Vitamix blender disassembly and checking the bearings

[@stpfarms]

Same issue… you ever get this fixed?

I went through this while process and after reassembling it, the problem hasn't arisen since.
My best guess is that the grub screw that holds the black hub was a bit loose (it's the screw I end up tightening with an Allen wrench).

Thanks. This was very helpful.
