This makes the rings dead flat and smooth. If you do this alone your diffs will last months longer.
CA'ing the rings lets you set the diff even looser without ring slip. I have run diffs as loose as 3/8 of a turn that required great force to make the diff slip.
I really don't glue my rings anymore as I run Mod mostly and you don't want your diff too loose with a 7 turn. I usually run 1/4 turn lose.
Note that the EC comes stock with the U1954 thrust bearing. This means the thrust bearing is pretty much good for the life of the car. If you ever get a gritty diff. Flip the rings first and if it is still gritty replace the diff balls.
