This is a big difference. The terms you use in your posts are not what are commonly used, hence our confusion. This is one reason why good and many photos can help shorten the translation from your terms and our experiences.
What I tried to explain in my first post was the difference between the BB/bearings being sloppy/loose and the chainrings being out of true. Both can have similar initial looks but have vastly different solutions.
Now you're talking about rear hubs. I'll try to help more but after a few replies and continued inability to really understand your questions it can be a challenge for us too. Andy.
I was just replying about a separate issue. I think that the chainrings are out of true. Nothing seems loose on the bottom bracket but the way the chainrings line up with the front derailleur still seems to change as they rotate, which causes the chain to move laterally when its on either of them.
The hub on the rear wheel also wobbles but that is a separate issue which I don't actually think is significant enough to be causing the lateral chain movement.
Sorry for the confusion. I can take pics in the morning.
