I knew it was the blower wheel that was worn out, inner shaft space rounded and enlarged from years of wear. I ordered a new blower wheel which was a cinch to install. The front of the dryer is easily taken off by removing two screws on the lower front of the dryer. the top is held in place with two spring clips. The blower is located inside the left front blower housing. this is opened up by removing about six or eight sheet metal type screws and then taking off the retaining clip. It is also a good idea to wipe and vacuum the inside of the bottom of the dryer to remove the accumulated lint, toothpicks and dirt to ensure smooth operation. Note that when I ordered the wheel I also ordered a clamp and a retaining clip as recommended by the website. The clamp was not necessary as the wheel comes with a clamp but does not come with a retaining clip. The dryer sounds and works like a brand new machine.
