I inherited 2 of what i guess are the original arrma granite. Had the replace the electronics and motor on both. got them both up and running. One got brushless setup other got a brushed motor. both have held up pretty well except minor stuff. the one running the brushless setup has started acting like it has a limited slip diff. when you spin the tires both turn in the same direction. if you hold one side the other spins with a little resistance. would be good but with all that power its really hard to lay down the power without spinning out coming out of corners. I took the diff apart and found there are washer shims that were deformed. they are part of kit ar310378 what i was wandering is does anyone know the size of those shims? I flattened them with a hammer and put the diff back together worked fine till i took it bashing then it started doing it again. Also I put rear end dope in it i had laying around. is that good or do i need to use the silicone stuff? It does not seem to be leaking out.
