DESCRIPTION

The
front

suspensIOn
IS
of
a
strut

type
The

shock
absorber
and

spIndle
are
combIned
to

a

Ingle
Unit
whIch

IS

supported
by
the

COIl

spnng
at
the

upper
end
and

by
the
transverse

lInk
at
the
lower
end

The

spIndle
IS
Installed

on
the
bottom
of
the

strut
outer

caSIng
by
means
of

weldIng

A
ball

JOInt
IS
attached
to
the
lower

part
of

the

spIndle
The
ball

JOInt
and
the
transverse

lInk
lower
lInk

are
connected
and

they
are

fitted
to
the

suspensIOn
member

through
a

rubber
b

shIng
The
shock
absorber

mechanism

IS
bUIlt
In
the
strut
outer

caSIng

A
COIl

sprIng
IS

apphed
between
the

upper

sprIng
seat
fitted
to
the

upper
end
of
the

piston
rod
and

spring
seat
welded
to
the
outer

caSIng
These

components
assembled
to

a

SIngle
umt

are
fitted
to
the
chaSSIS
frame
at

their

upper
part
through
the
thrust

beanng

M
eover

the
1ransverse
hnk

supports
the

84
overall
forward
and
backward
strut

movements

by
means
of
the

tensIOn
rod
fitted

to
the

cha
sls
frame

through
a
rubber

bushIng
The
rubber

bushIng
adopts
a

non
lInear

shape
WIth
whICh
the
forward
and

rearward

ngldltles
are

changed
The
tor

slOn
bar

type
stabilIzer

adopted
In
thiS

suspensIOn
system
IS
used

so
that
the
strut

maIntaInS
connectIOn
between
both
Side

struts

Thus
thiS

suspensIOn
mechanism
absorbs

shocks
toward
all
directIOns
Into
the
chaSSIS

effectively
and

effiCIently
the
tensIOn
rod
ab

sorbs
forward
and
backward
shocks
the
strut

absorbs
vertical
shock
and
the
transver

se
lInk
absorbs
shock

applIed
toward

SIdeway

RECOMMENDATIONS

Due
to
the
need
for
a

large
number
of

speCial

tools
and

ahgnment
eqUIpment
It
IS
recom

mended
that
