Actually Jack's Fix is a bit overkill, these gears do not rotate often in the EVO X (has ACD), they do rotate a bit in the 2g and 1g transmissions (open diff). In an ACD config the gears in the center diff only rotate when power is applied and only for milliseconds (the delay can be set by the tarmac, vs gravel vs snow mode.. snow is the longest delay) until the ACD clutch plates actually lock up the center diff. It stays in that locked state until the power is removed and the cycle repeats. So most of the time the gears in the diff don't even rotate, they are idle. They do however see power, and forces while even at a idle locked state. The real issue was the loosy goosy sloppy clearances they used on the diff housings to gear pins that cause them to walk around in the housing every time power is applied that is slowly shearing off the "pins" the hold the gear pins over time in the housing.
What the Buschur pins do is get rid of that slop, so I think you are safe Murlo.
