So I see an intact cage in the background. Is that from another joint that didn't explode??
It looks like the shaft may have moved inward and caused the bearings to explode out of the cage. If that is the case, then they may have been well worn and if the trans did move too far laterally may have allowed the extra room for this.
Maybe you can be more clear about what we're seeing in the pics.
Usually when I pull them apart the cage is in about 5 pieces.

The wear has been happening for some time, and finally broke. The wear on the rotating parts within the CV was severe as shown in the photo's. LR does not have these in stock, and I don't know how long the manufacturer will take to ship new ones

No. It's the cage that was messed up. All photo's of the cage is from the broken CV.

They're from the Driveshaft shop. Shouldn't be too much of a wait George.

Did you have locking fasteners on it, or stock bolts? In the assembled picture where the bolts are missing, did the heads shear off leaving the threads broken off inside, or is the entire bolt gone?

Tom,
Just the one bolt was missing. All the others were tight. The bearing must have stopped rotating there, and blew out the bolt. Once the bearing stopped rotating, I'm theorizing this pushed the axle out of the CV grooves. You can see the indentation in the cage.
Porsche axles on the factory cars last a very long time. Tripling the factory tq is asking for failure. The newer versions are tested to 1000 ft lbs. Once I get the new version of these axles, we should be good for a while.

These are the bolts that came with these axles from LR. The locking bolts are on the trans side.

Was the head sheared off? If not, hard to see how a bad bearing could spin the bolt out of the threads?

Tom, I get it. These were the first units from LR. They were updated and are under warranty. If I had a factory 968 passenger side (shorter) axle, it would be in the car. I was planning on going to the test/tune tonight for a few 1/4 slips to share with Sid. Sucks that won't happen.

Personally, I would just get a vanagon axle and use the joints on the shorter axle to have a spare on hand.
I take two spares to the track with me as a minimum.
