Over time our dryer was getting progressively louder, clicking, clacking, etc. We had a tough load of pillows and it had to run on high for a very long time and afterwards it sounded like some kind of bearing had gone out. When i pulled it apart, the belt was hanging on by a thread, the idler pulley was seized and at least one of the rollers was rough so i figured that I would order all the parts to basically replace anything that moved (other than the motor). Everything went in fine, didn't need to remove the rear bulkhead to get the back rollers (dv209agw/xaa). Dryer is very quite and works like its supposed to now.
