98 WS6 Posi Unit?
If it's a SLP car,the SLP sheet would indicate if they put a different posi in it as an option after it left the factory and was in their facility.
Torsens don't 'wear-out' but have 3 flaws/weak points. 1.the bolts holding the unit together break. 2.the bolts holding the unit together loosen/back-out and then break when they hit something internally in the rearend housing. 3.the flange holding the internal gearset in breaks at its' weak rib points.
