Make sure when doing this your inserts are fully seated otherwise your diff will not be smooth or it may even lock. Which was my first mistake using CA glue. On my first diff i had to buy a whole new housing but for the other 2 i re used everything.. I sealed every diff even although the center diff was the only one i noticed leaking. I would recommend this step if you are switching out your grease for fluid.
