Diff and especially the locker are working well to break both axles near the same time. Probably a defective batch if they were bought together. IIRC, diff was high centered when this happened? Still weird, though!
Edit: Was it difficult to get the pieces out of the birfs. Seems like the clips would make it difficult to extract the pieces.

Hard to tell from internet pictures, but it kinda looks like the inner splines of both Birfs are ground down, which might mean replacing those anyway.
I think what you are seeing is once the shaft broke there was only 1/4"-3/8" of spline contact with the birf and shaft and they spun probably during the extraction and it just wore them down. I imagine there is quite a bit of sparkle in the grease....
After reading your post and re-examining the pics, I'm thinking the end pieces are still in the birfs. Wow, it might be tough to disassemble them. I was looking at the pics I took of mine when I rebuilt it to get an idea of what's left in the birf and I don't have a good one to see where the clip is in relationship to the breaks. If splines are still good & the clips are intact in their slots, I don't know how you'd get the pieces out without damaging the birfs.

Wow. Good effort to break both at once!
The long one twisted off clean! Short one not so much.
Both look like they broke 3/16 in the birf?

Probably best to just remove the cage and pound it out either direction.After reading your post and re-examining the pics, I'm thinking the end pieces are still in the birfs.

IIRC, you need to remove the clip to pull the cage out. The clip holds the axle in and also keeps the birf together. Without the axle intact, there is nothing to pull it out of the birf. It's the weight of the axle that busts the clip when you smack it with the pipe method.
Huh. Haven't done my 80s birfs yet, but when I my 40/60 birfs I just rotated cage, knocked it over with brass drift to remove the balls one at a time to get it out. Not seeing anything stopping you from doing the same with 80 birf but I've never touched one.
On the 80 (and also my '81 mini) the axle, birf and outer axle are all one assy. To disassemble the birf, you break the clip by putting the assy in the right sized pipe and smacking it on a hard surface. The weight of the axle breaks (or deforms) the clip and the axle is separated from the birf and outer axle. Then you can pull the cage out of the outer axle and de-grease and maintain the birf. Before doing this, you need to have new clips to re-assemble the birf.
Edit here's a pic of my short side front axle assy before rebuild:

I see, but what is stopping you from rotating the whole cage to remove the balls? Whole thing should come out after they are removed.
I watched the video to about the 5 min mark. The video would be good for a rebuild reference for details. The question is, how far does the axle protrude past the clip. It might stick out far enough to prevent full movement of the cage to extract all the balls. But if not, you'd be right. I'd sure give it a try! But, I've never broke an axle such as this.
30 spline cages will be a nice upgrade. Actually nice that you broke them both at once so you didn't end up with one warrantied 30 spline cage and one old 24 spline.

I have been running these axles since 2016 so I don't think it a defective batch.
I haven't been able to extract the the pieces.
They are ! and they do need replacing
The birfs are not rotating as intended and the splines are definitely ground down.After reading your post and re-examining the pics, I'm thinking the end pieces are still in the birfs.

Not sure why they let go, there was no drama. zero bouncing/shock load both front tires were on lose dirt/gravel
Correct
Correct
We shall see how the warranty goes, looks like they just replace what damaged.
Definitely what to go with 300m 30-30-30 axles Ultimate CV Axle Set for Land Cruiser VDJ ('91-'97) - 300M - https://www.rcvperformance.com/ultimate-cv-axle-set-for-land-cruiser-vdj-91-97-300m.html
I hoping they well give me a credit towards the new set and I can just pay the difference

Small bit of damage to the inside of the ball.
I well probably take the dremel to that and smooth off the high spots.

I'd bet that's the short side. That extra piece dropped into the ball and "massaged" it until you pulled the DS and flange.
I imagine they'd warranty you to the current 30 spline 4340 CrMo axles and maybe give you the opportunity to pay a differential for the 300Ms.I have been running these axles since 2016 so I don't think it a defective batch.

The stub and the cage on the 4340 sets are 300M - only the inner shaft differs. Or so says my Google-fu

I am wondering if that crack will effect how the new seal sits in the axle?
Don't think it is a crack, just grease.
This is how I remember it being when I bought my RCV’s right around the same time as Richard did 2016 maybe early 2017. Stubs are 300m and inners 4340 unless you payed $300 more which I did not. I did get the set with 30 splines at the birf where as the set in question here are 24 spline at the birf which was standard fare from RCV at the time.
