C-Clips (c-washers really) in the rear diff on semi-float? I don't see a true BFH on the ground either.

No c-clips in semi-floats. Just unbolt the hub/shaft assy and it should pull out (done it before).
Not sure how anyone expects me to add heat to the internals of the axle housing. I guess i could light a fire inside it
I actually don’t own a BFH any bigger than the one pictured. Never needed it until now i suppose
bigger chain....

Got it. Now the issue is that I can't get it back in...the bearing is slightly dislodged. I'll try to press the bearing on and see if that gets the shaft in further
Might be time to throw in the towel and buy another shaft altogether...
Semi-float is some bullish*t. So are OEM rear lockers when you're really using them
The shaft I broke back in November broke at the same place. Seems to be the weak spot on the 100 semi floaters (at least the locked versions)

What finally got the shaft to dislodge at the hub?

Yesterday I was attempting to pull the shaft out of the hub assembly. Today I pulled the entire assembly with relative ease
Now I can’t get it all back in because I managed to pull the shaft off the hub slightly yesterday…gotta press it back on then i can re-assemble
Here's the old 80 thread on the subject of OE rear lockers being less than ideal- Twisted rear axle shaft - https://forum.ih8mud.com/threads/twisted-rear-axle-shaft.239583/post-4572152

Here are some relevant threads I've stumbled across in regards to this.
I'll be attempting to "machine down" my splines on this shaft with a grinder/flap disk next week. I plan to replace the shaft eventually and will have that one milled on a lathe.
here is a pick of a production shaft after turning.
You'll see that the roots of the splines are still visible. The shaft has been turned enough to allow the collar to rotate on the shaft in that section but now the collar will be held in place better to aid in installing.

no problems with anyone... at the moment 
here is the drawing that I've come up with. If you want to use it it's all on you.
Right now I wish I had more data that just two twisted shafts but it is what it is.
My bad shaft gets to poly performance tomorrow so I'll call and talk with them on Monday.
My first inclination is to only remove the splines outside of the collar in hopes that the twisting stays localized there and eventually breaks there as well.
I don't know right now and need to chew on this a little more in hoping that I make the right call.
I included a PDF...

I doubt many 100 owners have had this issue yet and if they have I need to meet them.
Is it possible to run standard LX shafts without the longer splines with something like an airlocker?

Yes lots of 80 guys have had this discussion. Christo chimed in a fair amount back in the 2010s recommending something like an ARB to prevent this issue

I’ll be buying a spare shaft soon. Not sure what I’ll do long-term. It will honestly depend on future problems which will hopefully be minimal now that I’m more cognizant of this “feature”
