RV Repair: How do I remove the hub, cap cotter, cotter pin

Question
I have a 1984 Rockwood pop-up (no brakes) and need to replace the bearings. I have removed the dust cap , cotter pin, nut and outer bearing. What is holding the rest of the hub from coming off the axel? I want to replace the rear bearing too.
                                    Thanks,

Answer
Tom, There shouldn't be anything else holding it on. It may be that the inner bearing is a sealed bearing and you will need to use a puller. Although I have never seen one with a sealed bearing. Try harder when you pull I guess. Sorry that I wasn't more help. Thanks, Bill
