i have the hub nut off, the caliper removed, nothing appears to be keeping it on there... i was told that nissan or infiniti ever made a one piece assembly, so the rotor should just come off. i will wait to hear from someone who knows before i go banging away on it to get it off.

rust is probably holding it on there. hit it with a rubber mallet to get it loose

I think u should consult a good mechanic. Or the dealer can help u with that.
