If that works, I would next check to make sure the backing plates are not bent; clamp a wire on the hub flange with a point bent and placed close to the backing plate and and turn the hub to see how the plate looks (I would normally use a dial indicator; but the mag base wouldn't stick in this case).

You can also check the hub flange for run-out by clamping the wire to to the backing plate and spinning the hub.

Could also measure the hub; the face is about 3-1/8" out from the spindle face; probably a little hard to do with the backing plate in place.

Between these checks you should find the problem.
