I have 120,000 on my 98. I have no idea as to what the P.O. did to it maintenance-wise. I've put about 12k miles on the car in the past year and a half.
I figured that I might as well change the differential/transfer case fluids since I recently discovered the stock radiator hoses were still in the jeep and the tranny fluid was VERY dirty. That was a huge tip off that she didn't do much to it.
Any advice? I haven't ever done this before.
