[Vwdiesel] Oil in CV Boot

[Libbybapa at wmconnect.com]

There is a plug that goes in the center of the drive flange.  It looks like a 
little hockey puck, kinda.  That is what is leaking.  The flange seal leaks 
to the ground when it leaks, the plug leaks into the boot.  Try to get 
replacement that don't have a hole in the metal backing as those ones last just about 
forever.  The factory ones have a hole in the metal and the rubber covering 
the hole cranks in time.
