danger of the lock nut inside the strut piston rodworking loose, so when loosening the selflocking nut, do
not use an impact wrench.
Important note on assembly
Fitting selflocking nut
1. With the coil spring compressed with the special tool,
temporarily tighten the selflocking nut.
2. Match up strut assembly hole in lower spring seat, and hole in
upper spring seat.
Remarks
Using a lever to align the holes can make this job easier.
3. Match both tips of coil spring precisely with the slots on the
spring seats, and release the special tool.
4. Using the special tool, tighten the selflocking nut to the
specified torque.
Tightening tor
que: 60 ± 10N·m
CAUTION
There is a danger of the lock nut inside the strut piston rod
working loose, so when loosening the selflocking nut, do
not use an impact wrench.

Cautionary Note regarding servicing of vehicles fitted with SRS airbags and/or seatbelts with
pre-tensioner systems.
Warnings:
1. Incorrect inspection or servicing of a component part of the SRS airbag system or seatbelt pre-tensioner system, or
a part relating to these systems, may cause accidental operation (deployment) of the SRS airbag or seatbelt pre-
tensioners, or may cause these systems to be disabled, leading in either case the risk of serious injury.
2. If parts may be affected by heat during painting operations, then those parts must be removed in advance. This
applies to the SRS-ECU, airbag modules (driver’s sear and front passenger’s seat), clock springs, front impact
sensors, side impact sensors, and pre-tensioner seatbelts.
• 93ºC or above : SRS-ECU, airbag modules (driver’s sear and front passenger’s seat), clock springs, front impact
sensors, side impact sensors
• 90ºC or above : Pre-tensioner seatbelts
3. The component parts of the SRS airbag system or seatbelt pre-tensioner system, and parts relating to these
systems, must always be inspected and serviced by a Mitsubishi dealer.
4. Service personnel must read the relevant service manuals (particularly, Section 52B – SRS Airbags) carefully and
thoroughly, before inspecting or servicing the component parts of the SRS airbag system or seatbelt pre-tensioner
system, and parts relating to these systems.
