Ford does in fact specify ATF for the power steering. It's either Type F or Mercon depending on year. The Mazda M5OD takes ATF, but some people use GM Synchromesh fluid, which is like a 5W30 oil. You do not want to use gear lube in it, too thick and heavy.

ATF spec'ed all day for the PS pump. Don't even use the name brand fluid in my rigs.

Ford specifies Type F ATF for the C-11 power steering pump. The ZF pump used in the HD/Motorhome chassis requires Mercon ATF.

Mercon is specified for the M5OD. 70-140 gear lube is too viscous to properly lubricate the needle bearings.

It just sticks mostly. The fluid inside is really clouded and very dark anyway so I was just going to drain the fluid anyway. Plus I think there is way to much in it so that might also be a problem...
We will see later today I guess!

Well drained it as much as I could, got at least 90% out of the pump. Poured the clear power steering fluid in. Cut the noise in half and now have better power while turning the wheel. Belt still squeks a smidge at start up but only for a sec then nothing. So Im not sure what to do...mabey wait?

A squeak at start up really isn't a big deal and these pumps are noise no matter what.
If it's really that big of a deal, do a saginaw swap.

Now you need to get that power steering fluid out of there and put the correct ATF in.

With the ATF it was twice as loud and I had twice as much play in the steering wheel. Now with just clear powersteering fluid in it dosn't make any noise really and I have mabey an inch of play in the steering wheel. I think it is an improvment...If it goes it goes and Ill just get another anyway.
I didn't think a saginaw was possible on the 4.9L...either way it works alot better for me.
New thing though, when its warmed up and above 90 outside it squeks for ever! even after I rev it a bit...any thoughts? My next idea is to just swap the old belt tensioner out...

Do what you please dudeman. Go find a e series van with a 4.9 get the pump bracket and lines, boom saginaw pump.
Oh and pull the belt off and make sure all your pulleys line up, using a square and looking down over the pulleys at a 90* angle

And play in the wheel has no relationship whatsoever to anything that is or is not happening in the pump. It can be worn components in the front suspension or steering linkage or it can be a problem with the steering box itself. And 1" is WAY too much.

Is the noise coming from the pump, the pulleys or the slipping of the belt. Once the belt slips and gets glazed it will continue to slip even if there is no other problem

I would say there is a difference in the steering wheel itself, I used to be able to move from left to right with about 3" of play the front end wouldn't move at all. I may have an inch now, but I drove around town and has seem to have gotten better. Could just be me...lol.
The noise is the belt for sure, the belt has less then 100 miles on it so I know it cant be a glazed belt. I had my fiance start the truck while I watched and couldn't really see which pully it was. They all gripped, and they are all square...So I would say it has to be the belt tensioner?

I will have to look into that!
Will have to call around and see what I can find...But since I will really never get over a 32" tire I dont think I will really need that. lol

You won't need the extra power of the saginaw, but it's quiet.
