Determined it was probably the main bearing that was making the noise so ordered a rear drum bearing kit. My son-in-law and I took on the task after watching your how to video. He did most of work, I was just the holder of a flashlight or a screw when needed. Following your video instructions it was an absolute piece of cake to replace the bearing. Took a maximum of an hour and the dryer sounds like it did when new. Fantastic service as parts arrived within 5 days and your instructions are fantastic. Anyone who can use a screwdriver should be able to make this repair.
