A drive shaft is likely mild steel tube.
The tube portion can be cut/welded easily.
Axle shaft is a solid bar of heat-treated spring-steel.
Not weldable and barely machinable.
I think it can be shortened a little as long as there is enough splines remaining.
Perhaps a snap ring groove can be cut with a grinder. |

I think Jeff is going to shorten and cut splines in a subaru axle shaft to fit a vanagon CV. Looking on YouTube, It looks to be quite simple as long as you have an indexing head and the spline cutting tool for your mill. Nor does it appear that an axle is difficult to machine - but that depends on how hard the material is on a subie axle as you mentioned.
For a reversed subaru trans, I think the idea of using the Subaru axle shaft makes way more sense. |

So back to the ware pattern:
I’m putting together a cable shift 6 speed. I put the subi gear shaft together and got the pinion depth set at .05 using the subarugear depth gage. Sweet, kinda.
Mounted in the case with the front bearing in the pin, I lightly tapped the gear side towards the back of the case, and the inner shaft move back about .109 inches. The provided spacer/washer is water jetted out of stock steel plate. SO if I started to set the ware I would have been chasing it around and probably blown up the trans the first time I jumped on the freeway!
Maybe that’s what you are fighting??
I did have to turn the SG shaft down .01 as it was .008 to big in one spot. I did notice the heat treat has some funky spots. I’ve never seen bar material like that. Makes me wonder??
And yes axles are no problem to cut. It’s all about the carbide grade and speeds and feeds. ( that’s what I do for a living)
