Quieting Down Our Loud Power Steering Pump - Before and After Decibel Testing

just a power steering pump, screaming for it's life...
Our OBS Ford F150 (1995) has one of the loudest power steering pumps I've heard. I was looking around online and found lots of people saying that a modern fluid like Dex/Merc or Dexron VI will quiet them down. The original owners manual recommends Type F fluid FYI. While I agree that those fluids are superior, I wanted to see how much it actually made a difference.
At the same time I wanted to flush all the old fluid out of there and install a power steering line filter. I went with the iFJF brand instead of the Magnefine which - so far, so good! I hope you enjoy our journey of testing power steering fluid with our decibel meter to see if it's actually quieter (and turns smoother too)!
Let me know if you want me to test other fluids and we'll give it a shot!

my 91' f150 screeches every turn of the wheels, its really great when people already stare at an old hunk o' truck and then have the sweet sweet opportunity to hear ford engineering.

I just found out about your channel and the content is just great! I like the jokes in between the science! This channel sure will do great, just give it some time!!

Thanks buddy! I’m glad you found me and that your here! No promises that it’ll always be funny or useful videos though - and the refunds department has notoriously shitty attitudes, so beware…

I thought it was very interesting to learn that Fortune 500 companies also use an ‘06 Tahoe as their mascot. Now I feel a little bit smarter today.

It’s a pretty low key fact, so I understand if you’ve never seen it before. “The more you know”

The lucas worked for me.

I've tried Lucas additive, a new pump, lines, and rack. No air in the system. Still noisy AF.

You sir, deserve a Saginaw pump swap! I’ve had “rebuilt” pumps from the parts stores be louder than the pump I took off haha. Just a noisy design imo

[@thisisyourcaptainspeaking2259]

The Ford power steering pump tends to trap air, causing buzzing.

[@MatthewFinlay]

Gotta bleed these babies - or swap to a Saginaw. Honestly that’s the easiest way to quiet them down haha

[@dougsammons2228]

Two oz's of brake fluid,,,,it works

[@BrandonW]

Can you put the old fluid back in see if the noise returns? That's really the only way to see what the cause was.

[@MatthewFinlay]

Yes! I just gotta get it outta the catch pan….. oh….

Drop the clown act…just say’n
