Just got done building a EMaxx from the ground up. Flm chassis, rpm everything, steel cvd's, waterproof everything, savox servos, cc bec, trenchers. I have shimmed the diff's and run the truck to and blow the rear diff then found out i did not shim the pinion and it slammed into the ring gear. So I corrected that problem, diff seemed perfect wasn't hanging up and seem tight. Ran it a second time to do the same thing but I blew a brand new bearing holding the pinion. I am running gon a 4s and my understanding is I shouldn't be having so much of a headache bout it.
I looked into doing some avid bearing's and if the issue still happens then when funds come available I'll break down and buy some hybrid diff's to accommodate those 1/8 diff's. Any advice to what I may be doing wrong would be appreciated it. I got way to much in this truck to be having something in the drive line causing me a hick up.
