My Buying Guides on Best Honda Fourtrax 300 4X4 Rear Differential Rebuild
When it comes to maintaining my Honda Fourtrax 300 4X4, one of the most critical components I’ve learned to keep an eye on is the rear differential. Over time, wear and tear can lead to issues that affect performance. After going through the process of rebuilding my rear differential, I’ve compiled this buying guide to help you find the best parts and tools for your own rebuild.
Understanding the Rear Differential
Before diving into the buying options, I think it’s essential to understand what the rear differential does.

A malfunctioning differential can lead to poor performance and even damage to other parts of the ATV.

- Unusual Noises: Grinding or whining noises when driving can signal a problem.
- Fluid Leaks: If I noticed differential fluid pooling underneath my ATV, it was a clear indication that something needed attention.
- Poor Handling: A lack of control while turning can indicate differential issues.
Essential Tools and Equipment
Before starting my rebuild, I made sure to gather all necessary tools. Here’s what I found essential:
- Socket Set: A good quality socket set is crucial for removing and tightening bolts.
- Torque Wrench: Ensuring the right torque on bolts is vital for a successful rebuild.
- Seal Pullers: These help remove old seals without damaging the housing.
- Gear Oil: Don’t forget to choose the right gear oil; I prefer a high-quality synthetic oil for better performance.

- Seals and Gaskets: Ensuring a proper seal is crucial. I opted for OEM parts to ensure a perfect fit, but aftermarket options from companies like Tusk also work well.
- Ring and Pinion Gear Set: If you’re replacing these, I recommend looking for sets that match OEM specifications. I had great luck with those made by Moose Racing.
Where to Buy
I typically purchase my parts from a combination of local shops and online retailers. Here are some places I recommend:
