Removal Procedure
Important:
• | Check front of dash panel, floor panels, and all other SMC for
cracks or areas that may need to be repaired or resealed. |
• | This procedure is used when damage to the frame rail is limited
to the portion rearward of the seat back area. |
Important: Save any and all brackets, mounting studs, and accessories for re-use
as necessary.
- The seat back sectioning area is exposed by modifying or removing
close-out panels and tunnel braces to access to all sides of the rail. There
are some high strength steel panels located in the rear of the vehicle
which can be repaired if damage excludes kinks, or damage which would
require the use of heat to straighten.
Remove related panels and components, including rear compartment panel.
- Remove the fuel tank from the damaged side of the vehicle.
- Remove the outer lock pillar extension panel in order to access
the rail.
- Apply a piece of 25 mm
(1 in) tape along the lock pillar.
- Cut to create a weld flange
for installing the new extension panel (1).
Caution: Sound deadener foam in the lock pillar can be a fire hazard. Avoid welding
to the lock striker pillar.
- Using a die grinder, cut along the edge of tape line.
- Cut stitch welds along the rail and drill out the resistance welds
along the tunnel brace.
- Remove lock pillar extension panel.
- Loosen and pry up the
upper extension panel (1) for the fuel tank for access to the rest of the
rail for sectioning. Remove for replacement if damaged.
- Using a die grinder, cut through the stitch welds that attach
the tunnel brace to the frame rail. Make cuts favoring the rail side of the
welds.
- Determine the location to perform the sectioning; be sure to stay
within the recommended areas.
- Cut the damaged rail accordingly.
- Remove the damaged rail portion.
- Clean and prepare all surfaces for assembly as necessary.
- Perform offset lap-joint sectioning as required.
Installation Procedure
- Stitch weld the tunnel brace to the frame rail, duplicating the
factory welds.
- Attach upper extension panel.
- Weld the upper extension panel, duplicating factory welds as much
as possible. It may be necessary to replace extension panel if heat is required
to straighten.
- Trim new lock pillar extension panel to fit properly.
- Drill 8 mm (5/16 in)
holes for plug welding along the edge which will overlap the flange created
during removal.
Install lock pillar extension in factory location and plug weld to original
extension flange and to tunnel brace.
- Stitch weld lower edge in factory locations to the frame rail.
- Apply anti-corrosion materials to all inner surfaces as necessary.
• | Do not combine paint systems. |
• | Refer to paint manufacturer's recommendations. |
- After sectioning repairs are completed, attach panels and components
as necessary.
