Is transfer case fluid the same as rear differential fluid?
The transfer case acts like a differential, but channels power to the two differentials on different axles rather than to two wheels on the same axle. As in a gearbox, a differential and transfer case require fluid to lubricate the gears, shafts and bearings where metal slides over metal.
When to change the fluid in the transfer case?
In our opinion, even for normal driving conditions, the transfer case fluid should be changed at least every 60,000-70,000 miles or sooner if so recommended in the maintenance schedule. The fluid should also be changed if the transfer case has been submerged in water.
When to change rear differential and transfer case?
At 60,000 miles I decided to try and change out the transfer case and differential oil on a 2011 Rav4. The rear differential oil was horribly dirty, the front was okay. Some of the equipment. You can see how much fluid I was left with: I then removed the fill plug on the passenger side by the muffler.
How often should you change the transfer case oil?
In our opinion, even for normal driving conditions, the transfer case fluid should be changed at least every 60,000-70,000 miles or sooner if so recommended in the maintenance schedule. The fluid should also be changed if the transfer case has been submerged in water. Your mechanic can check the fluid condition first and change it if it’s dirty.
What kind of oil does a transfer case take?
In most vehicles, a transfer case is filled with a small amount of gear oil (usually SAE 75W-85, 80W-90 or 75W-140 grade). The transfer case of the Toyota FJ Cruiser in the photo, for example, takes only 1.5 quarts (1.4 liters) of SAE 75W gear oil. You can find the details in the “Specifications” section of the owner’s manual of your car.

When to change transfer case fluid in 4 wheel drive?
When a vehicle is used for towing or is in four-wheel drive frequently, the transfer case fluid is cycled through the system more often. These actions require more torque, which means more heat to transfer. So, while it may be tempting to wait until 70,000 miles (or more) to change the transfer case fluid,…
How often should I Change Front and rear differential fluid?
How often you should change front and rear differential fluid depends on your vehicle, driving conditions and differential fluid quality. That’s a vague answer, but it’s true. If you drive your truck primarily on the highway in temperate conditions and rarely tow or haul, you likely don’t need to change front or rear differential fluid very often.
How much fluid is in the transfer case?
There is no reason to flush, drain and fill is just fine. You could have a quick lube place do the same thing for about $160-$180. Or as you said do it your self but there is probably no drain on the rear, have to suck it out. The fluid is probably 75w-90 in front and rear, maybe 80w-90, and ATF in the transfer case.
