Don't know. Here's another question, along those lines. With a locker up front, (any design, detroit, spooled etc.) is the "shift-on-the-fly" affected? When shifting, will/is there any grindning in the axle tube until the axles have meshed? If so, how long will the stock axle components be able to take such abuse? I'm guessing that with an open or LS diff there's some play that allows a"soft" engage.
With a locker up front, won't that engage be Hard?
