First, Remove the wheel
then remove 2 or 3 little clips that hold the hub onto the rotor
Pull the hub off, it shouldn't be hard, neither of my auto hubs were that hard, just give it a wiggle as you pull
then remove the "C" Clip (be careful it can go flying)
Next, remove the little grooved washer
then, a bigger ring (I can't remember what it's called)
Then it should look something like this:



When you get to this point, get a magnet, because there is a little square pin that sits in the groove(it's right where the bright spot is from the flash, so it's hard to see).
You need to pull it out, sometimes it helps to move the spindle nut back and forth a little by hand (if you can). If you can't get the little pin out, you can drive it through just a little bit and it will free up the spindle nut, but you risk breaking the pin.
Once you get the little pin out you can usually get the spindle nut off by hand(if not you'll need a 2 3/8 spindle nut socket).

After that you should pull out the wheel bearing and set it someplace safe, or replace it.

Then you should be able to pull the rotor off, then swap out the wheel bearings and seal(the seal is on the back of the rotor, you will probably need a new seal, $6.99 at Autozone)

I may be forgetting something, but this should be close enough to get the job done

I used my 2 3/8 Hub nut socket to try to hammer it in evenly, but yeah a hammer will work just hammer in a star pattern if you don't have anything else

I set them down gently and center them as best I can then lightly tap them in with a rubber mallet.

Hub nut socket is a good idea too though.

I used a big piece of a old sledge handle, whatever you use , you want it to make sure it is softer than the object you are hitting so not to damage it.

Thats a good point, I forgot to mention that I layed a shop towel over the seal when I hit on it with the hub nut socket
