Shot peening is the process that will improve the performance of the axles
from a crack perspective. If you were making a new slot, then you might be
able to have it milled or ground with a radius, but the existing slot would
be hard to modify without making it oversize. Good news is shot peening is
cheap, and can also help the splines, and the rest of the axle too.
One thing that I always say about crack checking - it only tells you that
there are no cracks now - you could get a crack five minutes after you put
the thing in a car! Also, you don't see cracks that are under the surface
unless you xray. I prefer the idea of getting full floating ends grafted
onto the axle housing - hot rod and circle track shops do this all the time.
