After noticing the brown marks on the clothing I proceeded to inspect the dryer. It was easy to see that the felt ring at the back of the drum had deteriorated completely and was letting the drum rub on back of dryer removing the paint. It was also collecting dirt around the same ring. Upon taking apart the dryer, I decided to replace the front plastic bearing rings, the drums felt ring on back, a new belt, rollers, lint chute gasket, blower housing gasket, and also repaint the back of the dryer and the inside of the drum. I easily found and purchased all parts including paint on this site. After sanding, complete dryer cleaning, repainting, and installing all new parts the dryer works good as new with no more marks! Great videos on the site also! Thanks
