Ever since I locked my hubs into 4wd I have a bad vibration at around 40 mph and at idle it shakes intermittently. Need some help! F250 5.4l v8 gas

Check the vacuum lines and such for locking the 4x4 system, you may just have a slight vacuum leak. As for the vibration is it in the truck or the front end??
