Truck is moaning at me

What is this noise??
I thought my power steering pump was going out on me because of a little difficulty steering and the moaning sound coming from under the hood while steering. Now IDK what it is because it also makes the same noise when I press the brake pedal. The harder I press the pedal, the louder the moan is?!?!

What is it?

These truck use the same hydraulic pump for the power steering as the brake booster so that's almost certainly what you're hearing. It's pretty common for Ford pumps to make some noise when they get some miles on them but it shouldn't be so loud that you can hear it at anything above an idle. Start with checking fluid level and if it's low repairing any leaks.

Fluid is good last time I checked.
Pump going?

Its the power steering pump. I just had mine replaced and it was doing the exact same thing.

Never done one.
How do you replace it?
Any tricks to it?

It's normal trust me. I made a HUGE thread on this. Thats the nature of the beast with these. I'll tell you what works though, Lucas Power Steering additive. It made my pump ULTRA quiet, and it's so smooth and un-rough now. the lucas is like 7-8$, but it was well worth it.

I wouldn't say it is normal. This is the first it's started to sound like this since i've owned the truck.
I will def try the PS additive though before I just go replacing the pump. Thanks man

It's VERY normal for these trucks. Maybe not directly from the factory, but after miles and years, it's normal. Check the fluid when its up to operating temp. I'm willing to bet that additive will work well though. It quieted mine down 98% of what it was.

See how dirty the fluid is. Pulling some out and adding fresh will probably
fix the issue also. I try to pull some out when I service the trans and
add fresh... no problems

Just as a follow up to this....
I finally bought the Lucas additive.
It worked INSTANTLY! As soon as I put it in the noise was completely gone, and the steering works normally again.

Thanks for the tip! This worked great.
