Please don't use the auto-lock hubs with a solid front diff; I just don't foresee good things happening. Get manuals. You'd pretty much be asking for full time locked together front and rear diffs and wheels, if the rear was locked as well. Steering would blow goats. But if you needed that kind of traction, just beware. I'd like to have a selectable front for the wheeling we do in AZ, as in an ARB, but the money tree is out of season, apparently.
