You might have the remote reservoir PS pump which is different than the older pumps in this thread. Since the 5.4 is still in production replacement pumps are at any auto parts store, or the $dealership$.

I just finished the cardone pump swap into my 90 bronco. Despite all the advice saying I needed the 78-79 pressure hose, I am using a stock replacement hose for the 90 bko. I tore up the stock hose removing it from the stock pump, didn't have a flair wrench the right size. That was a $45 mistake!

Cardone replacement pump.


New hose. Remember this replaces the STOCK hose on my 90 bko, unlike what the parts guys are likely to tell you.


This shows the 90 deg elbow that allows using the stock late PS pressure hose. If your Cardone pump does not have this you will need the 78-79 hose.


All done!

 

has anyone tried this to fix a moaner?

I'm like a lot of the posters here - mine (89 4.9 I6) whines like crazy in parking lots but it still works.

I will replace the fluid soon but wont replace the unit until it's broken.

My old '96 Ranger did this too - I changed PS fluid and it was fine.

Could it be that simple? The fluid in my '89 is probably only 20 years old!

I've had it for 2 months and it's definitely a work in progress daily driver.

 

ATF (automatic transmission fluid) will cure that annoying whine that Ford P/S systems are so well known for. You will need to drain the system and fill with ATF, run for 10 minutes, then drain and fill again with ATF.

TIP: After the last fill with ATF, jack up the front end and manually move the wheels from lock to lock with the engine off, then refill the reservoir with ATF and start the engine WITH THE FRONT WHEELS STILL OFF THE GROUND! Turn the wheel from lock to lock a few times and recheck the fluid.

Top off the P/S with ATF, lower the truck to the ground and you are done...nice and quiet!

Check the level again after a few days of driving.

I think this whining is caused because the fluid gets contaminated or somebody put PS Fluid in them. ATF is what Ford wants you to use.

I have not found changing the fluid does anything for the whine.
Just my personal experience.

If you'll follow the steps listed you'll see that we aren't changing the fluid, we are flushing the system and then purging air from the system.

Every Ford I ever owned required ATF in the PS pump.

I was at a NAPA one time and heard a young man (I was a young man as well) ask a salesperson what to use in his Ford Truck because he didn't want to buy the little bottles of PS fluid. Salesman told him to get a large bottle of brake fluid. I tried to correct him but I guess the guy who owned the truck thought the parts counter guy more then another customer.
Can you imagine how well that worked once the brake fluid started sucking up water?

 

Well I finally got around to doing this. The pump has been sitting on a shelf in my garage (make that two garages) for more than two years and I just never found the time to do this. But the pump in my Bronco was starting to squeal really bad and I figured after 20 years and 153k miles I had probably gotten my money's worth out of it.

I also swapped in a redhead steering gearbox so it should really clean up the sloppy steering I've been dealing with for so long.

The swap was really straightforward. It works just like everyone says. I was able to use a stock replacement pressure hose and of course I also replaced the return hose with 3/8" power steering line. Because this truck has a cooler that was full of old, black, nasty fluid, I used the air compressor to blow out the lines.

You will need a pitman arm puller, and a power steering pulley puller. I rented both from the local Napa, which is also where I got the pressure line and the return line.

I just took it for a test drive and I'm pretty excited. No more whine (mine wasn't real loud anyway) and no more squealing. The only thing that worries me slightly is that the pulley isn't quite as close to the bracket as it used to be. It's maybe 1/8" further away from the bracket. I'm hoping this doesn't mean it will start chewing up belts. I'm going to keep a spare belt and a 5/8" wrench in the truck just in case.

 

OK so will this work on my 300? just curious.. sorry for my ignorance. Thanks

 

yes but u need the bracket of a e-series van with the saginaw and the 300 I6 engine

 

ok thanks..

 

lol but i use that power steering repair stop leak and repair stuff... cant remember the name of it.... but it looks like engine oil and smells like *** lol makes it quiet tho and i have a real good coating of the stuff all other the drivers side of the engine compartment coz the low pressure line leaks and i havent had the time to get a piece of hose and some worm clamps to fix it

 

No bracket required if you order the pump discussed in the first post in the thread.

If you use a saginaw pump off a van, then yes you need the bracket too.

 

oh i c.... i mis understood it lol

 

Just did the conversion today on a 1991 F-150 4X4- actually in in the middle of a major doing a 5.0HO install and new trans. Ordered the part# 20-6244 for $49.95 and the stock pressure line ended up being the correct size. Pretty easy install and rented the puller from the same advanced. That puller is worth it's weight in gold and I'm tempted to just keep it for any future work.
Once I get this all back together I'll let you know the results. I am really looking forward to a stronger system since I did the double idler Bullet proof steering it has whined in protest and severly needed a stronger pump. Thanks for the thread guys...............

 

From the sounds of it, '92 & up is when the 78/79 pressure hose is required.

I know my 93 needed the 78/79 pressure hose.

Maybe it's a metric -v- SAE thing?

Also, after having the 20-6244 pump in operation for more than 18 months, it has developed hard steering at idle, until warmed up, when the outside temp is below 40 deg.
Just a minor inconvienience.
Just have to raise revs on engine if doing slow speed turns (ie: parking lot maneuvers) .
Thinking of adding Lucas steering additive to see if it corrects the issue.
