Ahhhhhhh read that wrong, I have been researching front axles too much, didn't even thinkof the factory D44 rear.
Thought you had to be talking about the "other rig" since you were debating SASing the Rodeo.
As for the SAS or ARB... I would go SAS instead of the ARB's first. Then you won't have to buy/setup 3 lockers, and maybe save you in front end breakage $ as well.
