When it's all dry, you can set the diff a little tighter than where you would want it at first and run it a bit until the balls are well seated in the ring grooves, and then you tune the diff to the track... If you never use this method to loctite the diff bolt, you will always have issues... The only thing that will break the diff after gooping it like that is if you have a super powerful motor (2.5t boosted) that will pop the diff bolt's head, but no diffing out.....
