    GM 14 Bolt front and rear swap

    Whatís up everyone?

    So Iím on deployment currently and we have this old 1985 Chevy CUCV (basically military terms of a 3/4 or 1 ton long bed Silverado) Axles look to be in pretty good shape, so I decided I was going to bring them home. Currently have the rear axle out and beginning tear down and prepping. Iíve seen most writes use 14 bolts from a Ď99-Ď06 Silverado but I decided what the hell? Theyíre ďfreeĒ and it wills till cost way less to have them fabbed up and built than buying a brand new or even used set of dynatrac 60/60s. If it doesnít work out I wouldíve only waisted time and not money. End goal is 5.38s and ARB air lockers front a rear. So here we go! Pics of axles and donor truck.

    And before anyone points it out yes I realize the front axle is a passenger side drop where as my JKU is a driver side drop. Pretty sure I can make it work. It will take some extra fab work but should be aright in the end.

    This should be an interesting project. Iíll be following along. Whatís the width on that rear axle? The reason behind the later model being used is because itís wide enough to make room for the lower control arm mounts. Even on the wider axle itís a squeeze to get them in there. As for the front, what do you mean about taking some fab work due to the passenger drop? Assuming youíre planning to re-tube it? My guess is youíll have clearance issues with that massive center section up there. Planning to keep suspension type the same? Any idea what your plans are for tone rings yet?

    Hub end to hub end is around 71Ē off a quick tape measure check. Suspension I plan to keep what I have right now, which is a 6.5Ē BDS long arm kit. All suspension lift, no body lift. I seen a couple of build kits where you shave all the brackets off and then weld on a truss that has all brackets and mounts attached already but I think those are for the later year axles. Artec industries has a tone ring kit Iíve looked at. 60 tooth ring and brackets for ABS sensors as emergency brake cables. I would like to keep all the stock electronics intact if I can. Yea was planning on retubing or rather ďflippingĒ the tubes on the front and then shortening or lengthening from there. If I have to make the axles wider for brackets to fit Iím not too worried about that. I plan on moving back to Alaska after the military and they donít have fender laws. They only care about mud flaps to stop rocks from being flung into windshields. Donít have a measurement for the front as itís still under the donor truck but Iíll post that once I get it out. In all honesty the only reason behind even attempting this is because these axles are essentially free. I plan to keep my Jeep as my daily driver and donít necessarily need 1 tons under it. But if I can get them why not? Also this is going to be a huge learning process for me as this will be the first axle build Iíve ever done. Iím a mechanic in the army but we arenít allowed to disassemble things like this, weíre basically glorified parts changers and diagnosers.

    nice project. look into Crane Axle. they do a ton of 14 bolt stuff. you'll definitely want to shave the diffs for clearance. so you'll have to decide if you want to do something like a Crane 13 bolt which gives you an inch extra or do something like TMR 15 bolt shave which requires machining down the ring gear. that will give you more clearance but at the cost of custom ring gears. if you were to ever blow one up, it will take longer to get back on the road.

    Yeah should be a lot of fun. With a lot of head scratching Iím sure too. It will not be free though even though the axles were free. Still gonna end up costing you a pretty penny. The tone rings on the rear are easy with the Artec brackets. Curious about the front though. With your year JK, youíll need to have all 4 wheel speed sensors working. Be curious to see what you end up doing there and what brackets end up going on the front.

    Ballistic fab also makes a good kit. And the shaved gears are readily available from many places and only slightly more costly than original.

    yea, i'm just thinking about it more from the stand point of if you were out in Moab or something. it's a bit harder to get replacement shaved gears quickly.

About us
ďwayoflifeĒ is a moniker that Iíve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
