    I need to do the gear oil and gasket on my 96 C2500 8 lug. How do I tell the difference between the semi-float and full float so I know what gasket to get?

    Here's some pics of my RPO codes and rear dif.

    An example of a full floater will look like this:

    The semi floater doesn't have part of the axle shaft sticking out in the middle of the wheel.

    You have a 14 bolt semi float. 9.5” ring gear I believe.

    As stated above you have a semi floater. The full floater diff cover has a "v" shape at the bottom

    They are two completely different axles. It's not like it's the same axle but one has an option, like in the case of a locker.

    I probably should have clarified: I didn't know the diff covers were different.

    I wouldn't **** with a gasket, just use silicone. Either way you'll be scraping next time you yank that cover. I've used silicone only for years with no issues.

    x2, I used silicone (the one-minute gasket kind) for my 98's rear diff and works just fine.
