Is there a recommended mileage to replace the tiiming belt on a 2003 Ford Expedition XLT? Not the Eddie Bauer version

Hi: The ford expedition came with a 4.6L V8 or a 5.4L V8. None were built with a V6. Regardless, both V8's do not have a timing belt, but rather a timing chain. It should last well over 100K. Actually, it will start making noise when it starts to stretch and get loose, but I have only seen that one time.
