'98 Explorer Limited
Hey guys, so I've really been using this forum a lot lately with bringing my '98 X up to speed after the previous owner didn't exactly take care of it. This site has a ton of great info, but I found it kind of difficult to find a full inclusive list of what types of things I should do to on the truck right away and at what intervals I should repeat such tasks.

I've slowly compiled my list of preventative maintenance tasks and intervals based off of a lot of searching on here to come up with at least a rough guideline for what and when to do stuff, so I figured I'd share it with everyone to help contribute to the forum since I'm sure many others search on here after purchasing a used Explorer.

Some of the intervals may seem a little low as responses on this forum varied quite a bit so I went with the lower numbers to err on the side of too often, but feel free to share if anything is way off or if I missed any important things to check/do. Hope this helps at least someone out there!

If I was that **** about my car it would last me 1 million miles!!!
 












Change your transfer case fluid interval to 15K, tire rotation to 4K, oil & filter to 4-5K, transmission to 30K, do battery water at 6K, grease ball joints at 3K, slip yoke at 7K, wiper blades at 10K.
 






Change your transfer case fluid interval to 15K,

So most we're pretty close, and there will be variances, I get that, but really the transfer case every 15k? Wow, I was way off on that. I'll add the ball joints and slip yoke (I don't eve know what that is yet) :) thanks!
