Do-It-Yourself Story

The center shaft of one of the drum roller wheels had disintegrated so the roller wheel was moving all over the drum roller axle. I replaced both drum roller wheels and their shafts and lubricated the idler pulley for good measure as it was not spinning as freely on its axle as it should. I had ordered new tumbler bearing kits too, but on inspection, the originals were just fine and I did not replace them. I cleaned up the considerable lint and dust from the inside of the dryer and reassembled it. It now runs whisper quiet like it should.
