So, the dealer finally got the new driveshaft in and replaced it, and IT FIXED THE VIBRATION!

All is well. It was, as suspected, an issue with the driveshaft that caused it to be out of balance.

Extraj, Could you do me a big favor and take some photos of your new driveshaft U-Joint phasing...

I suspect my dealer may have installed my permanent-fix-recall driveshaft with improper U-joint phasing, and I would like to compare a known-good configuration with mine.

The reason I suspect this might be the cause of my vibration problem, is that from looking at the geometry of the 3-piece drive train angles, I think the U-Joint phasing might be somewhat counter-intuitive, leading to installation mistakes. Perhaps such a mistake was actually the cause of your vibration as well, and replacing it fixed it inadvertantly.

It would be much appreciated. One photo for each U-Joint. I believe there are a total of 4 of them.

Nevermind, After looking at the service manuals, I no longer believe my vehicle's problem is with U-Joint phasing.
