Product review (5 stars): Made my noisy dryer quiet!
I ordered this replacement pulley because my dryer was making just awful sounding noises. I took eerything apart and could see that the wheel on the pulley arm was very loose and wobbly.  Grease didn't help quiet the noise, and there was no way I could stabilize the wobble wheel.  Ordering this part though was the perfect fix. My dryer is super quiet and I'm sure it will run now for another ten years.
