88pathoffroad Posted April 9, 2004 Share Posted April 9, 2004 Yes, it's the square plugs on the diffs. The top plug is the fill plug and the bottom one is the drain plug. Loosen and remove the fill plug FIRST so you can make sure you'll be able to refill the diff(sometimes the fill plugs are tough to get out). The rear diff drain plug will have a magnet on it with some material stuck to it. That's normal. Just clean it off as best you can before putting it back in. I'm not sure on weights for gear oil on your particular vehicle, but I use 75W-90 gear oil in my front and rear diffs and transfer case. Rear diff should take 2 quarts or so, t-case 1.5, and front diff 1.5. Just fill it up to the level of the bottom of the fill plug and put the plug back in.
