I don't know where to start looking it has a four shift and when you put it in four wheel drive like four low the truck gears done like it should so don't think its the transfer case and ideas would be very helpful thanks
 
maybe the hubs aren't locking? look in the owner's manual to see how the 4x4 system works. you may have a live front axel so the hubs are always locked. it may be the transfer case as there is a mechanism to engage the front drive-shaft.

then it may be in one of the hubs in front, if one is not working it will not go into 4x4 this is a common problem any time I had a problem with the front hubs I put a set of warn locking hubs on front some years you can, some you cannot. But first figure out if one hub or the other is not locking.
