The V10's first tune-up is at 100,000 miles. This is what I would do. Change oil - 5w 20 and oil filter. Replace air filter. Check all fluids, engine coolant, power steering, brake, and transmission. Get yourself a grease gun, one with a flexible hose, get underneath and give each zerk fitting you can find 3 pumps. Most will be in the front end at the moving points. You will also have zerks on the drive shaft at the U joints. You may have to pull up or back to see them.
While you're under there you might as well remove the plug on the back of the differencial. Just stick your finger in there and down a bit. If you come back with oil on your finger, it's full.
At 63k miles, it's time to think about the serpentine belt. Check the inside of the belt where the little ridges are. If you can find any parts of those ridges missing, it's time to replace fairly soon. If you see small cracks across the ridges, that's ok as long as there is not more than 5 in an inch. If so, you should think about changing it or at least inspecting it often. These are just guidlines on the safe side. I have a '99 Expedition with 110k on it and still has the original belt. It's never a bad idea to keep a spare while traveling after about 60k.
