On my way to work this morning and this noise started. No chance to look at things in the dark. Maybe you guys can point me in the right direction so I can check things after work? Possibly the radiator fan hitting something?

 
Doesn't sound like anything too serious. Sounds like metal hitting metal, but something hollow. Like maybe something hitting on the exhaust pipe.
 
Sounds like it is coming from the front end. Would U-joints/axle U-joints make this noise at all? Almost sounds like something is flapping in the wind and it's only intermittent.
