17. Use an open end wrench to hold the coupler nut
stationary while turning the head of the bolt clockwise
with a ratchet (or small impact wrench) and socket. As
you turn the ratchet, the bolt will draw the far end of the
nut-sert toward the inside of the sheet metal, gripping it
with the knurled outside edge of the nut-sert as it deforms.
Continue to turn the ratchet until the nut-sert is fully seated.
DO NOT OVER-TIGHTEN as you can damage the nut-sert,
or cause it to lose its grip.
18. Once the nut-sert has seated correctly, loosen the
bolt then remove it and the rest of the tool from the nut-sert.
Install a new nut-sert onto the tool, oriented the same as
the last, and set it aside until your next nut-sert installation.
19. With the tool removed, inspect the nut-sert to
make sure it is properly seated and that the surrounding
sheet metal isn’t excessively deformed. Note that some
deformation of the sheet metal is normal, and that it will be
covered by the part after installation.
If you “spin” a nut-sert: That is, if it loses its grip due to
over-tightening or improper installation, the quickest,
easiest x is to use a MIG welder to place a small
tack weld at the edge of the nut-sert ange. Before
applying the tack weld, sand or grind the paint from a
very small area of the sheetmetal where the tack weld
will be. Then insert a screw into the nut-sert to protect
the threads from weld splatter. Only apply a very small
tack or two, as you do not want to heat up and deform
the nut-sert or the sheetmetal. Then grind the tack(s)
smooth and apply touch-up paint to prevent rust.
20. Re-Install the finished Trail Corners using the
supplied stainless steel button head hardware.
IMPORTANT! Do NOT over-tighten the button head
cap screws, as you may accidentally “spin” the Nut-
Sert if you over-tighten!
21. Repeat the previous steps for the remaining side.
22. If re-using the OE taillights and license plate mount,
reinstall them by reversing the removal procedures from
the beginning of these instructions.
