Mark,

Unfortunately I do not have the owner's manual in front of me. I do remember taking my wife's 99 XLT 5.4 for its 100K tune-up to my mechanic - I trust him better than Ford mechanics. Anyhow, I believe you'll need the usual: oil, oil filter, air filter, check radiator hoses, spark plugs (he mentioned that he's worked on a few Expy's where a plug came loose on those aluminum heads), transfer case and transmission fluids checked/replaced. You may also want to replace your coolant and of course have all your fluids checked while you're at it. Oh, forgot about the belts too.

Good luck and enjoy your Expy.

Dan
