Rear Axle Rethreading Help
If you have damaged the threads on the end of the axle removing the hub, they can usually be straightened with the help of a tool.
If your axle looks like the one above, you need a tool like the one pictured below. It is shown in the closed position.
This shows the tool in the open position.
To use the tool, clamp it on the axle threads as far in as possible. Tighten the thumb screw by HAND, and unscrew the tool off of the axle end. You may have to do this four or five times before the threads are corrected enough to put the nut back on by hand.
If you need a tool you can borrow one with a deposit here
