Using this rear differential cover is simple. Just replace your old cover with this new one following the standard procedures for your 1994 - 2023 Ford F - 150. When you're servicing the differential, make sure to replace the copper washer (Part # 114052002) with a new one every time to ensure a good seal. To maintain this cover, regularly check for any signs of damage, like cracks or dents. Also, keep an eye on the differential fluid temperature and level. If the temperature seems unusually high, it might be time to have a closer look at the cover and the differential system.
