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.
