Damper springs. Maybe? Lub in the spring slots.

  Hi all.  Customer has a Young Chang grand aprox. 10 years old.  When the damper pedal is pushed, a "crunchy" sound can be heard in the back action.  The damper levers sit on a rail that is covered with felt.  If I lift the damper levers with my hands and then push the pedal up and down, the sound goes away in that section.  

   

  Is the rail/tray felt making noise as it rubs on the bottom of the wooden damper levers or is the sound travelling from somewhere else?  I'm going back tomorrow and may try to rough up the felt but I wanted to ask y'all first.  

   

  Thanks in advance.
