[QUOTE="Gilaguy23, post: 436113, member: 19498"] You need to follow the breather vent hose to the end where there should, or was, a little plastic spring loaded diff breather. They get crapped up and dont allow breathing of the diff as it heats and cools. From what I see id say its plugged and causing the pressure in the diff which is making oil weep out at the axle tube where the diff vent starts as well as the diff cover plug. I'll add the rubber diff cover plugs get old and hard and don't seal great to start with. You can buy new ones also from Quadratec I believe. Just be careful if you try to pry it out as some of it might end up breaking off and ending up in the diff. Then it's a perfect time to remove the cover, clean out the 30 year oil crud, reseal and refill with new 80/90 gear oil. [/QUOTE]
