Is it the outer ring wobbling of the entire damper? From what I can tell, the assembly indexes / datums axially on the OD of the timing sprocket and is held square by its face.

If your sprocket was loose, you could have a problem(EDIT for clarity: ID of pulley or OD of crank).

Another test would be to check the runout with the motor off. If you take the pulley back off again, look for fretting marks to see if its moving.

The outer ring will move in response to engine harmonics, but its not supposed to wobble.
