BCM replacement for 4 wheel drive issue ?

Does the ESOF Motor run when shifting into / out of 4 wheel drive?
Does the Transfer Case shift?
Do the front Half Shafts turn?
Do the IWE's lock?

That's so far down the list that I wouldn't even consider it just yet. Always go for the basics / easy stuff first. I'm sure replacing the truck would fix it too!
