Everything has been great on the Ranger, the only real problem I have had is the tranny took a dump at 163000 miles. In my opinion this isn't too bad.
Seats started showing signs of wear along with the pad inside driver side seat is now crumpled up which makes for a bad day.
After a few performance modifactions the 4.0 is an awesome engine to have. Overall the Ranger is top of the line and I seriously doubt I will ever go with anything else, espically if I can get another 160000 out of it.
What were the performance enhancements you did to the 4.0 liter engine?
