Whining Power Steering Pump

[racerat94]

I know I'm not alone on this one.

My power steering pump whines so much it makes the truck sound like a piece of sh*t ! It works fine so I'm afraid of replacing it with a new one that will sound the same way.

The pumps Ford uses enherently whine.

Anyone know of any liquid fixes or whether or not aftermarkets whine ?

thanx

When does this happen?

 

[racerat94]

Constant at low RPS's.

I got a thin turkey baster and removed as much fluid as poss and added 1.5 bottles of Lucas Pwr Steering Fluid and Stop Leak. It is thick and red and has notcieably quieted my noisy pump and whining. No leaks either. Costs about $8 a bottle. Try this before replacing your pump.

I cured a similar problem by switching to synthetic fluid.

Good luck.....

Did you have a shop do the fluid change or did you do it yourself? If you did it yourself, how did you do it?

TIA,

I had a friend with a '74 Dodge Dart put gear lube in his PS system. Quieted it down allright, wore the snot out of the pump though.

Mine growls all the time too. they are extremely sensitive to air being in the system and are a pain to bleed. I've pumped air into mine on several occasions trying to find the source of a front end clunk.

Might try that Lucas stuff first and see.

If I remember correctly from my experiences with my old '91

1. Any air in the system at all, I mean ANY will cause a
whine, make sure you have not a single little leak
because that means your allowing air into your
system.
2. Do a search, infact maybe even on this site about the
high pressure line to the pump having a little govener
(ohh i'm forgetting in my old age) more like a ring that
can be drilled out to allow for more flow and less
strain, they used to do it on the bronco's.
3. If you were considering a new pump, get a pump
from a newer explorer that has the remote reservoir,
they were suppose to be better than the older style,
ask at the parts desk at ford they helped me get
mine.

Good Luck

Adam, that is ONE NICE LOOKING X! I had a '92 just like that (before pic). It's a sad story what happened to it, but I replaced it with a '94 the exact same color.

I tried the solution posted by rossneag and it helped out alot. It still whines a bit but now it is alot quieter.

Thanx rossneag for the help.

i read somewhere that a magazine tech article where they put some type of synthetic Mystery X oil in it and it worked better than the ps fluid...

No worries, glad to help. Apparently our pumps use Mercon ATF. If I replace the pump that is what I am using to minimize the whine, along with a good burping before I ever get it on the road. Yeah, not a drop on the floor since the Lucas went in. I used their oil additive as well and have slowed down the oil consumption a bit. I only used 1/2 a bottle and they recommend up to 40% in the crankcase if oil consumption is severe. I may need to add some more here shortly. Happy trails....

I wouldn't recommend you to change PS fluid by synthetic ATF.

Look, my PS pump was charged with ATF about 10 months ago...a few days ago, a leak started from the shaft bearings of the pump...so, I clean the pump of ATF and charged it with PS fluid...the leak gone.

The PS fluid have a higher density than ATF when they are hot, by this reason, pump is less prone to leakages.

When refilling the pump, you must be sure that fluid is free of air in all system of steering.
