Are you first of all doing this with the wheel on and the vehicle on the ground? It is counterclockwise, at least all the vehicles ive ever done this to is, to loosen so its regular thread, are you sure the cotter pin is removed from it and its not snapped off in it? Soak it with penetrating oil also if possible heat it up with a torch, but make sure everything is disconnected first. And only use it if the penetrating oil and a longer bar doesn't work.
Im surprised your 550 ftlb impact cant loosen it!
Usually they loosen right up for me with a 3 foot breaker bar.
Check the threads just in case it is clockwise thread, put a needle on the threads and go around it counter clockwise, if it loosens then its a regular thread, if it tightens then its opposite threaded.
