like Jerry and Larry mentioned, could be the movement in the bushings you're seeing, or it could be in the hub. which could mean the bearing is bad, or the hub is worn, or both.
You mentioned that it clicks. I've never heard a bad wheel bearing click, but I've heard bad CV's do that. do you notice it doing it more when you turn right or left? if so, I'd bet it's a CV starting to get a little angry.
as for the wheel bearings, you can do them yourself, it requires a big hammer, a punch, or an air hammer. you'll need a good sized snap ring plier, a vice (most likely), lots of penetrating oil and patience.
good luck!
