F150 4X4 PROBLEM

2005 Ford F-150 • 5.4L V8 4WD Automatic • 116,000 miles

I have a 2005 f150 with the electronic 4x4 switch for the 4h and 4l. At a sit still, the 4x4 will not lock in. Going at very low speeds, it will lock in but sometimes it pops back into 2 wheel drive after some distance. At speeds around 10-15mph, I turn it into 4x4 and can hear it click over but then hear a grinding noise coming from the front. Turn it back into 2 wheel drive, the sound goes away. Just yesturday I attempted to pull a car from a ditch, I was in 4x4 at the time of putting tension on the tow rope and as soon as I started pulling, it popped out. Any suggestions?

Scan for codes and check the motor on tcase to see if it is engaging 4wd all the way. It might be internal to tcase though
