I replaced the whole impeller assembly and what a difference...there was quite a bit of play. It's dead quiet now.
FWIW, the bearing kit alone would not have done it. I slid the old impeller on the new shaft and it still had more play than the new assembly.
I also put a criticool powerplant on the thing....should extend the life of the impeller.
I also took the opportunity to pinesol my system and take a quick measurement of system flow (the 'time to fill a 2 liter bottle' method). I measured just over 2 L/m, which seems high for this rig (see sig). So much for accuracy.
Edit: I did some digging. ~1 Gal/min is about what this system should be seeing.
