1) What is the recommended brake fluid change interval? The list at WK2Jeeps.com does not have it (Jeep Grand Cherokee WK2 - Maintenance information and schedules
2) I have Quadra-Drive II. I have 23,000 miles on my WK2 so far. I off-road occasionally, but also do a lot of highway driving, with no towing so far. I do drive with a heavy foot in the city. Should I follow schedule B (18,000 miles, i.e. change it now) or schedule A (36,000 miles) for the differential fluid change intervals? It is obvious that some of the conditions for the "B" schedule have nothing to do with the differentials.
