The bearings need to be pressed in with a hydrualic press. This is not something that you can do at home, unless you own a mechanics shop.
Your options are:
Take to an independant mechanic, cost me about 150 to have the drivers side replaced, with other people having about the same luck.
option two:
buy the new bearing (~$40-$50) and remove the old hub assembly by undoing the balljoint pinch bolt and tie rod ends, etc, take the entire hub assembly to a shop and they can press the old one out and new one in, then replace the assembly yourself.
You are probably looking at an hour of labor from the shop this way (unless they don't charge the full hour, since it doesn't take an hour)
