I Broke Another... racing story

[rocco16 at sbcglobal.net (LEF)]

Have you heard about this "fix"?  Tightening the axle nuts to over 300ft-lbs supposedly helps
reduce the chance of failure.  I read this from a few racers...

All the axle nuts do is force the two wheel bearing inner races together.  The hubs themselves are not affected in any way...unless, of course, the bearings fail.  :)

 so you're right, either replace every
year or so or possibly heat treat.

Metals have to be of a suitable alloy to benefit from any kind of heat-treating that would help us here. You are talking about hardening and/or tempering which require steel alloys that are "heat-treatable".  If the items in question are made of a non-heat-treatable alloy, then running them through a heat treatment would be a waste of time and money because the metal would not respond.
