We don't know enough about the Nissan D44, it could have a different axle shaft diameter and/or spline count than the ones used in Jeeps, Isuzus, etc. so the aftermarket may or may not have anything off-the-shelf for the new Nissan D44

It definitely has a different wheel lug pattern than the H233B (still 6-lug, but a smaller bolt circle), so anyone swapping an 05 D44 under the back would almost certainly be looking to put a solid axle up front as well. I don't know if there are even front D44 applications with the same lug pattern used on the 05 Xterra and Frontier to match offhand.
