ALIGNMENT CHECKING
An accurate method of determining the alignment of the
underbody uses a measuring tram gauge. The tram gauge
set used to perform the recommended measuring checks
must include a vertical pointer able to reach 457 mm (18
inches).
Two types of measurements can be made with a tram
gauge: direct point–to–point measurements and mea-
surements calculated on a horizontal plane (datum line)
parallel to the underbody. Point–to–point measurements
are generally taken on steering and suspension engine
compartment parts and simply require the vertical pointers
to be set equally.
For horizontal plane measurements, the vertical pointers
must be set as specified for each point to be measured.
Dimensions–to–gauge holes are measured to the center
of the holes and flush to the adjacent surface metal unless
otherwise specified. It is recommended that the diagonal
dimensions to the cross–body be checked on both sides
in order to verify the dimensional accuracy of the vehicle
underbody.
FLOOR PAN INSULATORS
The floor pan insulators have been designed for the higher
floor pan temperatures that result from the use of the cata-
lytic converter in the exhaust system. Therefore, when
servicing a vehicle, it is essential that any insulators that
may have been disturbed or removed be reinstalled in the
original sequence and location. Also, if an insulator needs
to be replaced, use only the insulation specified for that
location on the floor pan.
When servicing or replacing interior insulators, observe
the following instructions.
S Install the insulators in the original position and se-
quence. Butt the pieces together in order to avoid
gapping or overlapping.
S If it is necessary to replace an insulator, use only
the specified insulation.
S Use the original part to determine the amount of
replacement material required and as a template for
cutting and fitting the new piece to the floor pan.
S When installing the insulator, do not enlarge any
cutouts or holes that are used for the attachment of
interior parts such as the instrument panel or the
floor console.
S Route the cross–body harness for interior parts
over the floor pan insulators. Clip it in the original
location.
S Do not apply spray–on deadeners or trim adhesives
to the top of the floor pan at the area directly over
the catalytic converter or the muffler.

Any insulator service repair or replacement should be the
same thickness, size, and location as the original installa-
tion in the vehicle.
