Thank you to Spect2K for the detailed posting with pics. I was about to begin drain and fill of the diffs last weekend, after a regular oil change, but decided against until I could find the fill plug for the front. Glad I waited. And I did get new washers. I am going to use Valvoline synthetic 75w90 BTW.
