I don't have the manual that came with my 99. I'm going to do a fluid change and have 4 quarts of Mobile 1 75w90 and fric mod. Will 4 quarts be enough and how many oz of fric mod do I use, as well. Lastly, how do you tell when it's to the full point. TIA

 

I believe it takes 3 quarts of oil and 4 ounces of friction modifier. You fill it until it just starts to come back out the fill hole.

 

2.6 liters of fluid, plus 4 OZ. of friction modifier.

You are supposed to stop filling the rear end when the fluid is around 1/4" below the fill hole, according to my owners manual...
