Power Steer Gear Removal

I am removing the power steering gear. I did not buy it with the Pitman arm because I am not having an issue with mine. My question is how do I remove the pitman arm nut? It looks to be 1.25 or 1.5 inch nut. Do I need a socket and breaker arm? Should I buy a pitman are and just pull the whole thing? The service manual indicates 120 ft lbs of torque so socket or box wrench is the only way to go I would say.
