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

Misalignment
in
the

underbody
affects
the
front

fender

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

as
