According to an information sheet for my Estate from the Ford dealership I bought it from it says it is a 3.92. I also assumed it had a limited slip differential in the rear and front. However I have all four wheels off the ground and I rotated one wheel on each axle and both times the wheels turned opposite of one another.

Another friend hazard a guess that it has an LSD but it has slack so it is acting like an open diff. Any identifiers on like the casing or anything that can let me know for sure please let me know. I though 3.92 open diff cars weren't a thing because another thread said 3.92 was for the 4 pot and 3.62 for the 6 pot 4x4 cars.

 

2.0 4x4 has 3.92 front and rear diffs. Rear diff has LSD, centre transfer box has LSD, front diff is open.

 

Ok so why is my rear wheels turning in the opposite direction? That's an indication of an open differential?
