HOLDWELL Gasket & Seal Kit TSK-246

Buying Guide: NP246 Transfer Case Rebuild Kit Essentials
What to look for when selecting a rebuild kit for NP246: compatibility with your year and model, whether the kit includes bearings, seals, gaskets, and a pump or chain, and the level of coverage for wear components. For DIYers, a complete kit with bearings, chain, pump, and filter simplifies installation. For professionals, consider kits with factory-accurate seals and gaskets that minimize leaks after service. Engineered for off-road use or daily driving, check if the kit supports your typical driving conditions and maintenance cycle.
Is a complete kit always better?
Not always. A complete kit is convenient for a full rebuild, but if your NP246 is only leaking at gaskets, a gasket-and-seal kit may suffice. Assess current wear by inspecting seals, pumps, and bearings before purchasing.
How do you choose between different NP246 variants?
NP246 variants may differ in seals, gasket shapes, and bearing sizes. Confirm the exact model number and year range of your transfer case to ensure compatibility with the chosen kit. When in doubt, consult a professional or reference your vehicle’s service manual.
What installation considerations matter most?
Proper torque specs, alignment of the input/output shafts, and correct seal seating prevent leaks and failure. Use appropriate lubricants and cleaning procedures to ensure fresh components seat correctly.
What if the kit doesn’t include a particular part you need?
Some kits omit certain components due to model variation. Have a plan to source missing items individually, and verify compatibility with your specific NP246 variant before finalizing the rebuild.
Are aftermarket kits reliable for off-road use?
Quality is variable. Choose kits from reputable brands with clear component listings and return policies. For off-road use, prioritize kits that include robust bearings, seals, and pumps designed to handle higher loads and dirt exposure.

- Does this kit fit my exact NP246 model and year?
