1300 miles, 5 weeks old. Vibration I can feel in the steering wheel and the floor under acceleration between 70-80mph or so. Ford has rebalanced (ground force) tires. Today, I picked the truck up after a new driveshaft install. Still the same issue...it only does this under load (acceleration) and stops when I let off the pedal. Trying to contact the dealership to see if they replaced anything else. Has anyone else had this issue? I've owned Ford trucks since 1982 but this is my first SD...Lariat 4WD PS.

The only thing remotely similar to this was a new 99 Mustang Cobra I owned that had a vibration issue (the vibe) which had a TSB. That may have been more related to the IRS but I can't remember.

Irritating I'm already piling up the service Dept days on a 5 week old truck.
