2001 Pontiac Montana clicking coming from wheel as it spins

I can hear a clicking type noise coming from what sounds to be the front driver's side wheel. It does it from the second that the wheel starts to move. I know that a symptom of the CV joint going bad is clicking as you turn. That's not what it's doing. It clicks the moment it starts to turn and never stops until the van is no longer moving. I'll of course take it in to get it checked, but I would love to hear somebody elses opinion before I do that, so I can have a clue if I'm being misled. Thanks!
