    I had my impeller bearings go out about two weeks ago so I replaced them. two days later it started getting loud again so I checked and there was some slop so I replaced both bearings once again. A couple days later it started to get loud AGAIN, what could possibly be wrong?? Am i doing something wrong when I replace them? Any help is greatly appreciated!

    One of my ultra vacs had a bent impeller that resulted in a vibration and an awful noise.

    I thought it could be something to that affect but when I replace the bearings the noise stops for a couple days...did yours do the same?

    Sounds like a out of balance impeller is ruining new bearings
