Thanks for the suggestion although that was an issue about a few months ago
Oh and the issue is not that the pivot balls fall off easily but it sits at the end of the drive cups. A sudden twisting or bending on the shaft due to extreme acceleration will cause it to shorten the length causing it to come out. Limiting the shock travel did a lot and I havent found any other issue except my the ESC died.
Again thanks for the input I will consider it next time I rebuild this truck..
