Unless retaining a splined part, bolts on power shafts generally loosen being turned in the direction of normal rotation so I would first check the service manual, then look for any arrows on the casting, then set my torque wrench for about 5lbs over the torque spec and while holding the hub, try loosening in the direction of rotation. If it does not move or gets tighter, go the other way. I looked for videos on this but had no luck.
