reading about the axels in my truck i found that they are the 8.8 with 31 spline, 06 fx4 level 2, and i read a disc brake upgrade about a swap from an explorer with an 8.8 31 spline to the rangers 8.8 28 spline, but needing modifications. So the question im asking is if the explorer and fx4 31 spline 8.8 have the same bolt up for the rear discs and if they can be swaped without modifing them.
