One more thought

That lens is between 21 and 25 years old so may have some serious mileage under its wheels. That is likely to include a loss in precision in the AF drive system through wear so I would not be surprised if it is less precise than a new lens. Just a sad fact of life and nothing you can do much about I'm afraid.
