Product review (5 stars): exactly what I needed
This motor was surprisingly easy to install. Google for youtube videos and they walk you right through it.  Literally pull it out,  lay it on its back,  plug and play.  I didn't even need to cut the old electrical connection off,  it fit into to motor.

It didn't make the dishwasher any quieter than when it was new,  but it did stop the awful squeeling.
