No tips as the bearings are roller bearings with no race to remove. There is a tool that the auto parts stores will "rent or lend" when you need one, that goes on the end of a slide hammer. Sometimes you can get them out without using the tool but its so much easier with one, you should try to find a parts store that lends one out.
One thing to look out for is worn out axles where it rides on the outer wheel bearing. If the axle looks all grey and rough looking or with any grooves showing where the bearing rides on it then the axle might need replacing.
I use a piece of emery cloth (sandpaper?) to clean up the end where the bearing rides and then check to see how the axle cleans up. Even if the axle looks good, I still give it a quick clean up with the emery cloth before I put the axle back in the housing.

This is the tool that goes on the end of a slide hammer and slips in behind the axle bearing then the slide hammer will pop the old bearing out from behind. There's probably a video on Utube of someone doing the bearing removal but its pretty much self explaining.
