    possible positively pos.

    i have a question about traction control rear axles. i am hearing that traction control rear ends are locker type rear ends.i'm not sure about that, but are they posi units?,or does the plug in on top of the axle housing have to have power to have posi traction.is it full time pos.,or does it have to be powered up?or is it something differrent all together.salvage yards say that all traction control rears are posi.,if it is installed in an older model-non comp. controlled car is it going to have both wheels pulling,or like i was saying ,do you have to power it up,or just a single traction axle?

    First off traction control has nothing to do with your rear axle whatsoever, all traction control does is limit or reduce the throttle when the TCS is activated and the speed sensors detect wheel spin. The plug on top of the axle housing is a speed/ABS sensor that pics up signals from a reluctor ring on the carrier assembly. Your car has a limited slip diff. and will "lock up" when one wheel spins freely. To my knowledge the 98s have a standard spider gear differential that uses clutches for the limited slip and 99 and ups have a worm gear torsion differential that uses centrifugal springs to lock.
