I have brought this up before, if you weld (or just tack) on hardened steel it will more than likely break, in 6 months or so. Depending on the amount of heat, and time, it brittles, and failure is on its way.
That's pretty much true. Looking back , I bought these Strange axles back in 1975, No Twisting of the splines, never had to change the bearings . Thousands of wheels up 1/4 mile runs. I doubt if there going to snap off anytime soon.
it's ok to butt heads, just don't do it with a butthead
