When you try something that hasn't been done before you can run into some issues; as with any project vehicle, our Ultimate Avalanche was swinging from fun to frustrating. When we last checked in, our 2003 Chevy Avalanche was stripped and on the rack at Off Road Unlimited, plus we had just picked up two brand-new axles from Dynatrac. The plan was simple enough: Put the axles under the truck, use suspension components from our friends at Tuff Country, and add an Atlas transfer case for good measure. The problems arose when we wanted to incorporate our special rear axle with rear steer, and make the computer-controlled transmission communicate with the geardriven transfer case.
In the end almost everything worked, and we only had to throw a few things across the shop in frustration. You would think that being big-time magazine guys, we would have all the cool stuff and not have any problem building a rig, but that is only slightly true. We do have all the cool stuff, it's just tricky to put it all together on an unusual platform. Follow along as we get our Ultimate Ulcer--er, Avalanche--closer to being a trail-taming freak machine.
