Failure is imminent!
 

This is a new, stock spiderbox axle with all of maybe 1 hours of total time on it (test stand and actual on the ground running). Note the twist in the splined portion. This was one part of the axle that I thought might be safe enough to consider using in a new axle design. At this stage i'm mounting the 22s, but i do NOT expect this to last very long at all before shearing.
