<WBR>Check to make sure all the bolts for the caster are tight. Also check the brace bolts. Perhaps for some strange reason, (humidity change, maybe??)<br>
they loosed up. <br>

<div class=MsoNormal><FONT face=Arial size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">The rear concert caster on one of our Ds “knocks” and I can’t seem to find the “fix”. If we orient it 90 degrees to the player it doesn’t knock, but if the stage crew forgets and it is in line with the player it will knock with vigorous playing. (Fairly loudly, like someone tapping their foot.) The leg seems to be tight. It is the actual wheel. It is the big expensive brass kind, but unfortunately not Jurgen’s. Any simple fix?</SPAN></FONT></div>
