[pianotech] Noisy Yamaha damper tray hangers

[Bob]

Everything looks metal. The hangers are just like upright hammer rail 
hangers - three L-shaped hooks in bushed thingies. It sounds like the 
noise is from there, and if I either lift the tray by hand, or grab the 
tray and move it a couple of mm side-to-side, it honks. It feels like 
those bushings are contaminated. Is this something others have 
encountered in Yamahas? Is there a quick fix?

Thanks,
Bob Davis
