2000 chevy malibu wheel hub replacement

I have done all I can to try to take the wheel hub off. I have taken all 3 bolts off and have taken off the axle nut. what do I have to do to take the hub off now. Thats all the book told me that I have to do. I have tried to pull it off but still does not come out. is there something that Im missing. Please help!!!!:banghead:

This part was a two step process for me. 1. break it free from the axle with a wheel puller, 2. attach a slide hammer to the hub and pull until it comes off of the knuckle. You can kind of combine these two depending on which axle puller kit you end up renting/finding.
