So, I started noticing an almost grinding noise that would stop when I hit a bump, more like a something was dragging on the ground. On my way home today, I hit a bump, it started then I hit abonther bump and the whole front end started shimmying, when I slowed to pull over, it stopped. I also feel a vibration while the noise is happening. Any ideas what it could be?

 

Sorry, should mention I have a 2006 screw 5.4, for now anyways, I'm just about done with this money pit.
