I had already disassembled the dryer but used the repair tutorial on AppliancePartsPro to identify the parts I needed and how to reassemble. The parts were ordered on line and delivered in a few days. It only took 45 minutes to put it all back together and now is very quiet again. I also replaced the belt, tensioning wheel and a couple of the clips to hold the lid down while I was at it. It was all pretty easy.
