My drive shaft had to be replaced at 35,000 miles.
This truck has been the most reliable vehicle I have ever owned.
I have owned this Ranger XLT 4X4 for almost 13 years and it has never had a tune up or had any of the plugs and wires changed yet.
Ummmm, you might want to look into getting a tune up for it. It don't cost much, and will add years to the life of your truck. Hopefully you've gotten oil changes done every 3000 miles though.
