REAR

SUSPENSION

DESCRIPTION

Rear

suspension
consists
of
semi
elliptic

leaf

springs

telescopic
hydraulic
shock
absorbers
and
rubber

bumpers

The
rear

spring
center

pin
is

off
set
110
mm
4
33
in

toward
the
front
from

the
center
of
the

spring
This
is

done
to
reduce

spring
wind

up
and
to
decrease
the

arc

while
the
rear
wheel

swings
through
Thereby
minimizing

the

possibility
of
the
rear

suspension
effecting
vehicle

stability

Iso

clamp
devices
are
used
for

attaching
the

axle

housing
to
the

spring

The
leaf

springs
shock
absorbers
and
rear
axle

housing

are
mounted
on
rubber

bushings
at
each
end
to
minimize

noise
and
vibration
of
the
transmission
to
the
car

body

and

passenger
