What to look for / service around 75k miles

[4.8isX5]

So my X is gonna hit 75k this week...

Im wondering what you guys here have run into or recommend to check and look for.

So far i have:

Check belts, if they look bad replace.

Gonna do trans fluid / filter sometime this winter, what fluids do you guys recommend that is cheaper but still meets specs? I have read around some and people give different solutions.

I do suspension components way too much on my other cars, family, and friends, X doesnt really exibit any symptoms of balljoints/control arms/bushing etc so far, when it does ill be swapping those.

Transfer case oil, what type is recommended, and im assuming no filter for it? Just drain and refill fluid, how much do i need.

Front+Rear diffs i did with mobil1 full syn like 1-2 weeks after i bought it back at 63k.

Going to get alignment when i get new tires for rear, current ones are shot, i dont NEED to use my X so i just drive it when its dry out, in the rain rear fishtails when driving at speed on hwy lol.

Power Steering fluid, is it just straight ATF? Does it need to be any special type? Or can i just use this? Valvoline.com > Products > MaxLife > Automatic Transmission Fluid MaxLife > MaxLife® DEX/MERC ATF

^ Posting that one cause i run it in the trans of nissan pathfinder in my family and runs nice. Unless it doesnt meet "specs" or something.

Oh and spark plugs i did like 2-3k ago-ish, so those are done as well..


If i could get some replies for my questions that be great, and the final question is basically what am i overlooking, or did i get it all?

Thanks.


Edit:

Just remembered, coolant flush, what type you guys recommend, & how much do i need of it. Should i do it now or wait?
