X2 post #9, some are simply torn up enough to close up play but still dead.
Post #8 give up, you are proving more and more you are ill-informed. If truly fixed then the first balance job was incompetent, off the car balancing ALWAYS does a better job but of course the worker has to care. The bent wheel should have easily been caught off the car, easier in fact, but it may not be bent at all. If oscillation kicked in due to other parts balancing on car unloaded then the wheel wasn't bent yet appeared to be and now you have the problem still but masked by the way balanced to again show up in the future. Duh.
Now if you yank a wheel to place another one on (tire rotation) you cannot use another wheel, it was not part of that overall balance job, hell, you can't even pull the same tire off and put it back on now as it must be marked to go back on exactly the same way, or again, out of balance. You spread your balance condition to now include the disc and everything else.
Why you balance OFF the car to have universally even tires that can go anywhere to rotate.
We don't call that smart here.
Fix the driver first, then fixing the car becomes so much easier..........
