Changed drum belt, drum support rollers, dryer drum guides, drum guide felt pads, belt tension pulley and motor. I had to change the motor because the damaged drum belt pulley is not replaceable by itself. Changing the drum support rollers, dryer drum guides and drum guide felt pads was only a precaution since I already had the dryer drum out.
Watched the videos on AppliancePartsPros.com. All parts arrived super fast and very easy to do it yourself.
