my mip ball diff out drives have been binding with the cvd's on one side only, now one outdrive has a notch in it. this notch is also binding the travel of the arm, i dont notic it when i run but wen i test the damper afect on my table it some times locks and wont come up
my parts:
chuby 300 motor
MIP balldiff
MIP cvd's
GPM rear hubs
trinity monster street tires
Mine did the same..........it was the bolt that goes through the drive cups (thrust bolt) i think its called..........you need to file down the end of the bolt by about 1mm.........and that stopped mine.
Hope that helps

all you need to do is remove the spring that comes with the MIP axle. It is not needed if you have a ball dif cause the bolt holds the dif cup in the tranny.
