The truck was a gift from family in 1997. In the Winter, it is used for commuting at a ski resort and snowboard adventures throughout Colorado. In the Summer, it is used to tow a boat to Lake Ontario. The rest of the time, the truck is in Tampa, Florida.
Ford replaced the original engine as warranty work at 90,000 miles, trying to resolve timing chain noise which was not really understood at the time. I replaced the second engine at about 425,000 miles, again concerned about timing chain rattle. Also, have replaced transfer case once, and had transmission rebuilt one time.
The truck is a hobby and a challenge. Stay steady, one fix at a time. Really, have been only able to maintain it through information on the Forum! Thanks again Explorer Forum.
