Is the fluid type really that important? I mean, can’t any differential fluid do?

Yes, it can affect performance and durability! Stick to what Toyota recommends for the best results.

Also, having some rags on hand can save you from a lot of cleanup afterward. It can get messy, especially when draining the old fluid!

Great tip! Or you could just embrace the mess and call it an art project. Haha!

It’s a simple process once you get the hang of it, but it really helps to have a buddy assist. Two sets of hands are better than one!

Totally! And having someone to laugh with makes the job way more fun!

Changing the differential fluid is crucial for maintaining your 4Runner’s performance. A common mistake is not fully draining the old fluid before adding new. Make sure to give it enough time to drain completely!

Absolutely! And don’t forget to check your gasket for signs of wear. It can cause leaks if not replaced.

One tip is to use a pump for filling the differential fluid. It’s easy to make a mess pouring it directly. Has anyone here experienced issues with noise after changing their fluid?

I struggled a bit with that too, hillderek. A grinding noise started after my first fluid change. Turns out I forgot to tighten the drain plug properly! Always double-check your work.

Don’t overlook the importance of the correct fluid type! Using the wrong viscosity can lead to performance issues. Always refer to your owner’s manual.

Great point! I once used the wrong fluid and it led to some weird shifting. Lesson learned!

Also, if you encounter a leak after service, check where the fill and drain plugs are located. They can sometimes be the culprits if not sealed correctly during the process.

I find it helpful to lay out all my tools before starting. It gives you a clear view of what you have and helps avoid those embarrassing mid-job runs to the store.

Is there a specific brand of differential fluid that people recommend? Would love to know what works best in 4Runners.

I stick to the brands listed in the manual. They usually have the best compatibility with your vehicle. Can’t go wrong with quality!

Another thing to consider is the temperature of the fluid. Cold fluid is thicker and harder to change, so a warmer environment makes it easier. Keep that in mind during the process!

That’s a great tip, especially during winter months! And hey, who doesn’t like to work in comfort?
