Why the NP246 Transfer Case Rebuild Kit is Necessary
From my experience, the NP246 transfer case is a crucial component in my 4WD system, and over time, it undergoes significant wear and tear. I found that using a rebuild kit is necessary because it addresses common issues like leaks, gear wear, and bearing failure that can cause rough shifting or even complete transfer case failure. Without rebuilding, these problems only worsen, leading to costly repairs or replacement.
When I rebuilt my NP246 with a quality kit, it restored smooth operation and extended the life of my transfer case. The kit includes all the essential seals, bearings, and gaskets, which means I can fix everything at once instead of chasing individual parts.

My Buying Guides on Np246 Transfer Case Rebuild Kit
When I first decided to rebuild my NP246 transfer case, I quickly realized how important it was to choose the right rebuild kit. The NP246 is a complex component, and having a reliable kit can save you time, money, and a lot of frustration. Here’s what I learned during my search and what I consider essential when buying an NP246 transfer case rebuild kit.
Understanding the NP246 Transfer Case
Before diving into kits, I made sure I understood what the NP246 transfer case does. It’s a part of the drivetrain that distributes power between the front and rear axles, commonly found in many GM 4WD vehicles. Knowing this helped me appreciate the importance of quality parts that can handle the torque and stress.
What’s Included in a Typical Rebuild Kit?
Most NP246 rebuild kits include bearings, seals, gaskets, and sometimes the chain and sprockets. When I reviewed kits, I looked for ones that provided all the necessary components for a complete rebuild to avoid multiple trips to the store or ordering parts separately. Some kits also include specialized tools or instructions, which was a big help for me since I was doing this for the first time.
Quality of Components
I quickly learned that not all rebuild kits are created equal. I prioritized kits with OEM or OEM-quality parts. Cheap bearings or seals might save money upfront but can lead to leaks or premature wear. I read customer reviews and manufacturer details to confirm the quality before purchasing.
Compatibility and Fitment
The NP246 transfer case has different versions and may vary slightly depending on the vehicle model and year. I made sure to check the kit’s compatibility with my specific vehicle. Some sellers provide detailed fitment guides or part numbers, which I found very helpful to avoid ordering the wrong kit.
Tools and Instructions
Rebuilding a transfer case is not a quick job. I appreciated kits that came with detailed instructions or access to online tutorials. Also, some kits include specialized tools or recommend certain tools needed for the job. Having these upfront saved me a lot of guesswork.
Price vs. Value
While I wanted to save money, I found that going for the cheapest kit wasn’t always the best choice. Investing in a reputable kit with quality parts gave me peace of mind and fewer headaches down the road. I compared prices but balanced that with what the kit offered.
Warranty and Support
I checked if the kit came with any warranty or customer support options. Knowing I could reach out if something was wrong or if I had questions was a comforting factor during the rebuild process.
Final Tips from My Experience
- Double-check your vehicle’s exact model and year before ordering.
- Consider buying from a reputable supplier or manufacturer.
- If you’re new to rebuilding, look for kits with clear instructions or online support.
- Don’t skimp on quality; it’s worth the investment.
- Have patience—the rebuild process takes time but is rewarding when done right.
By keeping these points in mind, I successfully rebuilt my NP246 transfer case and got my 4WD system back in excellent working condition. I hope my experience helps you find the right rebuild kit for your project!
