Prelude tire clicking?

i drive a 94 prelude si with a 94 prelude VTEC engine in it... wehn i drive my front driverside tire makes a clicking sound; you can hear it best when im moving slow because when i move faster the clicking happens so fast its hard to hear. It doesnt happen only when i turn and does not amplify or change when i turn. So i dont think its the CV joint. I think its the wheel bearing. Someone on a forum said to just tigten the screws in the wheel bearing and it will stop... I dont see any screws when i pull teh tire off and poke around though... where are these screws he spoke of... or do i just need to replace my wheen bearing? or is it something else? thanks
