Lower Extension Panel to Access the Rail
Rail-Underbody Side Assembly
Important: The lower floorpan extension
panel is to be reinstalled two inches
forward of the SMC floorpan. This will
eliminate the potential to de-bond the
floorpan when re-installing the floorpan
extension panel (see Fig.␣ 3.24 below).

Using a die grinder, cut along the forward
edge of tape to create a 2” flange (Fig.␣
3.24). Cut stitch welds along the rail and drill
out the resistance welds along the tunnel
brace. Remove floorpan extension panel.
6
Determine the location to perform the
sectioning
(be sure to stay within the
recommended areas), and cut the damaged
rail accordingly. (
See Sleeved Butt-Joint
Method Repair Procedures)

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.
