There is indeed 2 sets of snubber pads.
First set is not too bad to get to. They are.Part #
285744. I had already replaced these three, they were completely worn. The vibration improved but it wasn't completely tamed and gradually got worse.
Here is installation instruction for first set:

285219. Looking at them as best I could, they appeared to be in good shape.
What I did to prove whether these were the culprit was to cut 3 plastic strips from an old vertical blind. It's 0.5mm thick. So I figured it might take up some slack. I was able to pry up similar to the other set and slide the plastic strips in but you could never change them this way. Sure enough the washer spin cycle has calmed down. The current snubbers must have worn enough to become ineffective so don't be fooled by the thickness of them.
Here are instructions for the more difficult snubbers (would be easy to change both sets when changing this set):
