Hey if you need any more ideas, how about taking a cheap dana 44 front or the like, cut the tube off on one side, on the other remove the axle tube from the "C" via the spot or ring of weld in the lathe. THEN just stick the pipe in the next. Just remove the center section more or less and rotate to look like a u joint in your tool box. . Remove one of the spindles and bolt it right on one the trailer. THEN keep the hub/spindle/wheel bearing on the other end. Use the lug nuts to bolt it to a plate with the 8 on 6 1/2 pattern. NOW you have one that will pivot left,right,up,down AND spin. Just like the unimog one but better.
hmm could we incorparate the Diff and then replace it with an ARB so it could be like a power divider on a semi???
MUUHAHAHA
