Product review (5 stars): Factory washer belt,  works like new
Washer seems quieter with the new belt. I had the washer apart to fix another problem and noticed the belt "dust"on the motor and some cracking on the belt and it just felt brittle. I went ahead and ordered and replaced because I knew that belt was likely to completely fail any spin now. I think it had been slipping for a little while. I was really surprised how far the old belt had stretched. I would recommend replacing the washer belt every few years, especially if it gets daily use. A dryer belt will go probably an easy 10 to 15 years but it is under a lot less stress.
