Mystery vibration

[rparker762]

So my 03 has a vibration that usually happens between 60 and 70 but sometimes starts earlier and ends earlier. Also Sometimes its really bad and sometimes not so bad. The wheels and tires are balanced and the truck is aligned to specs. Any thoughts? Stealership says they cant find anything wrong. Also, the truck pulls to the right slightly. Again, good alignment and it has done it with any wheel/tire combo I've had on it. My though might be the hub assembly but don't wanna start throwing money at it without a good place to start.

If it is properly aligned and pulls to the left then I'd check for brake drag. Possibly the left front wheel bearing. The alignment guy should have caught it.
