Switching off ELSD

According to the service manual the locking differentials work using oil pressure. There is a solenoid that is switched off to release this pressure when the ABS brakes are applied. We wonder if it would be possible to create some dash switches that can activate the solenoid so that one can have an open differential whenever one wants. Maybe the clutch packs would last longer and maybe the fuel economy could be increased a few percent. For most driving situations, the AWD is not needed. I bet it wouldnt be hard to wire so that the computer doesnt even know that the solenoid is being activitated (like a relay). This would no doubt void warranty, but maybe in a few years after the warranty is gone it might be worth looking into.

Later Edit: I bet its the transfer case that eats up the mpg's and not so much the axles. Sitll, I miss being able to have 2 wd when 4 wd is not needed.

I hear ya on that one. It would be very nice to be able to switch on and off whenever you wanted to. I imagine the wiring would be a nightmare. And can you imagine all the codes that would be tripped?? dayuum
