Rear Bumper with Tire Carrier

GARD Pro Not Registered

By: cbbr




My rear bumper is 2×4 and 2×2 3/16 with 10 guage sheet metal. The tire carrier is 2×4 3/16 held on with a 1″ x 10″ grade 8. The bolt has 2 contact points and passes through 4 sections of the 3/16. There is a grade 8 nut welded in near the bottom. I also ran a seam down the path so that the bolt threads all the way down and used flanged bronze bushings to keep things smooth. The other side is a 9/16 grade 8 and another nut welded in.

The sides of the rear are 3/16″ square tube, capped and angled in the front and then skinned in the 10 gauge sheet metal. They follow the original rub strip.

The whole thing is mounted to a set of CUCV mounts with lots of 9/16″ grade 8′s and has CUCV clevis rings.

The gas cans are NATO 5 gals and the mount is 3/16″ angle iron. I boxed in an original Chevy license plate mount so thatI could retain the light for inspection purposes.
I custom made the hinge with 2 shear points after seeing and reading about tire carriers using the aftermarket hinges breaking.  I believe that my design is far stronger because of both materials and the double shear point.

Step 1 would be determining how long it needs to be. Measure carefully write it down. carefully measure the one you cant to shorten. measure it extended and retracted. Next decide if during its intended range of motion it extends more than it retracts or the other way and come up with a measurement of how much you want to remove.

After looking my driveshaft over I decided to trim off of the fixed yoke end.

I ground the weld flush and I could just make out the parting line

Using a zipcut I grind in about 1/8″ until I can see a parting line. You don’t need to go deep.

Make a mark on the tube how far you want to cut it. In my case 4″

I used a piece of emery cloth as a wraparound to get a straight cut line.

Start cutting (zipcut) Go slow, take your time. It matters.

Here is one of those great tricks! add around a cup of ATF to the inside of the tube before you put it together. It prevents rust and helps to balance the shaft and/or dampen the vibrations.
