Yes sir, my original open diff, now packed with ARB, is sealed with grey permetex and standard torque on the standard hardware for nearly 4 years now and nary a leak after much bashing and grinding.That should be on the occasional torque check list. If the gasket is ditched and the diff is installed with Permatex Gray, the nuts almost never come loose and leaks are greatly reduced.
Edit: I do regular torque checks on all critical hardware.
