This video applies to all Nissan/Infiniti models with a rear diff. Check your Service Manual for gear oil weight and amount needed. In this case my G35 takes just under 2 qts of 75W90. Feel free to ask any questions in the comment section and I will also link the fluid used and the gear oil pump below.
