A6 CV joint

[john at westcoastgarage.net]

Hmmmmm.  Well, you'd need a puller with a 12mm shaft about 8-10" long, with 
a tip that would go through a 13.5 mm hole, and a span that would you to 
clear the bulk of the joint and still grip the joint securely without 
damaging the tone wheel.  Doable, for sure, but possibly hard to find the 
tool.  The bolt is simple, fits in your toolbox in the shallowest of 
drawers, and is readily available, as a new one comes in every boot kit.  If 
the brand you buy doesn't have the bolt, you didn't want that brand anyway.
