This unit was working well then suddenly started making loud noises although it still washes the dishes. The noise is like a bearing whine/roar. I have removed most parts working my way down from inside the tub to the motor looking for debris. After removing each part I turn it on and so far the noise persists. Looking at the diagrams I think only the bearing remains so I figure that's where the noise is coming from - though I am unable to get the drain impeller off the motor shaft to look at the bearing. The chopper spring is bent as is the chopper blade - so I know something hard went thru there. I found a 3/4 inch screw loose inside. I'm pretty sure I should order the Drain and Wash Impeller Kit (AP3115180) and replace all those parts.

Three questions:

1) The photo of the kit shows what looks like a bearing but it doesn't list any bearing. Is the bearing included in the kit?

2) Do I also need to order the Pump Housing Centering Tool (AP2908817) to be able to install the kit?

3) Is there a non-destructive way to remove the drain impeller?

Thanks
