* Axle Housing: The axle housings themselves might have different dimensions and mounting points.
* Differential Gear Ratio: Gas and diesel engines have different power outputs and torque curves. The 1986 gas engine would likely have a different optimal gear ratio than the 1995 diesel. A mismatch could lead to poor performance, drivetrain strain, or premature wear.
* Brake Systems: Brake components, including backing plates, calipers, and rotors, are often different between model years and engine types.
* Spring Perches and Mounting: The spring perches on the axle housing might be positioned differently. The 1995 truck likely uses heavier-duty springs to handle the diesel's torque.
While some components *might* be interchangeable (like certain brake parts, depending on the specific options), a direct swap of the entire rear end assembly is highly unlikely without significant modifications. You'd likely run into incompatibility issues with mounting, braking, and possibly even the driveshaft.
It's best to stick with a rear end from a similar year and engine type for a straightforward swap. Consult a parts catalog or a Ford truck parts specialist to confirm compatibility.
