29. Measure the overall height of your spare tire (NOT one of the mounted tires on your Jeep!), divide that measurement in half, then add one inch. The resulting number will be your tire mount height measurement. With the Tire Carrier closed and latched, measure upward from the recessed step surface of the bumper, and make a small mark on the tire carrier at the tire mount height measurement.
30. Use (4) 7/16-18 x 1 Gr8 Hex Head Cap Screws with (4) 7/16 Flat Washers and (4) 7/16-18 Nylon Insert Lock Nuts to attach the Tire Mount - Carrier Side to the Tire Carrier, centered on the mark you made in the previous step. The slots in the tire carrier allow for some adjustment, however if there isn’t enough adjustment to center the Tire Mount exactly centered on your mark, move it up slightly to the next set of slotted holes in the carrier.
31. Hold the Tire Mount - Tire Side up against the back side of your spare tire, with the short end of the square tube protruding through the hole in the wheel. Visually align the holes in the mounting plate with at least three holes in the wheel, while keeping the mounting plate centered. There are more than three holes in the mounting plate, to allow for a variety of wheel lug patterns to be used. Once three holes are correctly aligned, mark them with a felt-tip marker.
32. Use a shop press or hammer to drive the three provided Wheel Studs into the mounting plate. Make sure the studs point away from the long section of square tube (with the slotted hole).
33. Fit the Tire Mount - Tire Side channel on to the corresponding beam of the Tire Mount - Carrier Side. Use (2) 7/16-18 X 3 Gr8 Hex Head Cap Screws with (4) 7/16 Flat Washers and (2) 7/16-18 Nylon Insert Lock Nuts to secure the Tire Mount-Tire Side to the Tire Mount - Carrier Side, using the slotted holes provided. Leave these fasteners loose at this time.
34. With the help of a friend, lift the spare tire onto the Tire Mount - Tire Side, and fit the previously installed lug studs through the holes in the wheel. Loosely thread the (3) Lug Nuts on to the studs, holding the tire on. Leave the Lug Nuts threaded on only about half way.
35. Push the Tire Mount - Tire Side inward toward the Tire Mount -Carrier Side, and fully tighten the two 7/16-18 cap screws and nuts that were installed in the previous step.
36. Finish tightening the (3) Lug Nuts. This will draw the sides of the tire tightly against the frame of the Tire Carrier, to prevent rattles and squeaks.
37. Use (4) 1/4-20 X 3/4 SS Button Head Cap Screws, (4) 1/4 Flat Washers and (4) 1/4-20 Nylon Insert Lock Nuts to fasten your license plate to the License Plate Mount.
38. Use the 1/4-20 X 3/4 Hex Head Cap Screws with 1/4 Flat Washer and 1/4-20 Wing Nut to fasten the License Plate Mount to the Tire Mount at the center of the spare tire. Note that you will need to keep these wrenches available in the vehicle in order to remove the license plate mount to access your spare tire in the future.
39. Once the entire bumper is mounted and tested for proper operation, remove and disassemble the bumper for paint or powder coat. If painting yourself, careful preparation will make a big difference in the quality and longevity of your paint job, even using “rattle can” aerosol paints. Begin by thoroughly cleaning the bumper with solvent or de-greaser, then make sure all residue is removed. Even if you use cheap paint, try to use a good quality primer. “Etching” primers are best to use on bare, unpainted metal. Allow it to properly dry before painting, and between paint coats. Note that the Spyder Web Gusset Detail is detachable so that it may be painted or powder coated a contrasting color from the rest of the bumper.
If powder coating, make sure the entire bumper and tire carrier are completely disassembled first. Make sure the bearings, races and grease seal are not yet installed. Make sure your powdercoater understands that the hinge spindle must be masked off (not coated).
40. Once the bumper has been painted or powder coated, re-install by repeating the above steps.
