If you mean the gearbox, contrary to amateur opinion, nylon is probably a superior material to the cheap metal ones they replaced.
Because their mixers are still made in the US, labor saving cuts are much more worthwhile to them than materials.
(Their non-mixer offshored lineup is overpriced crap though).
A good example is the removal of the spring & washer used to secure the attachments: they are only a few cents of material, but they greatly increase the life expectancy of the mixer. Now you'll have to get those for $10-$20 from a 3rd party...
Oops. Do they? I ripped mine off years ago. It makes a bit more clatter at low speeds but I haven't noticed any damage.
