CHARLY,
I have a similar noise in the same place, but mine seems more pronounced when turning a corner at slower speeds. I had a conversation with Mike Stenhouse about this noise and he said something to the effect that the noise was common and not much to worry about. (I don't remember his exact words and don't want to quote him) Then again, he has SPF 218. I would hope they would have cured the problem by now.
I will be extreemly interested in what you find.
I will take take Mr. Fixit's advice and check CV's and diff' mount next time I have the car up on jacks.
