I'd lock the hubs first and then shift into 4 wheel drive and then take off s-l-o-w-l-y and see how it feels. If it feels more difficult than normal to make sharp turns [and you get unusual feedback in your steering], then you ARE in 4 wheel drive...Feel is important with 4X4's--- you can tell if your in 2WD or 4WD after getting used to a vehicle. Best advice is get the Owner's Manual or call a Ford dealership. Good luck with it.
