collision-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

original 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. Techni-

• 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 (2.36 in) 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.

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.

• 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.
