Removal Procedure
IMPORTANT: Sectioning should be performed
only in the recommended areas. Failure to do
so may compromise the structural integrity of
the vehicle.
1. Visually inspect and restore as much of the
damage as possible to factory specifications.
2. Remove the following:
• Fender
• Windshield
• Door
• Hinge pillar blocks
3. Determine sectioning locations. Section in
approved areas only (see Fig.␣ 1-1).
4. Mark locations and cut part through outer
panel only.
5. Locate factory welds and drill out, noting
number and locations of welds (Fig.␣ 1-2).
6. Locate and drill out spot welds on weather
strip retainer as necessary. It is not necessary
to remove complete retainer.
7. Remove outer panel.
8. Note placement and number of foam baffles
for new installation. If baffles are damaged,
replacement service parts are available.
IMPORTANT: Hinge pillar blocks must be
replaced if damaged.
9. Clean adhesive and sealer from hydroformed
reinforcement tube as necessary. Note
location for reinstallation.

1. Cut service part in corresponding locations to
fit original cut lines. Leave a gap of one-and-
one half times the metal thickness of
sectioning joint.
2. Create 100␣ mm (4␣ in) backing plate on rocker
panel from unused portion of service part
(Fig.␣ 1-3).

inner rail for backing plate.
4. Drill 8␣ mm (5/16␣ in) plug weld holes in service
