Yesterday we (Chris4x4, and I) got together to help you all change your diff fluid.
Here is what is required;
-24mm socket (1st gen diff may be a different size)
-milk jug or coffe can... EMPTY ofcourse!
-3 qts 75-90 weight gear oil ( I used 80-90 becasue it was readily available)
(for you guy like me w/ the Sport model, you'll need a 4oz. tube of LSD additive).
First step is to remove the higher of the two plugs ("fill/vent plug").
Step two, remove the lower plug ("drain plug"). Be sure your jug/can/tub/pan is handy.
While the old gear oil is draining, take the time to clean off the magnet on the end of the plug.
When the oil has completely drained, replace the lower or "drain plug".
Now you can begin to refill your differential! You should add your LSD additive sometime between your first and second quart of gear oil.
When filling, the oil will begin to run out at some point. Put the plug in the fill hole, and let the gear oil run down into the lenght of the axle shaft. After a few minutes, remove the plug and begin to fill again.
Remember to replace your fill plug! And to torque the fill plug, and drain plug to 36 ft- lbs
