    You can still get fluid back in.

    Just get a couple ziplock bags, in the quart size. Fill each bag with lube, then stuff them into the diff housing. Drive the truck. After a few feet, the lube is out of the bags... after a mile or so, the ziplock bags are now "posi additive". Seriously though, the mutilated bags won't hurt a thing.

    Numbers on back differential

    Can any body tell me what these numbers mean. They are from my 1987 Chevy 1/2 ton 4x4, 350, 5.7 tbi. The numbers are off my rear differential:
    GM1, H126, 14055251. These are the only numbers found on it! Thanks for the help.

    The Squarebody Reference Library has some info there that might help you, but those #'s don't mean alot. The 14055251 is probably just a part #. I think the H126 is a date code, but that will not tell you anything as far as the carrier of gear ratio. This link should help locate the code you need, then look up the code and unless someone got in it making changes which is usually not the case, then you should know.

    Thats awesome. Someone should just make pre-filled bags packaged in small boxes. Keep all those plastic jugs out of the trash.....

    What about 5th wheel grease pouches? Those are pre-filled pouches used to grease fifth wheels. They burst once a load is put on them.
