a. Remove (2) M8 bolts connecting the center hitch tabs to the bumper and return to owner.

3. If present, remove (1) M14 bumper bracket bolt from each frame rail (completed in Step 2c). Raise hitch into position by aligning the rear most holes in the hitch with the holes where the bumper bracket bolts were removed. Secure hitch using M14 bolts and 9/16" conical toothed washers in existing weldnuts, as shown.

4. Install 1/2" carriage bolts, spacers, and flange nuts in remaining holes as shown.

5. Torque all 1/2" hardware to 110 ft-lbs. Torque all 14mm hardware to 103 ft-lbs.
