What you're saying would make sense if the knuckle were jammed tight up against the axle beam. If that were the case, you'd already have a problem of the steering being jammed.
At this point I'm pretty much convinced this is just an old fish story. If I overtighten my lugs that somehow make the wheel bearing stiff and give me bad fuel economy?
We do at least 5 sets of these joints per week and i have seen it many times screwed up by other technicians. I've explained in the best way that i can. The only other way i can show you is first had and that is impossible.
Next time you do a set of these, really crank on the castle nut for the lower ball joint, then try to move the knuckle back and forth. Then, torque it to proper spec (setting the joints each time), and you will be able to feel a clear difference in turning force needed to move the knuckle back and forth.

i drove the truck today and noticed a humming noise coming from the front while driving. sounds kinda like big mud tires but as soon as i touch the brakes it stops immediately. any ideas?
I tightened them snug and to seat the bearings and then loosened them until all the slack was out of the hub but that was about it I also did repack them .
bearings were fine it was the dust shield rubbing. it broke away from on of its 3 bolts
