Product review (5 stars): Machine is quiet once more...
We had a loud squeal coming from the dryer and ran the motor without the belt to test whether the motor was the source. When it proved to be the case we ordered this part with the cheapest shipping method. Not being a prime client I had to wait five days before they shipped, but that was my choice (we have two dryers so wait is not an issue). Part came within two days of shipping and installed easily (after viewing a dryer replacement youtube).

Machine is back to a quiet hum.
