In the wheel to wheel kit I had, it was mentioned that the tool needed lube every 3rd nut, but I did it on every one, this was after the second one gave me trouble for not doing it (spun). Also I would strongly advise to not use a impact tool. the instruction called for I believe 6 full turns after snug, so I marked my socket with a green line and followed to a t, torque was right on.
