I have an 02 f250 crew cab Short bed v10 auto and I want to be damn sure to put the best brand fluids in for axles, transmission, transfer case, engine and radiator. Any suggestions?

 

Use synthetic fluids such as amsoil, royal purple or the like.

 

Those are all snake oils

 

Ford fl-820S oil filter
Ford 5w30 motor oil

 

This is what I use for my oil changes.

I recently switched to Ford Gold Coolant. When I put on a new rear differential cover I found the cheapest 75w140 with friction modifier which happened to be Royal Purple at the time. Front axle uses 80w90. Transfer case takes Motorcraft XL-12, transmission uses MerconV.

OEM fluids are good enough for me, I look for the right specification and cost point. Cheapest MerconV I found was Supertech at Walmart.

 

If you don't have owner manual for it.

Honestly, whatever you put in the axles will be fine as long as it is thick gear oil. For the engine, 10W-30 synthetic blend is good with the stock filter. For the radiator I'd drain out whatever it has in it and throw in some generic coolant. And add in a power steering fluid filter while you're at it.
