Liftgate can be severely damaged by connecting electric welder ground lead to the
wrong place. To prevent damage, always connect ground lead directly to compo-
nent being welded and as close as possible to the weld.
NOTE: Lower mounts are essential for Liftgate to be installed correctly. They attach to the
truck frame and support the bottom of Liftgate.
1. Unbolt bracket plates from bottom of
main frame housing (FIG. 34-1).
2. Position 2 bolt-on mounting angles,
nearest to truck frame at bottom of Lift-
gate main frame housing (FIG. 34-2).
Then bolt each angle to hole allowing
closest fi t to truck frame.
3. Position 2 bracket plates (Kit items) on
truck frame at bottom of Liftgate main
frame housing (FIG. 34-2). Bolt to truck
frame. If necessary, modify bracket
plates for best fi t.
4. Clamp 2 short angles (no holes) (Kit
items) to bracket plates on truck frame
(FIG. 34-2). Position the 2 angles to
reach the angles bolted on bottom of
main frame housing.
5. With angles, and bracket plates
positioned and clamped together,
tack weld the angles and plates in
position (FIG. 34-2).
6. Unbolt tack-welded lower brackets
from truck frame (FIG. 34-2). Then,
fi nish weld the bracket plates and
angles.
7. Bolt the fi nish-welded bracket plates
and angles back in position on the
bottom of the main frame housing and
truck frame (FIG. 34-2).
