11. Reinstall the RockBrawler™ II bumper

using the OE hardware in the two original bolt

locations on the sides of the frame rail, and a

supplied 3/8-16 X 1 Gr8 Hex Head Cap Screw

with 3/8 Flat Washer in each of the new bolt

locations on the outside of the frame rails.

Note that both the bumper’s mount flanges

are inserted between the outside of the frame

rail and the sway bar bracket.

12. Insert the 1/2-13X4-1/4 Gr8 Hex Head Cap

Screws into the two outside holes along the

underside of the bumper, with a 1/2 Gr8 Flat

Washer under the bolt head. Insert the bolt

up through the holes in the bumper and both

top and bottom surfaces of the crossmember.

Secure them with a 1/2-13 Gr8 Nylon Insert

Lock Nut and 1/2 Gr8 Flat Washer, where they

protrude through the top of the crossmember.

You may have to do this by feel, as the nuts

and washers will be threaded on inside the

bumper shell,

13. If the optional 2-1/2” LED backup lamps

were purchased, use the provided rubber

grommets to mount them into the recessed

mounting flanges inside the backup lamp

buckets. Use the electrical pigtails that

came with the lamps, along with wire and

connectors (not included) to wire the backup

lamps in to your Jeep’s backup lamp circuit.

14. Use the OE Spare Tire Mount hardware

to attach the Tailgate Plate to the tailgate.

The TailGate Plate must be oriented so the

welded-on brackets are toward the top and

driver side.

15. Wearing latex or nitrile gloves, “Pack” the

two tapered roller bearings with a quality

wheel bearing grease by hand or with a

bearing packing tool. The two matching

bearing races are already pressed in to the

tire carrier hinge housing.

16. Wearing a latex or nitrile glove, use your

fingers to apply a light sheen of grease to the

bare metal surfaces of the inside of the tire

carrier hinge housing and bearing races, as

well as the hinge spindle on the bumper (do

not coat the threads for the spindle nut). This

will help discourage rust formation on these

bare metal surfaces.

17. Insert a Tapered Roller Bearing into the

pre-installed Lower Race, inside the Hinge

Housing. Ensure that it seats correctly and

“feels right” in the race. Excess grease may

hold it in place temporarily, but it may be

helpful to turn the tire carrier upside down

until the next step is completed.

18. Use a bearing seal driver tool to carefully

install the grease seal into the bottom of the

hinge housing. If the proper tool is not available,

the step may be performed by carefully using

a large socket of the approximate diameter

of the seal and a soft dead-blow hammer to

work the seal into its seat. Be very careful

to drive the seal in evenly, do not let it get

misaligned while driving it in.

19. Install the Tire Carrier onto the bumper,

carefully guiding the hinge housing down

over the hinge spindle. Be careful not to

damage the grease seal when lowering the

tire carrier on to the spindle. There is a very

tight-tolerance slip-fit between inner diameter

of the tapered roller bearing and its seating

surface on the spindle. Be careful not to

let the bearing get misaligned as you lower

the carrier onto the bumper. Have a friend

support the opposite end of the tire carrier

during this and the next two steps.
