It started squealing a few months ago during the very first part of the wash cycle and near the end. Over time its gotten louder. I figure it will fail eventually. I want to determine where the sound is coming from. I haven't pulled the washer out yet but if I do that I won't be able to run it anyway. My guess is its pump related. Years ago having worked with pumps usually the pump impeller shaft or bearings go out first before the motor. I'm hoping its not the motor because its the more expensive part.

Thanks for any insight on this.
