"Another Engineering Opportunity" accepted. Used low tech approach and fixed bent axle tube. No way to put it in a press, at least my press, so I came up with a backyard fix. I measured axle tube and eyeballed it awhile. Once I figured the correct place I cut the axle tube, opposite the bend. I cut it about 2/3 the way thru with a cutoff wheel. I removed axle, supported tube on my big jack stand, took my dead blow hammer and went to work. Approx 6 to 8 blows closed up the gap and checking with a straight edge and square the axle flange now is square with the center housing. Beveled the cut and welded it back up. Good as New! I should have suspected something as there were slight groves where the U bolts held it in. I attributed that to loose bolts and the axle housing rotating back and forth slightly. Now in retrospect it may have been due to a collision. Oh well problem solved...........
