Best way to check a wheel bearing is to crouch down, grasp the tyre and push/pull the wheel. If its a wheel bearing you should easy see/feel some play.
A cv joint can wear out without a boot being split, it'd be worth pulling apart your outer cv joints and checking them for any damage, if all is well clean it up, whack new grease in and put it back together. It is very rare for inner joints to make a noise, because of their design they seem to last longer than the outer joints.
