I believe this just bad engineering.  I've looked extensively at many different Tuff Torq transmission diagrams at TuffTorqServices.com.  Husqvarna seems to be the only ones using this type of axle and hub key system.  I just had the axle snap inside the hub right where the keyway  starts.  My tractor is a YTH2454 and yes I was mowing on flat ground.  I don't use any ground engaging attatchments.  I checked both my hubs and they do have quite a bit of play with both old and brand new axles.  I'm thinking about throwing away the new axle I just bought, ordering new K46 axles made for a different manufacturer, and then buying that manufacturers hubs to go with them.  I think it with be cheaper and less repair work in the long run.  Again I thinks it's just a bad hub/axle design all together.
