8 3/4” axle leak

Hi All,

I’ve noticed a fluid leak where the 3rd member differential carrier meets the 8 3/4” axle housing.
Wanted to get some info on who had success in stopping the leak and method they used.
Is it better to use a gasket only, or use high temperature silicone only, or use both gasket with high temperature silicone together?

Much appreciate your time and reply,
Thanks
