If you live in a state that doesn't require an emission check, as I do, the emission stuff is nothing but a waste of fuel. I had the engine out of the truck to do rear main seal/that other stuff so I cleaned all taht crap out while it was easily accessible.
That is old-school thinking ('60s-'80s- pre EFI) no longer true, and not true on our trucks!!!
one of the first things I did when I got possession of the truck was to change all the fluids and make sure they were all at the proper levels. the pump has fluid, I have no problem believing it was neglected earlier in its life. Also I know for a fact that every other component in the steering system is adjusted to proper spec, with the possible exception of the alignment, where I have a little extra positive camber, but that's irrelevant because there was still play in the steering when the truck was in perfect alignment before I installed the larger springs in front.
Oh. I have over 100,000 miles on mine and the only non-original front end parts are the shock absorbers and the tie rod ends.
I did replace a whining pump on a Tempo once. A cheap junkyard unit fixed 'er all up and it cost very little.
There are no synthetic fluids in mine. It is due for axle and trans lube changes though. But, still, I don't see anyone beating my fe with my truck as stock as it is AND mine only gets used when it's working harder than commuting. I know basjoos gets better with his F150 but it's a newer style with different mechanicals; and of course some of the diesels are doing better.
