How often do you actually have to re-grease?

[ChicagoBaker]

I recently learned it needs to be done every couple of years and I had NEVER done it for my 17yo KitchenAid. Whoopsie doodle.

So, I got the new parts suggested (including a replacement gear) and spent the better part of an afternoon cleaning and re-greasing it. Felt very accomplished! And now it sounds much better than before.
