Thanks for the replies.

Right about the rotor and the hug being one unit at this point, since we are re-installing the disk assembly.

I measured using the magnetic base on the hub (so I'm ok on that), and yes, what I was looking for was play when PUSHING and PULLING the disk towards and away from me, i.e. direction of the spindle.

I just found it hard to NOT to slightly rotate the disk at the same time. If I had gotten ahold of the approx. $300 Mercedes Benz holder for the gauge as photographed in the manual (and I don't think any one of us amateurs has one of those), I am sure it would have taken care of the problem.

donbryce - I will look at your setup more carefully and see how you did it. Seems you may have addressed the problem well.

What really gets me is how sensitive that adjustment nut is in terms of creating the right tension on the bearing. I mean we are talking very fine turnign movements, and even tightening down the hex lock screw can alter the reading!
