If there is noise -you have cavitation, bearing problems, or something dragging. How does the motor sound without the pump section installed? Run the motor and shake it around a little to try and reproduce the noise. That will tell you if the motor section is OK. Chances are that you have too much clearance in the impeller bearings which will cause a chatter.

When you remove the pump -Can you see any scoring which would indicate that the impeller is dragging?
