I feel the vibration in the seat of my pants, I see the other seat shake. But I don't feel it in the steering wheel as much, I don't feel it when I put my hand on the center console?

So crazy question, is this vibe a result of poor seat base design to handle the stiffer frame ride?

Is this crazy speak? I know I'm grasping since Ford is out to lunch on this.

 

I guess the general rule of thumb is if you feel vibration on the seat of your pants it's the rear end of the truck, if you feel the vibration on the steering wheel it's coming from the front.

 

I've noticed the same thing. I look over at the passenger seat (empty) and see the seat back and headrest shaking like a spaz.
I'm going to check some of the mounting bolts for tightness in morning.
