Applications and Fitment

The NP231 transfer case was a popular choice across numerous vehicles, primarily from Jeep. Understanding the exact fitment for your vehicle is crucial. Common applications include:

  • Jeep Cherokee XJ (1987-2001): A very common application, often found with 21-spline or 23-spline input shafts.
  • Jeep Wrangler YJ (1987-1995): Another core application, known for its robustness in off-road settings.

When you’re ready to purchase, make sure you have your vehicle’s year, make, model, engine size, and original transfer case tag information handy.

Installation Notes

While installing an NP231 transfer case can be a DIY project for experienced mechanics, we generally recommend professional installation. Proper installation is key to ensuring the longevity and optimal performance of your new unit. Key considerations include:

  • Fluid Type and Capacity: Use the manufacturer-recommended transfer case fluid and ensure it’s filled to the correct level.
  • Gasket and Seal Surfaces: Ensure all mating surfaces are clean and free of old gasket material or debris.
  • Torque Specifications: Adhere to all factory torque specifications for mounting bolts and fluid plugs.
  • Vent Tube: Ensure the vent tube is clear and properly routed.
  • Driveshaft Balance: If new driveshafts are installed or old ones reinstalled, ensure they are in good balance to prevent vibrations.

Following these guidelines will help ensure your remanufactured NP231 delivers trouble-free operation.

Frequently Asked Questions (FAQ)

What does “remanufactured” mean for an NP231 transfer case?

A remanufactured NP231 transfer case means the unit has been completely disassembled, cleaned, inspected, and rebuilt with new or reconditioned components to meet or exceed original factory specifications. This includes replacing all wear items like bearings, seals, and often clutches, and inspecting all hard parts for wear, replacing any that are out of spec. It’s a much more extensive process than a simple repair or rebuild.

How can I identify which NP231 transfer case I need?

To identify the correct NP231 for your vehicle, you’ll need to know your vehicle’s year, make, model, engine size, and original transmission type. Crucially, look for a tag on your existing transfer case; this tag often contains important numbers that specify the exact model, input shaft spline count, and rear output type. Knowing these details will help ensure a perfect match. Contact our experts if you need assistance!
