First, let me start by saying I appreciate your opinion. I'm not a seasoned "off-road" guy and thanks to the information you gave me earlier, I now understand it's not an "simple" swap. I bought this explorer as a family car but I would like to make it capable of having a bit more fun than oem. If I'm not mistaken, a limited slip differential, while not a locker would provide better traction than an open dif. When you said it won't make a difference did you mean that both wheels engaging vs one wheel engaging isn't "a difference"? I'm fully aware this gen of explorers are not the best for off roading and Im not expecting Raptor capabilities by swapping a diferential. However, I am hoping to increase its off road capabilities for any family outing (camping, fishing, etc). Thanks again, I appreciate the help.
