Why don't you just contact VPI with your issue . They have excellent customer support. They e-mailed me with an answer to my question on Sunday morning. Can't get better than that.
I'm surprised to hear about the factory-applied grease as to my understanding VPI uses Super Lube to lubricate their inverted bearings. At least that's what they sell and recommend.
Did the grease you purchased from Amazon solve the problem?
A light tap with a drill press was all that was required. Obviously nothing I would be willing to do myself, even if I had a shop or access to one. Spins effortlessly and sounds amazing.
