I don't trust anything with the word "automatic" in it's name. I'm sure automatic hubs were designed for lazy slobs. Even though I'm new to the 4WD world, I still remember my much older and somewhat smarter brother switching from auto to manual on his Chevy, when I was still a young'n. You know what he said? "I'd rather switch'em myself, than sit in the truck and wonder". I don't trust anything...
