whats wrong with the axle tube , is the tube broke off or bent then that is rough but do-able ---------------- or is the tube wollowed out at the end so as the bearing race and seal has nothing to hold on to , if so it is easily repairable , what you need is an outside machinist that welds and has a line boring machine , there is a guy that has done a few for me in the New Orelans area , what he does is to weld up the end of the tube , then he sets up his machine and cuts the tube back to original specs , he use to charge $250 up per tube depending on how much welding he had to do and everything had to be taken apart ready for him to roll , but that was a few years back and I would bet it is more than that now , seems I remember having to disassemble the other side for him even though nothing was wrong over there so he could run his shaft thru the other side axle tube and he tack welded brackets to the tubes on both sides to hold everything in place while he cut with the machine and he would use the tube on the other side if good as a guide to get measurements from .......... does that make any sense to you
