Reply To: Rear axle spline change

And of course you old timers know how to check if an axle is cracked (at a swap meet or somewhere where you are not close to a magnaflux unit):

Hold the axle up by two fingers under the bearing flange, hit the spline end with a hammer, and see how long the axle rings. If a P-A size axle rings for about 30 seconds (hold your ear close, to note when the ringing completely dies out), it has no cracks. About half that time (depending where the crack is) means it has a crack.

Cheers,
