My 2004 f250 2wd has a vibration on acceleration only. No noise

What is your question?

Vibration gets less while cruising, but gets bad again when you push the accelerator. No noise is heard at any time. 5.4 L V8

What makes this problem better or worse?

Vibration decreased when cruising but gets bad again when accelerator is pushed

How long has your 2004 Ford F-250 Super Duty had this problem?

A few weeks
