2015 GMC Yukon Denali XL Rear differential gear oil change

[@aroundthehouse2022]

Hi. The vehicle has 120,000 miles and is new to me. With no service history I service all the fluids as part of routine maintenance. Thanks for watching.

[@aroundthehouse2022]

You can buy a pump like this at any auto parts store. It’s called a gear oil and fluid pump.
