Is that fact or just conjectur?
Good job this is a rumour network or you might just have opened yourself up to a damned good court case. I'm quite sure the engineers involved might not see the funny side though!
Why would you remove a drive link nut during track and balance? Serious design floor there then!

You would have thought with 4 pitch change links and 2 drive links you would have at least 45 degrees of seperation between the various components.
