Once you remove the large hub nut the hub and bearing should slide off using your fingers, if it sticks GENTLY tap it back on and repeat, trying not to let it rock to one side. I use fingers to pull the hub and thumbs on the end of the stub axle to keep it square.
You‘ll need access to a press to remove the bearing from the hub and likely to replace it unless you have a large vice in your garage. Most garages will remove/refit bearings for a small charge.
