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]

7000 is very thick
assemble everything with the spur off,
use a paper towel or clean rag to block the holes
pour in the oil about 50-70% I go 70%
and work quickly but carefully.

Aint that bad

Well, I figured it out. I sat and looked at it with the holes exposed........and thought "hey, put the screws back in!". So, I put all the screws back and held them in place while I filled it up about 3/4 of the way, and put the cap back on. Seems to be ok and I didnt lose a drop.
