Did you look inside to see if the GG is in fact rubbing something in there. I have the m2 encore, and it's colliminated from the front exterior of the adapter. It has nothing to due with noise though. it only sets the focal range.
It could be the actual motor going bad and causing a noise due to the tiny internal parts wearing out.
I would open it up and manually spin the GG To see if the motor is causing the noise.

I assume your talking about the original M2 right. I had the same issue. Its not hitting anything, its the motor going bad, or just funny. When I took out my motor I noticed it only made the noise when it was tilted at certain angles. Replacing the motor helped a bit, you have to get the ground glass tight on it and totally flat (perpendicular) to the motor or it will make noise. Its hard to do, and one of the reasons they upgraded the technology.
There is a link somewhere on the redrock forums on where to by them. There like 50 cents each, with a minimum 10$ order. If you can't find it I have 9 left I ship you one for 5 bucks or whatever.

I had the same "issue". It can be two things: The small bearings in the motor are worn down, and that's when the sounds starts. You need a motor replacement. If you are a bit handy, you can just order a new motor and change it yourself, it shouldnt be too hard as you can loose the glass with the holder. So just find a new motor that has approx. the same size.
The other thing it can be, is pure physics.... Please bare in mind that I'm from Sweden and that my english isn't always the best... When a flat circular object is spinning in high speed, and you try to tilt it, a physical force will be created that will try to stop the tilt from happening. As you know, this little glass won't stop you from moving you camera left and right up/down, BUT it will react on it and it will try to keep itself straight, that's when the physical law collides with your intention of moving the rig.. This is actually the only thing that adapters with vibrating glass has as a plus over DOF adapter with spinning glass... So there is actually no solution for this, some adapters suffer more from it than others, all spinning adapters that I've tried definitly sounds more as the motor has to take all the torque energy when moving around a bit faster.
It's being explained here a bit, start looking at 23 minutes in to the video, think that wheel being your groundglass: http://www.youtube.com/watch?v=zLy0IQT8ssk
