I have a Whirlpool washer that quit spinning/agitating last night. It
still fills with water and still makes a noise like it's trying to
spin/agitate, but it sounds like a gear or something is out of line
and the motor/gear is just lightly touching the gear to actually move
the tub and center post thing.

Does anyone have any suggestions of what the issue might be? Is it an
easy repair for a homeowner? Do you have specific part #'s and where I
could buy sucha part? I'm fairly mechanically inclined so I'd like
to try to repair myself instead of paying someone else a $100 to
repair a $400 machine.
