Pump making whining noise

[monkeyratman]

I have a 2hP Century Centurian switchless pump. Yesterday I noticed it was making a high pitched noise I had not heard before. Plenty of water in the pool. Filter presure normal. No debris in any of the primary filters. Has anyone had a similar experience. I am hoping it is not a bearing going bad. Thanks.

It has to be either a bearing or the seal. Most likely a bearing.
