The spot weld on HSS panels is harder than that of an ordi-
nary steel panel.
Therefore, when cutting spot welds on a HSS panel, use a
low speed high torque drill (1,000 to 1,200 rpm) to increase
drill bit durability and facilitate the operation.
2. Precautions in spot welding HSS
This work should be performed under standard working condi-
tions. Always note the following when spot welding HSS:
The electrode tip diameter must be sized properly according
to the metal thickness.
The panel surfaces must fit flush to each other, leaving no
gaps.
Follow the specifications for the proper welding pitch.

Rear fender hemming process
1. A wheel arch is to be installed and hemmed over left and right outer wheel house.
2. In order to hem the wheel arch, it is necessary to repair any damaged or defaced parts around outer
wheel house.
CAUTION:
Ensure that the area that is to be glued around outer wheelhouse is undamaged or defaced.
Procedure of the hemming process
Peel off old bonding material on the surface of outer wheelhouse
and clean thoroughly.
Peel off a primer coat in the specified area where new adhesive
is to be applied on rear fender (the replacing part).
Apply new adhesive to both specified areas of outer wheelhouse
and rear fender.
Attach rear fender to the body of the car, and weld the required
part except the hemming part.
Bend the welded part starting from the center of the wheel arch
gradually with a hammer and a dolly. (Also hem the end of the
flange.)
Hemming with a hammer is conducted to an approximate angle
of 80 degrees.
Starting from the center, hem the wheel arch gradually, using
slight back and forth motion with a hemming tool.
Seal up the area around the hemmed end of the flange. 3M automix panel bond 8115,
or any equivalents

Foam RepairNIS0028Z
During factory body assembly, foam insulators are installed in certain body panels and locations around the
vehicle. Use the following procedure(s) to replace any factory-installed foam insulators.
URETHANE FOAM APPLICATIONS
Use commercially available spray foam for sealant (foam material) repair of material used on vehicle. Read
instructions on product for fill procedures.
1. Fill procedures after installation of service part.
–Remove foam material remaining on vehicle side.
–Clean area in which foam was removed.
–Install service part.
–Insert nozzle into hole near fill area and fill foam material or fill in enough to close gap with the service
part.
2. Fill procedures before installation of service part.
–Remove foam material remaining on vehicle side.
–Clean area in which foam was removed.
–Fill foam material on wheelhouse outer side.
NOTE:
Fill in enough to close gap with service part while avoiding
flange area.
–Install service part.
NOTE:
Refer to label for information on working times.

DESCRIPTION
This section is prepared for technicians who have attained a high level of skill and experience in repairing col-
lision-damaged vehicles and also use modern service tools and equipment. Persons unfamiliar with body
repair techniques should not attempt to repair collision-damaged vehicles by using this section.
Technicians are also encouraged to read Body Repair Manual (Fundamentals) in order to ensure that the orig-
inal functions and quality of the vehicle can be maintained. The Body Repair Manual (Fundamentals) contains
additional information, including cautions and warning, that are not including in this manual. Technicians
should refer to both manuals to ensure proper repairs.
Please note that these information are prepared for worldwide usage, and as such, certain procedures might
not apply in some regions or countries.

CAUTION:
A steel plate using ultra high strength steel plate is below welding with strength falling by adding heat,
and not doing a limit patch.
Front pillar butt joint can be determined anywhere within shaded
area as shown in the figure. The best location for the butt joint is
at position A due to the construction of the vehicle. Refer to the
front pillar section.
Determine cutting position and record distance from the locating
indent. Use this distance when cutting the service part. Cut outer
front pillar over 60 mm above inner front pillar cut position.
Prepare a cutting jig to make outer pillar easier to cut. Also, this
will permit service part to be accurately cut at joint position.
An example of cutting operation using a cutting jig is as follows.
1. Mark cutting lines.
A: Cut position of outer pillar
B: Cut position of inner pillar
2. Align cutting line with notch on jig. Clamp jig to pillar.
3. Cut outer pillar along groove of jig. (At position A)
4. Remove jig and cut remaining portions.
5. Cut inner pillar at position B in same manner.
