Sorry that I didn't read through all of the threads... Is this stuff good for the Gen II diffs, too? I'd like to standardize on one fluid. My Gen II diff whined like crazy, so I swapped in Red Line fluid which sorted it out completely. But, if there's something out there that will fix that problem, I'm going to stock up on it. I might even use it in my Rubicon 392 diffs if it meets those specs. The Rubicon diffs get crazy hot....
