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?<br>

honking damper tray hangers. Is there a fast way to
service these? Hose 'em down with Protek? Or are they
contaminated with something? Is there an easy way to get
the hanger bushings out for inspection/replacement?<br>
