VSC light comes on shifting into 4H and front end feels like it’s binding up/dragging

Help! No Codes and truck is perfect in 2WD. Truck seems to fully engage in 4 wheel drive both H and L. (no flashing 4 wheel light) but VSC light comes on immediately shifting into H (after turning dial to 4H and before flashing 4wd light goes solid) and when driving it feels like the front end is all bound up/dragging and stiffer as I go especially if turning at all. I have tried disabling the VSC, TRAC and auto LSD. This also seems to all work in 2WD but in 4H I don’t seem able to disable the Auto LSD. One more clue, to disengage 4wd I have to stop and back up a ways and then go forward again to complete the shift to 2WD and then no more VSC light. Any thoughts are welcome! Dealer had no ideas.Thanks in advance!

 

Follow up. I installed a new front differential actuator and problems solved. Shifts into and out of 4H smoother now but more importantly the binding/dragging does not occur and it feels like it normally did when the 4H is engaged. I still am not sure what was causing that but hopefully this might help someone in the future
