It sounds to me like it's the damper lever felt/lift rod interface. It doesn't happen when the pedal is first being used, say for 20-30 presses of the pedal. Then gradually, the creak comes back.</DIV> <DIV> </DIV> <DIV>I don't know what else to do. Did I miss anything?  Any ideas?</DIV></B></FONT></DIV> <DIV> </DIV> <DIV style="CLEAR: both">Dave Stahl<BR><BR>Dave Stahl Piano Service<BR>650-224-3560<BR>dstahlpiano@sbcglobal.net<BR>http://dstahlpiano.net/<BR><BR><BR><BR></DIV> <DIV class=AOLPromoFooter> <HR style="MARGIN-TOP: 10px"> <A href="http://pr.atwola.com/promoclk/1615326657x4311227241x4298082137/aol?redir=http%3A%2F%2Fwww%2Eaol%2Ecom%2Fnewaol" target=_blank><B>Check out the new AOL</B></A>.
