Changing the fluid in your Honda CRV's differential is an important maintenance task. Ensuring that the differential has clean fluid helps sustain the CRV's performance as well as prolong the life of its parts. Changing the fluid in the differential--the gear assembly used to turn the rear axle--only takes a few minutes. Before beginning the task, make sure that your CRV is in park with the parking brake on, and that the differential has been given several hours to cool.
