I sure feel like an idiot. The problem was simple as re-torquing the bolts. All I did was loosen the bolts a bit, and re-torque at 88lbs-ft. I did this on Sunday and after driving for awhile, I didn't feel any vibration. I wasn't quite sure but after driving for two more days, I am pretty sure the vibration has gone away.
I mean these people are paid but if they can't get something as basic as torquing, I don't know what to say.
