The difference is in the pitman arm, location of the pitman arm and the attachment of the pitman arm. The 2wd pitman arm fits on a splined shaft and is held on by a large nut. The 2wd pitman arm points to the rear when the box is centered. On the 4wd the pitman arm is clamped to the splined shaft and points outward to the left with the box centered.
