[Vwdiesel] Re: Oil in CV Boot

[kevin.jack at primus.ca]

Damn....that means I didnt have to change the final drive seal. I hope it 
goes on easily. 

I took it apart on Saturday, so Im having trouble remember that little seal 
in the flange. Ill check it out as soon as I arrive home. 

As for the methods of removing the CV driveshaft, I have been following 
bentley. I find the manual lacking in diagnostics. I didnt know which seal 
to change....so now Ill change both. 

Ill probably have to go to the dealer for parts.
