Noises on spin:
Drive belt disintegrating will give those symptoms.
Drum bearing failure will cause the pulley to go out of line and the belt run off.
Brushes wearing out would make a crackling, roaring noise, but is unlikely to cause vibration. They are held by two screws on each holder – if they are not shifting, you will have to split the casing and remove the drive motor for better access.
Power off as you investigate,
