so when i lock the 4x4 in i can hear it lock in the transmission but i will not pull. my front axle will spin but the front tires will not turn. the truck has automatic locking hubs but they are not locking in. they are not moving or nothing. i think it is something in my front transfer case. i know your not suppose to lock the 4x4 in while the truck is in gear but i did it to see if it would make a noise and it didnt so i need someone that actually knows what they are talking about to tell me what is wrong so that i can have it fixed.. thanks
