Anyone have a link or info on flushing power steering pump?

[jshalala]

I saw somewhere on here that flushing the power steering could help with a noisy pump. So if you could tell me how to do it or shoot me a like that would be awesome.
One other question. Do our super duty trucks have a hydroboost? system that controls braking and power steering?
Thanks

Yes, our trucks have hydroboost. I used this method:

Ford Super Duty Power Steering Flush | Superdutypsd.com

You will need a helper to pump the brakes and turn the wheel while you add fluid as you go. These trucks move little to no fluid with them just idling and no turning/braking.

Thank you sir! Maybe this will help take care of some of my whining noise

It quieted mine down, and steering is much easier at low speeds. I went with Valvoline MaxLife.

Nice. I'll hit up the parts store. And do you know what the hydro boost system consists of? Is it the way the power steering and master cylinder run? Obviously they are both connected, but can hydoboost go bad while the steering pump and master cylinder are working fine? I guess what I'm saying is what is hydro boost and how does it work. Bam

Is there a specific Valvoline Max Life ATF to use?

If your power steering pump goes bad, you won't have power steering or brakes...

Mercon/Mercon V. I use it in my tranny and power steering since it's readily available.

Speaking of tranny, I bought this truck in Dec of last year. I don't know any of the history as far as the fluid being changed on it. I also don't have any issues as far as shifting goes. There's 148,000 on it now, so should I change it or not. I still hear diff opinions on this subject. Sorry to hijack, btw.

Mine has 149,885 (NOT 150k! ) on it and I've had it since 95K... Every now and then, I'll pull the drain plug on the tranny, and let it drain out the 8 quarts, then re-fill, and go. I've heard bad things about doing a complete flush on old trannys. The complete tranny holds like 18-20 quarts.

I used the Mobile 1 synthetic ATF. Most folks recommend it on the board.
