Changing your Mustang's rear end gear oil is one of the most overlooked maintenance jobs. Even though it may seem intimidating, the process is quite simple. Follow along as we walk you through how to change your Mustang's gear oil.
Flat Head Screwdriver
Brake Clean (Optional)
Lift your Mustang with either a jack and jackstands or with a lift.
Place a bucket or drain pan under your rear end, and loosen and remove all but the top cover bolts.
Using a flat head screwdriver, pry the cover open and allow the fluid to drain into the drain pan.
Once the oil has slowed to a drip, loosen and remove the top bolt, remove the cover and set aside.
Scrape off any remaining gasket and clean the differential with brake clean. Do the same with the cover as well.
