If you haven't had them replaced then go do so. Tell them to replace them.... that is what the recall states to do. Ive had it done twice also, when I had my 97 they just inspected and resealed. They told me they were fine, no movement and the car had 30,000 miles on it. When I bought my 99 with 19,000 miles on it I immediately took it to have it done and Satan told me my ball joints had quite a bit of play in them. So it doesn't take long once they start to go.

If you are in doubt then call Satan and ask them to check if it has been done. They will need your VIN number, and should be able to tell you if they were replaced or just resealed.
