In this video I explain how I change the fluids in my differentials and transfer case. Overall, this is a very simple maintenance service that can be completed without taking it to a dealership or mechanic. Doing this service yourself can save you hundreds of dollars. Basically, each serviceable part needs to be drained and refilled. If this video was helpful for you, please leave a comment below. Thanks for watching.
