I am not sure what I did to the knuckles when I filed them. But when I did, 
it stopped the noise all together. I guess it took enough roughness, and 
maybe a little corrosion, off the leather, to stop the squeak. 

Now you ask about wippen knuckles. I have never heard of wippen knuckles, so 
I guess you mean shank knuckles. If I tell you what I use, I will get in 
trouble with the PTG police. So I'll whisper it to you, if you promise not to 
tell any one. 

I lift all the shanks up, exposing the knuckles. I then run two strips of 
masking tape from one end of the action to the other, on the knuckles, 
leaving about 1/4" inch of leather exposed, right where it touches the jacks. 
I then use spray graphite, and give it a light coating. That has always 
worked for me. The liquid graphite soaks into the leather, and doesn't seem 
to gum up like powdered graphite does.
