So im positive that the rear diff fluid in my 1985 has never been replaced. At this point I am looking either to do a flush and refill of new fluid, or just replace the dang thing.

My main question is what is the better route, will replacing the fluid mess with the diff? At this point should I just get a new one? I guess a third option would be getting the old one re-geared?

Any input appreciated.
