Ok, I'm in the middle of pulling apart my center diff to clean it and add 7000 WT silicone oil. Well, I realized, unless I am really blind, there is no way to fill it without a huge mess. The screws that bolt the spur gear onto the main diff housing, go through the inside of it. So, if I add oil to it with the spur gear off.......its going to run out the 6 holes. I checked my manual, which doesnt say squat about overhauling the diffs, and went to the Ofna site......and found nothing as well. [] How the heck to you fill this diff with oil[sm=confused.gif]
