Note the wide flat between splines that shows shallow spline axle.

I don't know if one could be cut that straight, straightest break I've seen.

That's the cleanest break of one of those axles I have ever seen. I pictured a diagonal twisted fracture with all kinds of roughness and lots of metal chunks missing.

That's why I was questioning chances of just slipping a new axle shaft in and putting back to work.

I still might want to change the oil and check and clean magnetic plug(s) then after it has a few miles on it pull the magnetic plugs back out and see what there might be on them.

Would be worth it and make a video to post on line just to see how many "Likes" you get!

Yet those are the same people disassembling and ‘Polishing’ old taper roller bearing assemblies and welding broken crankshafts cams and blocks. Just saying a Little dubious of any life expectancy on any of those hours and hours of Fixes.

Looks like a break on a Weyerhaeuser truck with the scored axles. It obviously isn't because you cannot see the indent of the scoring. They used to score them about a 1/32ed deep and about 2" in from the spline. Scoring them and putting the scored end at the hub reduces searching for parts in the rearend. It also speeds up removal and replacement.
