Littlefeat. You do have us wondering what your problem could be. A broken axle [ but if it has stretched and broken, would not the diameter be reduced ] !!. If it has sheared of, has it splayed the broken end.?
Please get it apart and let us know what has caused the problem.
If you have to use a heavy slide hammer to get this apart, get help. Someone will need to hold a heavy sledge hammer against the swing arm bracket or you will bend the swing arm.
We used a very large broken truck axle with a chain attached, in order to remove hubs from some vehicles. That's brutal, but the only way some times.
Shit. How did I miss those last 2 posts.
You must have had to grind through the axle spacer to cut the axle. That's bloody brutal. With the right thinking and the right tools you can achieve lots.
