Changing the differential fluid in your Toyota 4Runner is a crucial part of maintenance that can help ensure smooth operation and prolong the life of your vehicle. In this guide, I’ll walk you through the steps to perform this change yourself, including the tools you’ll need, recommended intervals, and the correct fluid specifications.
When to Change Your Differential Fluid
The general recommendation for changing differential fluid is every 30,000 to 50,000 miles, but it’s always best to check your owner’s manual for the specific recommendations for your model year. If you frequently go off-roading or drive in harsh conditions, consider changing it more often.
Tools and Materials Needed
Tools:
Socket set
Torque wrench
Fluid pump or siphon
Pliers
Drain pan
Ratchet
Materials:
New differential fluid (check specifications for your model, typically 75W-90 gear oil)
New gasket or sealant for the differential cover
Step-by-Step Guide
Prepare Your Vehicle
Park your 4Runner on a flat surface and engage the parking brake.
Place jack stands under the vehicle to secure it if necessary.
Drain the Old Fluid
Locate the differential cover underneath your 4Runner.
Use your socket set to remove the bolts holding the cover in place. Once removed, gently pull the cover off and allow the old fluid to drain into the pan.
Inspect and Clean
Check the condition of the old fluid. If it’s metal-laden or has a burnt smell, it may indicate further issues.
Clean the differential cover and the sealing surface on the housing.
Replace the Gasket
If you’re using a new gasket, install it onto the cover. If using sealant, apply it evenly around the edge before replacing the cover.
Add New Fluid
Using a fluid pump, add the new differential fluid through the fill hole until it starts to seep out. This indicates that the differential is full.
Reassemble
Reattach the differential cover and tighten the bolts to the manufacturer’s specifications using your torque wrench.
Final Check
Start your vehicle and check for leaks around the differential cover.
Make sure to dispose of the old fluid properly at a recycling center.

Congratulations! You’ve successfully changed the differential fluid in your Toyota 4Runner. Regular maintenance like this can help you avoid costly repairs down the line. Don’t hesitate to ask questions if you encounter any issues or need additional tips!
Changing the differential fluid in a 4Runner is essential to keep it running smoothly. First off, make sure you have a good jack and jack stands for safety. A socket set will also come in handy for those drain and fill plugs.
Great tips! For the differential fluid itself, I recommend using a synthetic option for better performance and longevity. Just make sure to check your owner’s manual for the correct specifications!
I usually go for Mobil 1 or Valvoline. They’ve worked really well for me, but do your own research based on your driving conditions. You might want to experiment a bit!
Changing the differential fluid is crucial for keeping your 4Runner running smoothly! Start by gathering all necessary tools: a socket set, a fluid pump, and, of course, the right differential fluid.
To access the differential, you’ll typically need to lift your 4Runner and securely support it on jack stands. Make sure the vehicle is level to avoid fluid spills.
Once you have access, drain the old fluid completely before refilling with the new fluid. It’s important to clean the fill and drain bolts to prevent contamination.
