I'm not sure. The vibration seems to be some sort of harmonic resonance type of response, and so I think it's a function of the pier itself.

Yes, the piles are short, and could be longer. It all seems rock solid at the base though, so I don't think this is the issue. Hesitant to weld because I like the option of disassembly.
Longer gussets might do the trick.

After removing the tek screws I used a pipe wrench to rotate the pile, and with upward pressure as I turned it moved quite easily.
