Every shop I found/called in CO would not touch an Audi driveshaft.
Two places told me that my driveshaft "would never balance" after
I had pulled it apart, naturally they were wrong.... :-)

Are you sure that your driveshaft really needs to be balanced?  A bad
center bear or u-joint can really put out some vibration.  I rebuilt
my driveshaft (replaced u-joint, one CV and center support bearing)
without
a great deal of trouble.  The biggest PITA was getting the yolk of the
driveshaft.  Use a punch to mark the orientation of the yolk on the
shaft
and the orientation of the yolks on each half of the driveshaft.  Shop
around for the CV joints, my local Audi dealer had them for a good
price!

No need, good idea to mark the original location though to ensure that
the center support goes back where it was though.
