No need to remove the hub.
Do NOT remove the axle nut with the car on the ground, as that will damage the wheel bearing.
The axle nut is 32 mm staked nut. Once you unstake it, it will turn quite easily with a long wrench. It's only 206 Nm... If you still have trouble with it, try a long pipe on the wrench -- it has never failed me.
The axle nut MUST be discarded after removal. Use a new axle nut ever time.
