OK, bought the 75W90 oil today after reading through Eddie's writeup. Here is my dilemma: bought the Jeep at 28k miles and it's now at 38k miles. It hasn't seen that much off road use in it's life yet. I just called the dealership of the previous owner and they verified the differential has never been serviced. So, it's definitely due for an gear oil change. The problem: I'm going on a 4 day off-roading trip in a few weeks here in Colorado that may have some river crossings; unsure how deep.
Do I change the fluid now because it's past due and hope no water gets in there on the trip, or wait till after the trip and change it then?
