Looking to find out what the average wall thickness of average axles are. Namely, 14 bolt, dana 60, dana 44, whatever else you know. Reason I ask is next time I do a project I'd like to remove the tubes and start fresh. Why? strength. I would truss and retube with thicker tubing. Next thing I build I want to be light and I plan to catch air. Maybe not 20 foot dune jumps but air for sure, and I don't want to worry about it everytime a tire leaves the ground.
