WCAUTION:
VI When fasteners are removed, always reinstall them at the same location from which they were removed. If a
fastener needs to be
replaced, use the correct part number fastener for that application. If the correct part
number fastener is
not available, a fastener of equal size and strength (or stronger) may be used. Fasteners
that are
not reused, and those requiring thread locking compound, will be called out. The correct torque
value must be used when installing fasteners that require it. If the above conditions are not followed, parts or
system damage could result.

30-2 REAR SUSPENSION
GENERAL DESCRIPTION
The rear suspension is a 4-link, coil spring type
suspension
with a stabilizer bar, consisting of two
trailing links, center link, lateral rod, shock absorber,
and
stabilizer. In this suspension, the links are specially
arranged to enable the rear axle to move freely,
thereby expanding suspension stroke, reducing
friction, and improving
lateral rigidity and roll control.
All
these result in improved stability, riding comfort,
and rough road
maneuverability.
Each link connects the axle housing with the frame
through a runner bushing. The
axle housing is
supported
by the trailing links and center link
longitudinally
and by the lateral rod latitudinally.

E) REMOVAL
Preparation: • Turn the steering wheel so that the
vehicle's wheels are pointing straight
ahead.
W CAUTION: •
Turn the ignition switch to "LOCK".
•
Disconnect the battery "-" terminal
cable, and wait at least 5 minutes.
• Disconnect the yellow 3way SRS
connector located under the steering
column.
The wheels ofthe vehicle must be straight ahead
and
the steering column in the "LOCK" position
before disconnecting the steering wheel. Failure
to do so will cause the coil assembly to become
uncentered
which will cause damage to the coil
assembly.
1.
Front console assembly
•
Remove the transmission (for M{f) and
transfer control lever knob.
• Disconnect the wiring harness connectors.
2. Steering lower cover
• Remove the engine hood opening lever.
3. SRS module (Fig.3F4-14 and 15)
• Loosen the inflator module fixing bolt from behind
the steering
wheel assembly using a TORxe driver
or
equivalent until the inflator module can be
released from steering assembly.
•
Disconnect the yellow 2way SRS connector
located behind the inflator module.

W WARNING
THE INFLATOR MODULE SHOULD ALWAYS BE
CARRIED WITH THE URETHANE COVER AWAY
FROM YOUR BODY AND SHOULD ALWAYS BE
LAID ON A FLAT SURFACE WITH THE URE­
THANE SIDE UP. THIS IS NECESSARY BE­
CAUSE A FREE SPACE IS PROVIDED TO ALLOW
THE AIR CUSHION TO EXPAND IN THE UN­
LIKELY EVENT
OF ACCIDENTAL DEPLOYMENT.
OTHERWISE, PERSONAL INJURY MAY RESULT
(FIG. 3F4-16).

4. Steering wheel
•
Apply a setting mark across the steering
wheel and shaft so parts can be reassembled
in
their original position (Fig. 3F4-17)
• Use special tool. Remove the steering wheel.
Move the tires
to the straight ahead position
before removing the steering wheel (Fig.
3F4-
18).

\V CAUTION:
Never apply force to the steering wheel in
direction
of the shaft by using a hammer or other
impact
tools in an attempt to remove the steering
wheel. The steering shaft is designed as an

When turning the SRS coil clockwise to full, stop
turning if resistance is felt. Forced further turning
may damage to the cable in the SRS coil.
5. Steering column cover
• When installing the steering column cover, be
sure
to wire (through each harness) as
illustrated so that the harnesses starter
