My understanding (through three visits to the dealer) is that some of the lashing compound is remaining in there and causing the noise, By flushing it and refilling 3 times along with some figure 8's etc. removes any remnants of the compound. Maybe someone can find the bulletin and publish it here.

Edit: I am trying to get a copy and will post it here.
