Transfer Case

When to Check and Change Lubricant

The transfer case is filled with oil during manufacture, which then does not require changing. It is not necessary to regularly check the transfer case fluid unless there is a leak suspected or an unusual noise is heard. A fluid loss could indicate a problem. It is recommended to have the transfer case serviced at your dealer.
