Hey Gary,

I tried to clean this thing up- and I'm using a jeweler's loupe (don't ask) to try and figure out the part number....

It Looks like:
201 411 05 47 w 286

It's a heavy steel disc, about 5.25" in diameter, and 2" in width with deteriorated rubber still adhered to the inside of the disc. My mechanic found a picture of it in his computer and it just says "vibration dampener." I've driven it since they cut the offending thing off- and it's actually smoother now than it has been since we bought the car in february.

I went thru my usual online catalogs and can't find anything on it though. If you happen to find out what else this thing could be called could you email me? I probably should replace it... J
