Busted driveshaft and possibly differential?

So i knew my pinion angle was really bad and im an idiot for driving it but now I'm stuck on the side of the freeway because my car started shaking really bad. It had started to make a lot of noise too but i thought i could at least make it home. When i pulled over i saw lots of smoke and it was red hot where the rear driveshaft connects to the diff. How much damage am i looking at here? Any advice would be appreciated. If its as simple as swapping out a driveshaft, then i would probbaly do myself and then get the pinion angle corrected

Wow that Rzeppa is WELL DONE. Never seen one like that. You might have cooked your pinion seal too. Definitely change your diff fluid and if you see any metal bits, well, you know...

Keep an 8mm wrench in the jeep and take the shaft off, run in 4hi / front wheel drive.

Good news is used ,OEM driveshaft are ez to find & cheap. However, it looks like you could maybe benefit from calling Tom Wood's ...
I agree on pinion seal check and xfer case seal check. Looks like u get trophy for the hottest Rzeppa joint ever.

You probably killed the pinion bearings too.

Yeah, you're going to have to remove your carrier and pinion to inspect for damage to the bearing/seal.

You're also going to need a proper double cardan driveshaft to avoid this in the future.

The good news is that it's an easy job and relatively inexpensive, unless you also need adjustable control arms to dial pinion angle.

DC shafts still require aligning the pinion with the shaft at neutral ride height. Time for adjustable CAs.
