My shake had a death grip bearing seat initially, but was solved with a simple toss in the freezer.
Days ago, I unscrewed it to clean the bearing
It stayed on the other half of the yoyo, but I doubted anything would change. I popped it in the freezer, and tried taking it out, to no avail
FF 3 days later, I’ve spent a solid hour wiggling it with pliers, and have tried every increment of one in the freezer from 5-15 min multiple times.
