Loud Motor Bearings

Anybody ever replaced the bearings in thier pump motor? My motor is just over a year old and it's already growling / squealing at me. I would like to know the bearing size before I tear into it so I can have the bearings with me already. Do any of you know of a website or something to tell me the size bearings that my motor has in it?

Emerson Motor
Cat. No. ESQ1152
Model T55CXCJH-1343
HP 1.5 SF 1.5 RPM 3450

I know this motor is fairly cheap at around $225 and is probably considered a "throw-away"... But I'm trying to save all I can. Any help will be greatly appreciated.
