...Two things may help you decide. First, jack the rear in the air so both tires are off the ground. Put truck in neutral(be sure and put blocks in front!!) and spin the rear tires. If both tires spin the same way, you have a limited-slip axle. The second way...look inside the drivers door jamb for the axle codes. Most of the time Ford will use a Letter designation with the axle code to signify a vehicle has a "posi" rear end. Good luck....
