Yep.
. and I hope you are talking about the rear axle as in the HOUSING. The carrier is part of the diff. its what your ring gear bolts to.
But to answer your question No It wont work. Its too narrow for one, plus its got spring perches on it for those leaf springs, and maybe you have never look under your 4runner but it doesnt have leaf springs. And cutting all the stock mounts off and welding them on a new axle would be a complete waste of time. It would be easier to design you own 3 link the would work better anyways
