My AMS wasn't working properly; it was jamming regularly, and I kept hearing grinding noises. I disassembled it, and would you look at that! Fortunately, there is a 3D model for replacement on Makerworld that works perfectly (this one, by the way:https://makerworld.com/en/models/1659680-bearing-cover-for-ams-internal-hub-unit#profileId-1755486).

So, thank you so much to Sander. If your AMS starts making grinding noises, it might be worth it to take it apart.
