Bet thats the culprit, try just blocking the line after the switch (under hood, on firewall, just below drivers wiper)and see if the loss of power goes away (4wd will too). U can replace the lines, but I would get the real hubs. There is something reassuring about turning to "lock", and knowing it's gonna work! <img src="/forums/images/graemlins/cheers.gif" alt="" />
