I have a '99 F150 just turned 100k. Is there a timing belt/chain I need to replace? Or other maintenance due at this point?

I replaced the trans oil, diff oil, transfer case oil, plugs, alternator. Anything else to keep her in good health?

Thanks..............PRomo

What does your manual say? Call the service department and ask if they have a 100,000 mile checklist.

You would have a timing chain, but you don't have to replace at this time. Looks like you have everything covered except replacing the fuel filter. Need to change that if you haven't.
