Check the panhard rod and the drag link. One of them might be bent so bad, it's hitting the axle tube, and keeping you from being able to turn. Remember the pics of how badly I bent mine when I replaced it with the RTE piece? I could only turn in one direction all the way, the other about half the way.
If you broke an axle; they're cheap to replace. You still have the stock 10 spline right? If so; you can get replacement stockers from any of the forums by listing a wanted post; people usually sell the stock ones for 10-20 bucks per side.
Good luck.
