How hard are they to change?
I know the fronts a press in, but how 'bout the rears?(they come as a bearing/hub set)

 

You remove the wheel, disconnect the brakes, remove the rotor, and take off the spindle nut from the hub (along with the spindle washer) thats under the little cap and you can just pull the hub assembly off. Installation is reverse of removal... no biggie, doesn't require a press or anything. The hub assembly itself IS the wheel bearing, if you get what I mean...
