Purchased the whole set of parts as identified by the videos. (Bottom) dryer duct assembly, (top) dryer drum support assembly, (top) four bearing strips. Installation videos were excellent for both diagnosis and final fix. Note: videos didn't strongly call out the bearing strips as being a separate part to purchase. Buy them (you need 4).
Installation was 10-15 minutes, saving the cost of a repair visit and the COVID exposure risk associated with that.
