But the entire '90 XJ Cherokee axle housing will bolt in to the Eagle. The spring perches are in the same locations as the Eagle. The shock absorber mounts are different, though. One side lines up perfectly with the Eagle's shock configuration, and one side is on the wrong side of the axle tube(can't recall which side). It could be cut off with a torch and welded back on in the correct position for the Eagle. Also, remember that the rear axle gear ratio must match the front axle ratio for a 4x4.
