Replacement Options
Because of the "weak" design, The AX-5 shouldn't be mounted behind any other motor besides the 4 Cylinder. Even behind the 4 Cylinder. It is still known to fail offroad. The most common swap with a 2.5L I-4 & AX-5 setup is a complete drivetrain swapout. Usually with the 4.0L I-6, AX-15 and NP231 combo. The reason to use the NP231 from the AX-15 is the 23 spline input shaft.
