Turns out it was a zipper caught between felt and drum. That began to rough up the glides, which started tearing up the felt.
Opened it up that is to repair videos here. Saw the problem and was able to order the appropriate parts. And since I had it open, I decided to change the belt and idler arm. Got the parts in a day. Fixed by the evening. Repair videos really walk you through step by step. 46yr old single mom. Saved me from buying a new one or paying a service to fix it.
