Mike,

Immediately after I sent the post, I did not feel comfortable with it, so I
went to check my pulley.  I was wrong in assuming that the pulley could
loose its form, for it appears to be a solid piece of steel.  Therefore if
there is any warpage in yours its not from the vibration damper as I
alluded to before.  The damper seems to be made up simply of additional
weight.  I am sure the list experts will correct me if I'm wrong.

I apologize if I led you astray, but I was led to believe by my Audi
service advisor that the said vibration damper was a layer of galvanized
rubber within the pulley.

I have the same situation with mine, that it appears to wobble
occasionally.  I have had it for years.  The pulley is solid on, and I have
never had accident, that could have bent it.  What I haven't figured out,
is why sometimes it looks perfectly aligned but others if wobbles, now that
my theory is out the window.  Perhaps just an optical illusion.
