Hello! I haven't been active in a little bit because I've been out enjoying my new TJ! Well, new to me and loving every minute of it. Purchased an '05 X with the Rocky Mountain package which had less than 10K miles. After having it for a month I have taken it off road twice and got it stuck is some really sloppy wet mud. That being said, a gearhead friend of mine said that I should change my fluids since I've filled the gearboxes with water and mud. He explained that transfer cases in general have vent holes that will allow water and mud to get in them and mixes with the gear oil. I've asked my other fellow Jeep owners and lovers and they all tell me that its fine, not to worry about it, this is what the Jeep's made for. So, I'm asking y'all for your opinion/advice. I intend on having the 12K service done soon on the Jeep because its getting close to that mileage; however should I have this looked into before the scheduled maintenance? Thanks for any help and advice!
