Does anyone else feel a shudder around 40mph? My last truck '12 F-150 Screw 5.0 had a vibration but at highway speeds. My new truck seems to be fine at highway speed but I feel a shudder a 40mph. To fix the issue in my 2012 they replaced the drive shaft and then it was smooth as silk, I am wondering if this might still be the issue with me 2014.
