Hubs,maybe?Is the 4WD ingaged using the vaccum off your engine,also may be your problem,that happened to me on a Blazer I use to own.Try listening for hissing noises under your hood or close to your front drive.I may be wrong,but I think I understand that the newer Rangers have vaccum actuated 4WD
Yes, reads like the Pulse vacuum hub system is not working

General consensus is to scrape any Ford "auto hubs" in favor of manual hubs, "on the fly" 4 wheel drive just isn't needed that much IMO, getting out and manually locking or unlocking is just not that big a deal.
Most discover their auto hubs are not working when they need 4 wheel drive, lol, like most things you don't miss it until you need it.
Even rebuilt auto hubs will most likely fail again and, of course, only when you need them.
Manual hubs are not bullet-proof but tend to last much much longer, and work when you need them.
