Well now im onto trying to quiet my noisy steering pump. I read putting synthetic ATF fluid in it might help. Im also gonna throw in a bit of some left over Lucas too

I picked up some Valvoline Synthetic ATF fluid today but all I could find at the parts store in full synthetic was ATF+4. Says its recommended for Chyrsler, Dodge, Plymouth and Jeep. Doesnt say anything about Ford on it... Can I still use it since Im just putting it in my steering pump anyway and not tranny?

 

I've got royal purple ATF in my steering system. no issues in the last year its been in there.

 

i put ATF III/IV cheap crap that was well over 10 years old in mine, its all i had at the time, still works fine.

 

mercon V is synthetic correct?

 

dont put lucas in it! i did it to mine and there will be hell to pay when it gets cold out. the pump is noisier and it is harder to turn. I flushed my system thoroughly and put valvoline syn-power in it which is synthetic and it quieted alot

 

When should this be changed?

 

AHHHHH!! I just did a few hours ago! SHIIIT I hope doesnt f*ck up now... I only put a little bit in, a few squirts. Some people were saying to do it to fix the whine. Well... IT DIDNT ... I now have Valvoline synthetic ATF+4 in there with a bit of Lucas and it still whines like a baby when I turn the wheel while making slow turns... Guess I have to live with it...

 

I've got 24 quarts of Valvoline Mercon V in my garage, think I'll have enough to do my trans and power steering?

 

no korey...you'll run out. go get another box.




lol.

 

Just disconnect the coil, remove the return line on the pump, the one on the bottom of the reservoir, and crank it while turning the wheel lock to lock (tires off the ground) and empty it. Drive it around forst to get that lucas s*** warm so itll come out

 

Motorcraft, and Castrol Mercon V are synthetic blend, I understand that Valvoline has a full synthetic Mercon V.

 

Are we talking about using only ATF in the power steering system? or in combination with power steering fluid?

 

Only ATF

 

I never thought about that or even ever heard of it. So it quiets down the whine better then power steering fluid?

 

They use ATF, in there steering, because that is what ford has specified.

 

lol, IDK what I was thinking when I posted that

 

ATF+4 has friction modifier in it and I know my '05 Dodge used it in the power steering pump, but I don't know if a Ford pump is so different than a Dodge pump that it would really make a difference or not.

I just tried some of this:



in my sister's Explorer just because she has quite a few miles on her truck and I wanted to try it out.

 

Please!!!!





Stay with the recommended ATFs in your power steering!!!

 

I've been using Lucas in my PS pump. I think I might change it out. My pump is loud as hell.

 

I'm surprised that people are having problems with the Lucas power steering additive (I assume that's what is being used here) because I've used Lucas for years in many vehicles and have never had a problem. The last 2 times I've used the PS additive it worked great - 1 steering rack had "morning sickness" and it smoothed out the notchy turning by the next day ... and I tried some in an old F150 PS pump that was leaking an 8"-10" diameter puddle every day and it stopped the leak after 30 minutes of driving.
