DA* 60-250mm light grinding noise?

When I point my DA* 60-250 down with the lens cap on and let it hunt back and forth on AF it has the same uniform sound, but when I point it upwards, when going towards infinity it makes a funny sound while hunting, almost like the slightest grinding sound. Grinding might be a bit of a strong word, maybe it is something making small vibrations, but it is a clear sound not present when the lens is pointed down instead of up. It focuses fine by the way as far as I can tell in normal situations, but the sound has me concerned.

Has anyone else experienced this? Should I be worried/post a video of the sound?

Thanks! -LE

Loren,
I checked out my 60-250 for you. It makes pretty much the same noise when pointed either up or down.
My DA*300 made a squeaky sound when I first got it but it is quiet now. I guess there is a little break in period.

regards

Much appreciated Gary, I checked my 16-50 and it does the same though not nearly as loud as the 60-250
