Keep in mind that there are three seals beneath the CV joint.  The
disc in the center of the drive flange and the flange seal have
already been mentioned.  I have changed them about a dozen times and
am no longer hesitant to do it in the driveway.

The third seal is an o-ring that fits around the circumference of the
differential adjuster (large aluminum cylinder) beneath the drive
flange.  The black plastic retainer holds it in place.  I have
replaced this seal in my garage with one rear wheel on a stand to
minimize gear oil loss.  Scribing a clear index line and carefully
counting the number of turns to unscrew the adjuster is critical to
success, as this adjusts your ring/pinion engagement inside the
transmission.  With any luck, replacing the two outer seals will fix
the leak.  If not, you will have to go back in and do the third.  I
bought the seal from the VW dealer for about $5, and the proper tool
for unscrewing the adjuster was $90.  In retrospect, I could have made
my own tool from aluminum or even plywood.
