I am slowing going through this beast and looking for things that will burn me later. There is a single drop of oil coming from the front differential on the yoke side. How big of a bear is it to change the ring on this? How do I check fluid levels, for that matter put fluid in? I know on a regular diff, there is a plug/cap that you can take off and as long as you can touch oil, your good. But I cant find such a thing on this. Any suggestions?
