Makes me wonder if under the lip of the eyelet - a crack in the rim hole has developed. That would result in the eyelet shifting with each stroke of the wheel causing a click. Have had several customers in the past who reported clicking sounds before the eventual - the eyelet ripping out of the rim.

If the eyelet rips out later...then it'll be a DOH! moment.
