I have a whirlpool washer WTW4800X04. It makes a whirring noise when spinning. Whether during the rinse or spin cycle. It has gotten louder overtime. If I open the washer and spin the drum by hand, it seems to spin very easy. Easier than I think it should. If I give it one turn it will continue to spin on its own. Other than the noise and the excessive spinning it operates fine. What could be my issue here? Thank you for your help in advance.
