Finally got it with Chrome.
That's bad!
After you've checked all the bolts and computer connections, and it's still bad I'd e-mail vid to Tech Support and then call.
I think it was Brady who said that left bearing is supposed to be a loose fit and he told someone to put a couple drops of 3-in-1 on it to see if it helped at all.
Mine has between a 1/16-1/32" of play in Z and Y, but ZIP in X. Also your bearing looks much further out than mine, but mine's 15 months old and not sure if it's changed in specs.
Had a similar thing happen when a keyboard, USB hub, and then a mouse went bad(sounded like a hard stop in the middle of my board when C3'ing--Just stopped moving entirely, with accompanied hard stop grinding noise) swapped out components and rebooted and all was fine.
Good luck
