Young Chang crunchy damper sounds

[Michelle Smith]

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.
