Check the actuators in the diffs[front]you may have frayed wire.The other thing would be to check the oil level in case..Are you able to get the case into neutral????

I Have the electric controlled Case with just 2wd High 4wd High And 4wd low and Automatic transmission so only neutral is on the transmission.Just three buttons with light on it for the case.But it could be possible low gear oil on the transfer case i will look at that in the morning.

Any other suggestions

For neutral IIRC you put the tranny in neutral and then you press and hold 2hi and 4Lo and the same time. The push button is also shift on the fly, so try it while rolling a little with it in gear and see if it will go in 4hi. You have to be in 4hi before it will go into 4lo and it must be stopped and in neutral to go to 4lo.

Have try to put in in neutral and push 2hi and 4lo at same time but nothing happened except the 4lo blinks but no sounds come from transfer case and i have the tranny in neutral.

But with tranny in neutral and push 4hi it sounds like it do it and when i drive a little bit it comes a sound that it do not hit in lock but all the time 4hi light on the knob blink and same for 4lo.

If i have tranny in park and push 4hi nothing happened except 4hi blink no sound from case.

Same if i am driving slowly and push 4hi nothing happened

Ok, he's not as good in English as i am

If you press 4Hi light starts blinking, then you put it in drive (hoping for it to lock in 4wd) and then it grinds.... like grinding gears in a manual transmission...

anyone know what it could be... is it the transfer case or the actuator of the front wheel drive ???

Does the truck sit outside all the time? What kind of temps is it there right now. I have seen some during the winter here freeze up and not completly engage. Other than that it sounds like the actuator is not fully engaging.

temps here now are around 13-16°c so no snow or no frost....
