STEERING

DESCRIPTION

The

steering
system
consists

of

recirculating
ball

type

gear
box

and

parallelogram
linkage

These

systems
give
good

response
light
handling
and

utmost
durability
Moreover
the

steering
linkage
is

equipped
with
a
torsion

rubber

system
idler
arm
which

absorbs
shock
from
the

wheel

Check
the
lubricant
of

gear
box

every
10
000

km
6
000
miles
and

replenish
recommended
oil
as

required

The

steering
linkage
should
be

greased
up
with
wheel

bearing
grease
every
50
000
km
30
000
miles

All

necessary
service

procedures
for
the

steering
lock

system
are
described
in
the

UNDERBODY
GENERAL

SERVICE

INFORMATION

Since
each

underbody
component
directly
affects
the

overall

strength
of
the

body
it
is
essential
that

proper

welding
sealing
and
rust

proofing
techniques
be
observed

during
service

operations

Whenever
the

body
is

repaired
be

sure
to
provide
the

repaired
body
parts
with

rust

proof

In
the

case
of
a

rust

proofmg
critical

underbody

component
it
is
essential
that
a

good
quality
type
air

dry

primer
such
as
corrosion
resistant
zinc
chromate
be
used

Do

not
use
combination

type
primer
surfacers

ALIGNMENT
CHECKING

PROCEDURE

Misalignment
in
the

underbody
affects
the
front

fender
door
trunk
lid

and
window

alignments
and
also

the
tail

gate
and
rear

body

opening
alignments
in
the

case

of
a
station

wagon
or
van

Underbody
misalignment

particularly
affects

the

suspension
system
thereby
causing

various

problems
that
arise
from

suspension
misalignment

It
is
essential
that

underbody

components
be

aligned

within
the

specified
dimensions

given
in

Figures
BF
13
14

and
IS

In

the
event
of

collision
damage
it
is

important
that

underbody
a1ignrnent
be

thoroughly
checked
and
if

necessary
realigned
to
the

specified
dirnensions

There
are

many
tools
that

may
be

ernployed
to
correct

collision

damage
such

as
frame

straightening
machines

external

pulling
equipment
other
standard

Cross

checking

operations
are
used
to

To

measure
the

distance
between

any
two

reference

points
on
the

underbody
accurately
two

specifications

are

required
