Took 2023 Ram 1500 Limited 4WD in for oil change and tire rotation. 3.21 gears and open rear diff, I believe. Around 43,000 miles, almost all highway driving. Very little towing and no off-roading. Dealership recommends front & rear differential and transfer case fluid changes. All I can find in owners manual is to check at 60,000 miles. Dealership wants $600 for these services. Should fluids need to be changed at 43,000 miles and is this quoted price in the range of reasonableness. Not a mechanic but this seems like unnecessary upselling to me. Your thoughts?

600$+ for diff and T-case oil change.
