O.K. Here is my first newb ? I am taking my rig off road for the first time this weekend. So I needed to know when to use the locker & if there are any speed restriction. I have used the search option, but I didn't find what I was looking for. I don't really know what my 2WD is capable of, so if any other two wheel guys can send me some pics, I would be very gratefull.
