Aggitator is making a grinding noise
 

When aggitating is makes a loud grinding sound. When the machine is just spinning it works great. I was wondering if the aggitator is one piece or can you take it apart. When i take the aggitator out and then run the washer the grinding noise is gone.

Here is the exploded view of your machine, for the agitator and parts.
