How Often Should I Change My Transfer Case Fluid?

Check your owner's manual for specific fluid change recommendations. The transfer case fluid should be changed periodically, normally every 30,000 miles, especially in vehicles that tow or use four-wheel-drive often. If the transfer case fluid becomes contaminated or runs low, it can lead to the transfer case burning up. It is much less expensive to maintain your transfer case than to replace it.

  What is a Transfer Case (Transfer Cases Defined)?  

A transfer case in a four-wheel or all-wheel-drive vehicle is part of the drive train. The transfer case transfers power from the transmission to the front and rear axles by means of drive shafts. The transfer case synchronizes the difference between the rotation of the front and rear wheels.

The transfer case receives power from the transmission which sends power to both the front and rear axles. It can be either chain or gear driven. Off road vehicles that are four-wheel-drive (4WD) allow the driver to control the transfer case usage. The driver can put the transfer case into either two-wheel-drive or four-wheel-drive mode. Control of the transfer case may be operated with a shifter or an electronic switch. All-wheel-drive (AWD) vehicles have transfer cases that are not selectable and are engaged at all times in an all-wheel-drive mode.

In AWD transfer cases, there is a difference between the rotation of the front and rear wheels since the front and rear tires never turn at the same speed. Different rates of tire rotation are generally due to different tire diameters, tire wear and tire pressure. The difference in rotation is made up by the transfer case. A transfer case that is not designed for an AWD on-road vehicle will experience binding if driven on dry pavement and most likely will get damaged.
