2003 F53 runs smoother above 70 MPH
Well I guess I'm going to get blasted on here for this post but here goes anyway: My 2003 F53 smooths out and runs real nice above 70 MPH. At 65 there's some shake. At 78 it rides like a luxury coach....

I had something similar with my 06. I had a slight vibration at medium speeds. Tried balancing tires. I even had Ford check the drive shaft.
One day I was talking to an " Old Timer " ( like I am ) He says. It sounds like you blew a plug. Then he asked if I can feel it more when on a pull. A slight hill. Yes.
He was right, one of my plugs was bad. Had it replaced, problem solved.
