Explorer power steering pump pressure and volume modifications

This is how I got more pressure and volume out of my Explorer 5.0l power steering pump. I don't have any numbers to share. Only that it made a big difference in my steering with the RAM assist and 40" tire's.

Thank you for this! I'm going to have to figure out how to do similar on my Jeep WK pump; it's a bit different than these, but you gave me a starting point!

[@jessebarraza6039]

I did this to my F250. Steerings way better when its not moving. The pump is loud now. Lets see how long its lasts. Did ur pump get loud?

[@Low_Key_Offroad]

My pump did not get loud. Is it possible you have air in the system?

[@Fordtruckfan89]

Ive pulled apart several later 4.0 c3 pumps and they dont have the node sticking out, its a smooth shuttle valve. I imagine they have a smaller hole than these too

[@Low_Key_Offroad]

I have found that the node was on 97 and up as a rule. I think the node is there to limit flow in a stock application.

Finally! I hate how stiff my steering is

[@Low_Key_Offroad]

You won't regret it

[@Gloccthejocc]

Would I be able to achieve the same with a reducer on a smaller hose. I’m lookin to put in a power steering cooler. But it’s a 5/16 fitting not the standard 3/8. What’s ur thoughts

[@arontesfay2520]

Can I do this without removing the pump and/or draining the PS fluid?

[@justaboutsound]

Hi can you help me getting my power steering pump modified. I want it to be 25% more lighter.

[@Fordtruckfan89]

Question on a stock application my explorer has a new rack and pinion, reman pump, steering assist is lacking at idle, would just removing the restrictor nipple keep the pressure the pressure the same but help with the lack of flow? Not trying to blow out a new steering rack from excess pressure.

[@Low_Key_Offroad]

I'm not exactly sure. It couldn't hurt it. You may consider putting an underdrive pulley on it to make the pump spin faster at an idle

[@Fordtruckfan89]

Any idea where I can get one?

[@Low_Key_Offroad]

@@Fordtruckfan89 Driven auto is where I got mine.

[@randumadventures]

So a year later is there any down side to this mod or still working good?

[@Low_Key_Offroad]

It all works great. Runs by Ram assist well.

[@CorkscrewTrail]

Two of them I’ve done this to are still going strong. I’m going to build a larger reservoir to lessen the cavitation to the system since I’ve added hydroboost and 35” tires to the load.

[@rcazarez13]

I have a 5.0 from a explorer and a crown vic front clip. The steering is kind of hard you think this may solve my problem?

[@Low_Key_Offroad]

Yes it will.

[@rcazarez13]

@@Low_Key_Offroad Thank you

[@VileMisanthropy]

How did ypu get the shuttle valve out, Mines stuck.

[@Low_Key_Offroad]

You should be able to pop it out fairly easy with a small punch. Not sure why yours is stuck.

[@VileMisanthropy]

@Low_Key_Offroad honestly, I think its the "reman" pumps I'm getting, there rust residue inside. I did get it out through the bottom with a punch, shouldn't these move freely?

[@Low_Key_Offroad]

@@VileMisanthropy yes it should move freely.
