Product review (5 stars): Roller/pulley for clothes dryer
My Maytag dryer worked quite well for about twenty five years.  I bought it for $100 at Salvation Army.

Then it started squeeling whenever I started it.

The Roller/pulley mechanism, and all the little parts that came with it,
fit right into the mounts on the dryer.  We didn't have directions, so it
took an hour or two to get it right.  Since then (about a month ago), it has
worked perfectly.
