If either of these are off far enough, you are not getting a good mesh and could strip the tops of the teeth off. Of course, even if shimmed perfectly, a powerful enough setup will destroy them anyway.
I had my BL Revo (converted 2.5, 9XL, 14 cells) for about a year or so and never had a diff problem.

after a year i lost a diff after a violent crash bent my rpm arm and drive shaft! I rebuilt with the aluminum drive cup. However id like to shim them to make sure they are tighter - what size shims and where to get?
