You have an open diff, all titans have them. You might have abls, which will apply the brakes to the wheel that is spinning, which in turn sends the power to the wheel with traction. The easiest way to find out is to get in grass or dirt and spin your tires if you get a slip light on the left side of your instrument panel than you have abls. I don't know if all titans have abls or not.tre5 said:
