    If the full time drive allows the front tires to spin at thier own rate until they are slower than the rears in which case they begin pulling. Then why would there be additional wear and tear on the truck?

    I have a 73 k5- The hubs have no visible locking mechanisms so I assume it is full time 4wd? (It went from a farm house straight to garage for tear down)What advantages or dis to each?

    in non-loc positions the fornt and rear differentiate to with each othjer yes, but in either of the two loc positions the axles are locked in and spin the same RPMs

    good luck

    I think there is more bais to the front , so the front
    will be pulling just a little more then the back-end pushing. Also look at oem tire presusre front vs. rear,
    as well as front and rear diff. ratios. You got to look at the whole picture, not just the NP 203.

    The NP203 has an open differential in it which is biased towards which ever axle has the least traction/resistance. It isnt biased more towards the front. I like the idea of keeping the all wheel drive for winter driving but would like to see a limited slip conversion for the 203 to help with traction.

    But for offroad use a used NP205 would be a better tcase and cost about the same as a full shaft part time conversion for a NP203.
