2004 lly 2500 I have experienced a click or pop felt under my left foot when I start my truck and sometimes after shutting it down. In park, and not moving when this pop is heard and felt under my feet. loud enough to be heard easily and felt as well. Feels like pressure is winding up and then there is an audible pop/click one time. Intermittent and wondered if anyone has experienced this..
