On both of my CRC axles, the diff ring does not 'snap' into place but has a little freedom of movement in every direction, and this means that in break-in and running the rings move and dont wear a seated ball grove, but more of a wide polished area... meaning it never really breaks in. This is okay for blinky, but without that grove the diff needs to be quite tighter than I like in order to hold under higher power. Other axle makers, like Serpent, have a good tight hold on the rings and produce axles with great hold, just not mine. Would it be prudent to glue the rings directly to the ring seats? Not permanently, just to take the play out of it so i can get good a good ball-ring grove which can take the power.
