So, I have been having this sound coming from the front right wheel. I thought it was the wheel bearing but it doesn't really sound like it too much to me. I thought to maybe grease the fittings as well but I wanted to see if anyone else had experienced this problem before. Thanks! (Skip to the end for a better sound).

 

It's probably fixed by now, but it sounds like a knot on the inside of the tire, rubbing the frame. I've had that.
