About the transfer case:

Are you looking to maintain the longevity and performance of your 4-wheel drive vehicle? If so, transfer case fluid replacement should be at the top of your maintenance list. This often overlooked service is vital for ensuring the health and efficiency of your transfer case and drivetrain.

The transfer case is a vital drivetrain component in four-wheel drive (4WD) and all-wheel drive (AWD) vehicles. Its purpose is to direct drive power from the transmission to all four wheels via the front and rear axles. The transfer case controls which wheels receive power depending on the mode your car is in. For example, only the front wheels will receive power if the car is set to two-wheel drive mode.

Transfer cases require a lubricant to function correctly. This keeps the gears moving smoothly and prevents friction between the various moving parts. This lubricant is usually referred to as transfer case fluid.

When to change the transfer case fluid?

Most mechanics recommend that you replace the transfer case fluid once every 50,000 km. However, the average life of the transfer case fluid depends on how your vehicle is used. If you regularly tow large loads or put other forms of stress on your transfer case, the fluid should be inspected regularly. This ensures that there are no leaks and that the fluid is keeping its lubricating properties.

Changing the transfer case fluid is important for several reasons:

  • Lubrication: Transfer case fluid serves as a lubricant for the gears and bearings inside the transfer case. Replacing the fluid regularly helps to ensure that these components are properly lubricated and protected from wear and damage.
  • Contaminants: Over time, transfer case fluid can become contaminated with metal particles and other debris, which can cause damage to the gears and other components. Changing the fluid helps to remove these contaminants and keep the transfer case running smoothly.


Symptoms of transfer case fluid in need of replacement:

  • Difficulty changing gears – Low or dirty transfer case fluid can affect your transmission’s ability to shift gears. It can also result in your car unexpectedly falling out of four-wheel drive.
  • Loud noises while driving – As the transfer case fluid loses its lubricating properties, friction will occur inside. This will create loud grinding noises which may become louder when four-wheel drive is engaged.
  • Leaks – If you notice fluid leaking from the transfer case, it could be a sign of a damaged seal or gasket, which could allow fluid to escape. In some cases, fluid leaks can also indicate that the fluid has become contaminated and is no longer effective.
  • Decreased Performance – If you notice a decrease in the performance of your 4-wheel drive system, it could be a result of low fluid levels or contaminated fluid. In either case, it’s important to have the transfer case fluid checked and replaced if necessary.
