I have a '74 k-10 and i assume that it has the NP 203 and it has solid hubs, but its only in lock that all 4 have power right, in just low and high it is just having to push the axle, but the axle is not receiving power right, i was told by some that it was a form of on demand 4x4 can anyone clarify?

thanks

With a 203 you have a "differential" in the transfer case. It sends power to the easiest axle to turn, which is usually the front. It is not "on demand" 4wd, as it will not turn both axles, unless it is in "loc".
