4325 is fine, especially in light of the success they have had.

If they can through harden and keep the shaft straight, go for it. The
entire axle shaft will be stronger.In light of previous input, perhaps
we should request magnagloing the keyway area to be assured that quench
cracks do not emanate from the sharp keyway corners.

I don't have a problem with this, either. I have always been puzzled by
the factory design. I'd be amenable to the advice of a modern axle
manufacturer.

No problem with this, either, although I don't see the need for it since
we are unaware of any failures at this point. A new nut and washer
should be supplied so purchasers don't have to track these down on their
own.
