Major Leakage...???

[Takecover]

That leak is the front differential vent line. My 04 had the EXACT residue there on the drivers side. If you pull that line off and replace it with the next larger size of tubing, and fill the diff back up, your problem will be solved. In 05 the line size was increased to eliminate that leak. If I am not mistaken, there is a TSB on the exact problem. The only other problem I have had with my 04 was water leaking in both front doors from the wiring "boots". Those are the only 2 problems in 50k miles. Enjoy your new purchase!!
