Ray & drolston .....Guys- This is "THE" classic symptom, and eventually the end result of NOT TIGHTENING that BIG AXLE NUT to the proper ~205+ foot pounds of torque, or at least something very near to that figure. That kind of torque is needed to 'fix', or 'set' that hub taper & axle taper in such a fit that the hub and axle essentially become ONE....NO movement between the hub and axle can take place, to continually work the hub, key and axle all against one another, to the point of causing a crack to form. That is right where they always crack .....from running the big nut
TOO loose at some time in the history of the axle.
In the first picture of
drolston's broken axle STUB, you can see the end of the axle key (at 6:00 o'clock) at the break. Second picture shows a lucky-owner's axle, caught before the crack could fatigue to the point of failure. TIGHTEN those nuts, guys! DD
