The noise was quite annoying so after reviewing comments on this site I realized the noise was most likely from the idler pulley. So ordered that plus a couple of drum rollers just in case. Found a YouTube video showing how to disassemble the dryer. Took about an hour but wasn't too difficult. Promptly replaced parts in a few minutes. Had to fix the dryer vent hose since I was already back there. Put it all back together and now noise free. This site is awesome and has aided my repairs 4 or 5 times now. Thank you again!
