Prevent your rear differential from blowing up and costing you a lot of money by doing this simple DIY. BMW says their differential oil is "lifetime" but that is a lie. Unless by "lifetime" they mean until it blows up, which it will, if you don't change it. You will need:
1. 14mm hex wrench or socket
2. A hand pump designed for oil transfer
3. Fully Synthetic Gear Oil 75W-90
4. A level raised up BMW
