Driveline Service

I recommend a Driveline Service about every 25,000 km or once a year. A Driveline Service,depending on where you service,  basically means the fluids the driveline get changed. While the transmission is also in the driveline, they are a seperate service because of there complex nature.

Differentials and transfer cases both operate without filters. So anything in the oil continues to circulate through the system.

While most have magnets to deal with metal filings, both differentials and transfer cases have vents to the outside air. These vents allow for expansion and contraction of the fluid when it gets hot and cold. This also allows dirt and moisture to enter the system through the vent. The only way to deal with this dirt and moisture is to contain it in the fluid. The only way to get rid of it is to change fluid.

Using the recommended fluid is very important for these components. Some differentials require additives to allow for limited slip components to work. While other transfer cases, can not engage properly with incorrect fluid.

Keeping the inside of these units clean can make a huge difference in its service life. It also helps maintain your warranty.
