The first order of business is to find a donor truck to pull this axle from. Our local junkyard had our axle buried underneath a rusty '80 Wagoneer. We had the wrecking yard pull the axle out on a frosty December day (it was 5 degrees F), and the Jeep was literally frozen to the ground. If the Jeep you pull your axle out of was like ours and had been retired for a while, be prepared to rebuild the hubs, replace ball joints, tie rods, brakes, U-joints, and so on. Basically, any wearable parts will need servicing or replacement.
