Before we started on the front suspension we assembled the axles. Dynatrac built the Dana 44 axle to fit the truck, but also so that off-the-shelf axles would fit in a pinch. Our long-side axle is from a '74-'79 Jeep Wagoneer and the short-side is a '73-'78 GM 1/2-ton truck, both with 30-spline ends. The stub shafts are 19-spline deals like GM used in '77-'87 1/2-tons for strength purposes. We are running chromoly shafts from Superior Axle and Gear, 300M U-joints from CTM Racing, and some Warn premium hubs. This should hold up to our abuse with a lightweight vehicle.
