Jack the car up and rock the tire back and forth, grabbing it at the top and bottom not the sides. If it has excessive play its a wheel bearing. Rocking it as if you are turning isn't going to necessarily point you towards a bad wheel bearing, its more than likely going to determine tie rods being wore or your rack is bad. But since you said you have a skunk2 camber kit, take the A arm off and check the bushings. They are probably wore. I've learned that from experience. I have the same problem now. I also replaced the ball joint and it still did the samething. I'd check the bushings before possibly wasting $43 on a balljoint.
