Guys... Need logic explained here over broken rear diff

I'm following this on Facebook. Chick I know took her 2012 Sahara wheeling in Disney, Ok

4" Rancho LA lift, 35s, 4.88 w front locker.
Had a Tom Woods front driveshaft and new yoke installed 2 days before leaving.

Here's what happened....

Was climbing a small rock face, didnt know that it was in 2wd, rear carrier broke in 4 pieces.

Reason it was in 2wd..... CLAIMS THE FRONT PINION NUT CAME OFF, separating front driveshaft and yoke.

So I wanna know ... Does this make sense?
If the nut came off the pinion, could the front DS really separate. I looked at my set (factory) and can't put this together how it's possible.

And Yes, she is heavy on the throttle when wheeling

I can't help you, but all I know is heavy on the throttle = breaking parts.

Sorry to hear about her bad luck. Hope she got it fixed soon.

Heavy is a underestimate

She is trying to blame a friend that installed her DS (for free) that the nut came loose.

I still dont get how the front DS can come completely separated.

And if it did... would it kick off the 4wd light? seems to me the front driveshaft would be slapping around

Sounds fishy to me. Did she really say pinion nut? Or the 4 bolts that strap the u joint into the yoke. Yes the driveshaft would still spin the same speed as the rear. But first she should have known it came lose or someone should have noticed visually and from the poor performance. Second if she knew she needed to fix it.

It's posted as "pinion nut came completely off and was sitting in the universal housing, and couldn't see it because of the skid plate"

Yeah she's full of it. For a driveshaft install he wouldn't have to touch the pinion nut. I don't know how it would get inside the diff. And anyone with a jeep can tell if there front tires are spinning or not offroad.
