corresponding holes to be drilled into the

bottom edge of the Jeep’s crash bar. Look

through the holes to ensure that the Sub-

Frame Bracket does not interfere with any

of the hole locations. If it does, the bracket

can be adjusted slightly in either direction

because you had left the nuts un-tightened in

Step 16. Use a hammer and a 15/32” transfer

punch through each of the countersunk

holes to mark the five drill locations along the

bottom of the crash bar. Once these marks

have been made, remove the skid plate.

holes along the bottom of the crash bar that

were located and marked in the preceding

step.

De-burr the edges of the holes then use

touch-up paint or clear coat to protect the

bare metal.

20. Re-install the skid plate with the 3/8-16 X 1

SS flat head cap screws. The seven screws

which locate along the front surface of the

skid plate will thread into pre-existing weld

nuts.

FIGURE 20

For the five screws that install along the

bottom edge of the skid plate, use a 3/8 flat

washer and 3/8-16 lock nut on the inside

of the crash bar where the screw threads

protrude. Torque all 11 flat head cap screws

to 30 ft.-lbs.

21. Tighten the three 1/2-20 lock nuts at the top

of the Sub-Frame Bracket and torque them

to 70 ft.-lbs.

22. Torque the eight (8) bumper mount lock

nuts (two inboard and two outboard of each

frame rail) to 70 ft.-lbs.
