We had only one hummer on our lot it had been sitting for almost 3 months and they needed to get rid of it so I got a deal on it. Also at the time I bought it I was under the impression that they all had locking rear diffs. Since on the 4wd switch there is a damn picture of a lock on the button IMO its stupid to even make a Hummer that doesnt have a locker. Is that enough explination for ya
