1997 Jeep Cherokee Sport 4.0 auto
Just curious about changing the fluid in the transfer case. How difficult is it? What type of fluid should I use? I realize that age and mileage essentially mean nothing to gear oil, but aside from keeping my vehicles well maintained, I like to tinker with them and changing the fluid in the transfer case sounds like a good tinkering project.
Second up is changing the u-joints on the front end. Again, how difficult? There's a mild vibration in the front end when the speed gets up around 70+ [not that I'm doing 90, but I typically do about 75 on the interstate] and I suspect the u-joints to be at least part of the problem.
