Anthony,
First, it does not hurt a thing to run the van without the drive shaft
installed. It just doesn't allow your AWD to work, but you can run
forever on rear wheel and the front stuff is fine without the drive
shaft installed.
I started out trying to rebuild old syncro driveshafts. However the
problem is that not only do the U-joints go bad and cause vibration
problems but there is also a bronze bushing in the center of the drive
shaft that is under where the rubber flex disc is. If this bushing is
worn at all it will still allow the drive shaft to vibrate and not be
able to be balanced properly. That is why we have been installing and
selling the updated drive shaft for the syncro for about eight years
now. I have shipped these to Japan, Australia, etc. They make the bad
vibrations go away, and they don't have the bronze bushing problem
because the design is different than the old ones. If you ever have to
rebuild it in the future, the u-joints are much cheaper and more readily
available than the stock VW ones.
This is in our webstore under the part number syncrods1
Just let us know.

I thought wheel bearings, but all four are rock solid when shaken. None of the CV boots look bad or have too much movement either, but I wouldn't rule out rear CVs since they haven't been replaced since I've owned it (about 100K miles). Less than 10K on front CVs.
