Ok, Dummy me should have said in the original post that the Jeep was bought new but wasn't driven consistently until the last four years. I used to drive the Mustang GT and only drove the Jeep during the Winter months. Now I drive it all the time. I am not saying anyone is wrong about their guess,,,,,,,,,,, The ones that have posted a guess BEFORE this Update can re-guess if they want to. Sorry,,,, you all knew my dumb butt would mess this up. lol Good luck & have a great night, Mark
