UR nutz if you think is costs 2 or 3 MPG to spin the front CV shafts and the spider gears.
Yes, it HAS to take SOME power but NO WAY is it believable it would be that much.
The auto companies take drastic measures to increase mileage by even 1/10 of a MPG, and there's NO WAY an "easy" 2 or 3 MPG increase would be overlooked!
Why not put the blame for poor mileage where it truly rests... the bottom line with mileage in new vehicles is that it takes LOTS of extra fuel to clean up the emissions to meet government mandates. (As ludicrous as that sounds!)

You will notice the 4X4 has a mileage penalty of ONE MPG on the highway, even with it's added weight of the transfer case and front driving axle.
If there is only ONE mpg difference between a similar 2WD and 4WD pickup to begin with HOW could lockout hubs save 2-3 MPG, making the 4WD with hubs 1 or 2 MPG MORE efficent than it's 2WD cousin???
