REAR WHEEL HUB ASSEMBLY REMOVAL

1999 BMW 323

Drive Train Axles Bearings problem
1999 BMW 323 6 cyl Two Wheel Drive Automatic 83000 miles

I am trying to remove the drivers side rear wheel hub assembly, I got as far as removing the center nut, But the hub itself won't budge, What do I need to do next? Is there a circlip somewhere thats holding it in place or do I just need a gear puller? I don't want to go any further until im sure whats next. Do you have instructions and drawings? And the reason i'm removing this is I isolated the humming noise to this wheel so I wan to check the hub bearing. So pls help.
