The new roller support wheels helped quite the dryer. The other contributing factor was the outer door frame 'felt bearing' and the rear drum ‘felt-seal’ had a lot of dust, dirt. lint and other contaminants in the fibers. It was vacuumed clean and now the drum turns much easier.
In addition, I cleaned the belt and belt-pathway and lubricated the Rollers. Some say not to lube the wheels, but it helped a lot. It doesn't squeal any more.
Thank you for the parts!
Brian.
