Rear End Failure

I'm wondering if this is some kind of alignment issue (or rather misalignment) of the drive shaft , diff mounts, etc, basically everything connected to the diff. Unless you won the worst lottery and got two terribly defective rear diffs I'm at a loss. Where the bearings screwed at all, which could/would cause such issues.

Misalignment of the driveshaft to the diff would cause vibrations, noise, premature failure, wear, etc
I specifically asked my service department to check my driveshaft after 2 failed PTU's and RDU's. They found nothing with that but said the RDU had the wrong gear ratio. Mine is driving great now after a 4-wheel alignment and proper gear ratio differential.
