Just curious, where did you get those specs from? Both the owners manual and the service manual list a different fluid weight and mopar part number. They list 5126035, which is 75W-85 weight oil. They also state that if you are not using mopar fluid, any 80W-90 GL-5/MIL-2105-E Synthetic Axle fluid can be used.
I went with Valvoline Synthetic 80W-90, which is only a synthetic blend, but it meets the Military and API specs listed in the factory manuals. I'm hoping to procure an LSD in the next few months (fingers crossed) and rebuild my original rear end using that. This replacement rear end will hopefully only be used for a short time and then it comes back out, so I'm not too worried about the fluid.
