After googling the exact problem with my stand mixer I found a link to the this product (the exact part I needed for our model mixer). For 1/10th the cost of a new mixer, this piece and a youtube video later the mixer was fixed.
Perfect drop-in replacement

I have no idea why anyone would go through the effort of replacing the worm gear only when this assembly is perfect and cheaper.
Took more time to clean up the old grease than install.
