I had this same issue with a rear diff & transfer case.
It was a (jeep) Dana 44 rear end 4.11 gears & a (jeep)231 transfer attached to a lexus V8 converted vehicle.
So loads more strain & heat on the parts than standard.
I ended up using Wurth gasketmaker & had no issues for over 2yrs before I sold it.
I have no idea if the gasket provides necessary extra clearance, although I doubt this.
My only advice if going this route is to the prep/clean the surfaces very very well & dont be in a hurry to put it back together or run it until it has cured properly.
