Vertical backcheck noise?

Friends,

I came across a new one today, I think.  1983 Everett school model
studio piano.  While tuning I would hear a woody-sounding click on
nearly every note, very consistent, similar to the sound you get if a
jack tip lost its felt.  Nothing I checked seemed to diminish the sound
until I took a length of 1.0mm center pin bushing cloth and held it
where it would get sandwiched between the backcheck and the catcher when
the key was depressed.  That squelched the noise markedly.  The
backchecks have only 1/8" or 5/32" of felt, which is not all that
unusual, I guess, but it seemed pretty hard to me.

So I think what I need to do is replace all the backchecks, but because
I've never run into this before, I'm asking if anyone has ever had to do
this on a piano only twenty years old.  Is this indeed the problem, or
does it just *appear* to be when it's actually something else?  Thanks!

Regards,
Clyde
