Thanks for all the responses. So far I am leaning on just an ARB up front and leaving the LSD in the rear.
But it leads me to another question:
Currently when I put the truck in 4WD one front wheel will drive...I don't know how to determine which of the two become a drive wheel, maybe someone can answer that.
If I had an ARB up front, when I put the truck in 4WD without engaging the ARB, I would get no front drive wheel action at all, unless I engage the ARB then I get both, correct?
