Product review (4 stars): Did what it was supposed to do
Of course, the installation of the belt was not without its difficulty, but I managed to tear down my dryer, remove the old belt, and install the new one ... only to find out the horrendous squealing noise was coming from the bearing on the tension arm, not the belt.  Oh well.  I ordered that part too and replaced it as well.  Now dryer doesn't make noise anymore (other than the noises it's supposed to make).
