Just recently I notice a clicking noise when the car is rolling under 5 mph. The slower I go, the slower the sound gets. I can't really hear it when I'm going faster because of the road noise. I hear it from behind the drivers seat, but it doesn't sound like it's coming from the engine bay or the wheels. Does anyone know what this could be?

 

jack your car up, and roll each tire to see if it sounds like something is inbetween the wheel and tire. you will hear it roll around. it sould be the valve stem nut that has come off. i had the same noise, a loud clinking (sounds like a rock in the breaks) then just took it in and they fixed it for free

 

Well, It could be a rock in your tire, or it could be your CV joint going bad...check to see if your CV boot is torn.
