After each spin cycle, my Whirlpool washer makes a loud noise as it comes to a stop.

Hello ronpaul

So you do not hear anything abnormal during spinning itself?

Plug off the mains. You only have to check the inside after opening up, for the dampers to be in place, springs. This happens when the load is uneven and you have a big sheet in the washing. Normally the clockwise & anticlock wise turning of washer sorts this out, but towards the end of spin it does sometimes happen.
