Fix for Marantz UD7006 Blu Ray player with disc tray noises/ vibrating

I've read about this problem on forums and just a few months ago mine started doing this. When you put in a slightly warped disc the tray would make awful noises caused by the tray being very thin and too close to the high speed disc. Knowing this i figured I could raise it up a bit so disc wouldn't be very close to tray anymore. If you try this use rubber washers mentioned-metal washers may possibly bounce around a bit and cause some vibrations unless they are glued down and I wouldn't risk glue in this situation.
