BODY
pointer
used at the rearward location With the
proper
settings
the tram bar will be
on a
plane
parallel
to that of
the
body
The
exception
to this would be
when one of the
reference locations
is
included in the
misaligned
area
then
the
parallel
plane
between the
body
and the
tram
bar
may
not
prevail
After
completion
of the
repairs
the tram
gauge
should
be set at the
specified
dimension to check
the
accuracy
of the
repair operation
CAR PREPARATION
Preparing
the
car for the
underbody alignment checx
involves the
following
I
Place
the car
on a level surface
2 The
weight
of the car should be
supported
at
the
wheel locations
3 A
visual
damage
inspection
should be
made to
eliminate
unnecessary
measuring Obviously
damaged
or
misaligned
areas
may
often be located
visually
TRAMMING SEQUENCE
The
tramming sequence
will
vary
depending upon
the
nature and
location of
the
misaligned
area Prior to
perfonning any tramming
operation
the
accuracy
of
reference
points
to be used must be
determined
A
measurement that
originates
from
a
reference
point
included
in
a
damaged area will
produce
untrue
results
and confuse the evaluation
of
the
underbody
condition
Unlike the conventional
type
offrame
design
the unitized
type
of
body
construction
seldom
develops
the
condition
of diamond in the
floor
pan
area as a result of front or
rear end collision
Therefore
underbody alignment
checking
can
usually
originate
from
the
body
floor
pan
area
If
inspection
indicates
that
these
locations have been
disturbed
and are not suitable for
measuring
one
of
the
undamaged suspension
locations
should
be
used
as an
initial reference
pnint
If
a
rare
situation should
exist
where all of
these locations
are
not suitable
as reference
points repair operations
should
begin
with the
body
floor
pan
area
All other
underbody
components
should
be
aligned
progressively
from this
area
