If you switch the wheels, you can easily find out whether the problem is
the wheel or the grinder. Then you go from there.

I have a two 8" grinding wheels-grinder for sharping my turning tools. The
one wheel is wobbling quite abit and the other one does not. I have removed
the wobbling wheel and there does not appear to be a damage to the shaft or
the serrated bushing holding the wheel onto the shaft. There are two large
metals discs one of the inside of wheel and one on the outside of the wheel
behind the nut that holds the wheel onto the shaft, There doesn't appear
any excessive wear on the center of the grinding wheel attached to the
shaft. This condition just started recently.
When purchased(3 years ago) both wheels ran true Any suggestions?
