I did not notice this at first, it wasn't until I could see that the wheel rotation was out of truth (difficulty in setting up the tracking) that I had to investigate and spotted this problem. The profile of the angle on the drum differed to that on the angle of the hub - this has a curve - the drum is square - and once they matched it was fine, it is hard to see at first, only has to be slightly out, if the drum rocks slightly before the screws are fitted, then that is your problem.
Good luck!
If I understand what you are saying- the new front hubs have a sharp corner where the flange meets the body - technically not a good thing, promoting a failure at this point ?
