Hey thanks for info. So I'm a pretty good DYI person (engineering background) so I may contemplate replacing the bearings. But before I go the bearing replacement route I have a couple more questions.

Provided I have the right tools, is it faster to replace the bearings or is it faster just to swap out motors? My time is important also so this is why I ask.

Also, I'm sort of leaning toward replacing the motor because I'm thinking a newer motor may be quieter? Do you think this is true?

Are there models of 1HP motors that are known for being exceptionally quiet? Or are all single speed 220V motors about the same when it comes to noise?

Thanks again.
