You'll see 2 plugs on the back of your diff. The bottom's the drain and the upper is the fill.
1. drain out your old diff fluid2. squirt in new oil with the drain open, this will flush your system.3. plug up the bottom hole4. take your gear oil (75-90) and fill up the diff through the upper hole.5. keep filling until you see oil come out the filler hole.6. plug up your filler hole and torque to spec7. clean up the gear oil off the diff
