INSTALLATION
CAUTION
Do not use an impact wrench to tighten the bolt
of special tool spring compressor body
(MB991237). It will break the special tool.
1. Use following special tools to compress the coil
spring, and install the rear suspension coil spring
to the spring lower pad.
•MB991237: Spring Compressor Body
•MB991239: Arm Set
2. The rear suspension coil spring lower end must
be positioned as illustrated.
>>C<< REAR SUSPENSION SPRING
UPPER PAD INSTALLATION
Align the stepped section of the spring upper pad
with the upper end of the coil spring, and install the
spring upper pad.
>>D<< REAR SHOCK ABSORBER
INSULATOR INSTALLATION
Install the rear shock absorber insulator so that the
axis of the lower bushing inner pipe of the shock
absorber and the line between the rear shock
absorber insulator mounting bolts are straight when
looking from above.
>>E<< REAR SUSPENSION COIL SPRING
NUT (SELF-LOCKING NUT)
INSTALLATION
1. Temporarily tighten the rear suspension coil
spring nut (self-locking nut).
CAUTION
Do not use an impact wrench to tighten the rear
suspension coil spring nut (self-locking nut),
otherwise the piston rod locking nut inside the
shock absorber will be damaged.
2. Remove the special tools (MB991237,
MB991239), and then tighten the rear suspension
coil spring nut (self-locking nut) to 25 ± 5 N⋅m.

Power steering has been adopted in all vehicles to
make the steering system easier to handle.
FEATURES
•A 4-spoke steering wheel is used.
•MOMO leather-wrapped 3-spoke steering wheel
is used.
•A steering column has a shock absorbing
mechanism and a tilt steering mechanism.•Integral-type rack and pinion gear with high
rigidity and excellent response is used.
•A vane type pump with a fluid flow rate control
system which change steering effort according to
the engine speed is used.
•The separate plastic resin oil reservoir is used to
reduce weight and to make the fluid level
checking easier.
