+1. Thanks for chiming in though, Mkoesel. I'm glad you got your issue sorted out. It appears that pebbles are primarily involved in the cause of the cowbell sound. I was able to "drive mine off" yesterday, and it's now back to normal. I just wish it didn't happen so often! SO EMBARRASSING for a car of this stature.
