A couple years ago, a creative fellow from down under explained how he straightened an early axle using a lathe and torch. He mounted the axle housing in a fixture held by the chuck and slowly fed a large cone center into the outer end while heating a section of the housing with a rose bud slowly turning the axle. The combination of heating the axle where he wanted the bend and slowly feeding the cone got both bearing holes in alignment. I tried it and it worked like a charm. The fixture in the photo has a plug that enters the bearing hole to fix the position of the large end. When I started, the outer end had .350 inch run out. As you can see, it is now in alignment. Many thanks.
Richard ; Nice that you had good success with straightening the rear axle.I have it done several times with great success .
