[s-cars] Driveshaft alignment

[JR]

OK so I replaced the center support bearing (bought one from 034 
Motorsport)and repacked the dried out grease in the front CV joint on 
the drive shaft.  I put everything back together the was and test 
drive.  I get an awful vibration at about 20 MPH.  I understand this is 
a symptom of the shaft not being exactly aligned.  The part is 
new/different and who knows what else isn't exactly the same as it was 
what with everything settled the way it was and layers of rust coming 
off with each part.  I suppose I'll have to go buy an assortment of 
washers and see if I can dial it in.  Anyone know what the best way of 
aligning the shaft is without a specialized tool from Audi?

Thanks,

JR
