Dumb Stock Hub Question
A little embarassing to ask but, I have not been able to find it out through other methods so....
Which way do you turn the stock locking hub to be free? Will driving with the hubs in the locked position decrease mpg?
My stock hubs no longer have the markings. I could not find anything through google. My friends centurion turns right to be free. The haynes book I have doesn't say and the picture is very hard to read with the free/lock positions. It looked like free was turn the hub left in the picture.
Thanks in advance all!

Clockwise - Lock
Counterclockwise - Auto (unlocked)
It would stand to reason that if your hubs are locked in you're going to take a small hit to your gas mileage as you have more moving parts to get up to speed every time you accelerate.... it may be minimal, but it would not be zero.

You can always jack up a wheel, put the hub to what you think 'lock' is, and see if the axle half-shaft spins. That way, you both know the position and that the hub itself is working.

It's pretty easy to reach around the tire and just try to turn the axle shaft and check. Clockwise is lock, Counter clockwise is unlock, but you might have to wiggle the axle a bit to get it to unlock. I have to do that on mine sometimes. If you can't turn the axle by hand, then it's locked.
I ran mine locked in last winter heading to Colorado, and when we stopped for fuel I unlocked it. I was getting about 12 mpg with them locked and about 14 with them unlocked. This was driving across the midwest, before the mountains. Your mileage may vary since that was all highway driving and it was cold out.

Just remember that the clockwise/counterclockwise applies to both hubs as you are crouched down looking at them.
