I am about to roll 60K miles here shortly and I am curious as to which fluids I need to change out? I know some of the maintenance schedules suggest t-case and differential fluids but I also see that they only suggest it for towing or heavy use miles at 60K. I tow occasionally with the following setups, 1000 lbs with my motorcycle trailer (10-12 times a year), 2300 lbs with the camper trailer (1-3 times per year), and 4500 lbs with the SxS trailer (1-3 per year) but I don't see these trailers, weights or frequency qualifying as heavy use. My true off-road use is mild at best but hopefully that is changing here in 2023. So what does the hive think, should I swap these fluids now at 60K miles or should I wait and if so, when should I do so?
