3. Support the sub-frame with your hand and line up the lower mounting tab with the hole in the bottom of the frame rail. Insert the saved bolt through the sub-frame tab and thread into the lower frame rail. Do not tighten the bolts at this time.
4. From under the vehicle, align the nut plate as shown and place it in the channel on the backside of the crossmember. Line up the nut plate holes with the crossmember and sub-frame. Attach the nut plate using the supplied M12 x 35 bolts and washers from inside the sub-frame. Do not tighten the bolts at this time.
5. Repeat steps 2-4 for the passenger side of the vehicle.

Insert the supplied M12 x 35 bolts and washers through the sub-frame, crossmember, and CJ side-frame bracket. Place washers over bolts and thread 2 M12 nuts onto bolt (Figure 15). Do not tighten at this time.

10. From under the vehicle, insert a nut plate into the back channel of the crossmember. Insert 2 of the supplied M12 x 35 bolts and washers through the CJ lower frame bracket, sub-frame, crossmember, and thread into the nut plate (Figure 16). Do not tighten bolts at this time.

17. Once both D-Rings have been loosely installed, inspect the bumper to make sure it is centered on the vehicle. Adjust as necessary by sliding the sub-frames left to right.

    • Tighten all of the bolts of the sub-frame using an 18mm socket and ratchet.
    • Tighten the lower frame mounting bolt.
    • Tighten all of the D-ring bolts using an 18mm socket.
      Note: If installing bumper onto a CJ, tighten the side-frame brackets’ M10x 100 bolts and nuts at this time.
