You can sometimes repair a SLIGHTLY bent axle by clamping its unthreaded center section in a vise, placing a sleeve over the threaded end, and applying a bit of leveraged torque to it. However, many steel axles will break if cold-worked twice (bent, then straightened).

Rear wheels with 6- or 7-speed freewheels (as opposed to modern freehubs) are somewhat prone to axle breakage or bending at the right side bearing cone.
