Hello everyone, I have a question that I am sure someone will be able to guide me on what might be the issue. I have an 07 Jeep Grand Cherokee that is a good runner (knock on wood) but recently noticed what looks like oil, but could be differential fluid maybe. I have done alot of repairs on this jeep but never worked on that section of it. The leak appears to have been very consistent for some time now which leads me to think it isn't motor oil but something else. I took a few pics of the location of the leak underneath the jeep and it appears to be where the driveshaft connects to the "rear differential " but hoping it might be something a little easier to work on. Any input or guidance would be DEEPLY appreciated!!!!
