Dryer tumbler was rubbing on metal

As it turned out, the felt was only part of the problem. The guide bracket had been cut thru by the drum. This all started when a golf tee got stuck in the drum area. It took very little time to destroy the guide bracket. Dryer was built by Whirlpool. Parts are built to the bare minimum. These appliances are designed to break in a couple of years. There is no doubt about it. I installed the new guide brkt, glued the new felt on and put it all back together. The job is pretty straight forward but you need to be mechanically inclined.
