Check that you have all of the parts and hardware shown before starting.

Lay out the parts and learn the names: MJDIY01 center section, two MJDIY02 wings, two MJDIY03 side caps, MJDIY04 and MJDIY05 mounts, MJDIY06 hitch support, and the D ring tabs. Test fit before painting, and keep paint and bed liner off all threads.

Clamp the center section (MJDIY01) to a table and make three bends: 90 degrees, then 40 degrees, then 50 degrees, re clamping between each bend.

Bend the two wings (MJDIY02) the same way, making one left and one right so they end up as opposites.

Clamp each side cap (MJDIY03) in a vise or to a table and bend it to 15 degrees, making a left and a right.

Assemble the bumper mounts by seating the horizontal piece in the notch of the main mount, then tack each pair together and set them aside.

Lay the center section face down and tack the wings to it, then tack the side caps to the wings. Weld and grind the whole shell before adding the D ring tabs or mounts.

Insert the D-ring tabs through the bumper from the back so they stick out the back about 1/2 inch. Tack weld them on the inside of the bumper only, since the bumper mounts sit flush against the outside of the tabs.

Slide the bumper mounts into place. The notch in each mount fits around the D-ring tab. Tack weld the mounts, keeping them square with the center section.

Test fit the bumper on your Jeep now, before final welding and painting, in case adjustments are needed.

If you are not installing the front hitch, weld the precut slots in the center of the bumper closed and grind them flat. Without the receiver, the bumper is now complete.

For the optional hitch, cut out the perforated plug and set the receiver tube through the opening with about 1/4 inch sticking out. Tack one corner, square it to the bumper face, then tack the opposite corner. If you are not using the JCR hitch tube, you are responsible for cutting and drilling your own tube to fit.

Set the bumper face down and place the receiver reinforcement bracket over the receiver and against the bumper, then weld it in.

Once all welding and grinding is done and the test fit is good, paint or bed-line the bumper. Keep all coating off threads, and open up any holes the coating closes with a drill or file.

Support the factory rear bumper, remove the bolts holding it to the frame and take it off, keeping the factory hardware. Lift the new bumper into place, line the bumper mounts up with the factory frame mounting holes and start the factory bolts by hand. Center the bumper, then tighten all bolts to factory torque. Recheck the hardware after the first few drives.

Congratulations, you have completed the install of your new Comanche MJ DIY Rear Bumper! Enjoy your new product.
