The RCE brake duct blocks that ball joint cross bolt, so you are back to removing almost everything under the sun to get to it.
I don't have Cory's monster impact gun, but my 500 or so ft/lb one broke the axle nut loose no problem. It wasn't powerful enough to do the front aft control arm nut though which Cory's spun right off.
I ended up wedging something between the driver's seat and the brake pedal to torque it. I'm not sure I would want any weight on that wheel bearing without that nut being property tight. Might also skew torque reading.
