This video will show you how to replace the front and rear differential oil and transfer case fluid in the 20112019 Jeep Grand Cherokee. The gear oil and transfer case fluid was purchased from Amazon and I will provide links down below. Make sure you use the correct transfer case fluid because Jeep used three different transfer cases and they require different fluid. The Jeep in this video has the MP2010 transfer case which requires Shell atf 3353. The NV245 requires mopar NV247/245 transfer case lube. The others will take ATF +4 fluid.
