Can someone explain the H1 and HUMVEE 4x4 system to me?
 

How does it work? I know the 2 and 3 well, but I have almsot no knowledge of the real things, I usually reference the HUMMER site, but they don't have the H1's information on there any longer.

How do the differntials work on the HUMVEE and H1

Do they all have front and rear lockers?

Are all H1's 4x4 system built the same? do they all have the same equipment, differentials, and abilities?
