My power steerin pump makes a whining noise, It is the second reman pump Ive put on both of them whined real bad, any suggestions? Its on a 92 f-150 with a 4.9L Its driving me crazy.

 

Power steering pumps whine when dirt goes through them. I bet like everyone else (me included) you just changed the pump out and didn't flush all the dirt out of the power steering system in its entirety. If you don't do that, well, the dirt keeps circulating around and around eating pumps.

Just means something flaked apart before you replaced the pump in the first place, probably the first pump.

 

Most power steering pumps on Ford's do that whining. I wouldn't worry too much about it. My dad has about 7 trucks at work and most of the do that pump whining.

Well, ya they do whine a little bit, but usually you can only hear it when your in a parking lot going slow and turning tight. My friend's truck does it too but it's really loud, I can hear ir down the street.

 

The last pump I put on , I replaced the steering gearbox too, thinking that might have been the problem, I also flushed all the lines out. It whines very loudly do you think a brand new ford pump will solve this?

 

it's a ford, everything i own whines LOL, its just the way it is

 

Join the club. 94 150XL 4.9 and 81 F100 4.9 both wail like the old lady 2 days before payday w/ no cash.

 

Yep - my F150, my Mustang, and my wife's Sable ALL whine. It's a ford thing.

You guys could try changing/flushing your power steering fluid. It's not hard, just a little messy. I did it by first taking off the belt, then the return line at the back of the p/s pump. Be ready cause fluid will come out of the pump where you pulled the line off. Now hook a hose to the return line and into something to catch the old fluid. Turn the pulley by hand to flush the system out. Make sure you keep enough fluid in the reservoir, and I turned the wheels to different positions while flushing (if you jack the front end up it's a lot easier on everything). Run enough through so clean fluid comes out, then put everything back together. I used a power steering filter from Napa on the return line. Make sure the fluid level is correct, then start the truck and check for leaks.

BTW, my trucks call for Type F ATF. I've heard people say using "power steering fluid" made theirs noisier. I don't know if that's true or not, but I'm sticking with the recommended fluid.

 

I just put a reman on my '92 f150. It wines worse than the old leaking one. Unfortunately, never thought of flushing the system. But it does kind of blend in with the rest of the noises. I'll try to do that one day, 'til then, I just turn the radio up.

 

Try some Lucas power steering conditioner.

 

When I bought my used '92 F150, the power steering pump was screaming. I guess I got lucky, cause I replaced it with a reman Carquest and it has been pretty quiet for over a year. Like some others, I did flush the whole system by disconnecting the return line off the gear and into a catch basin. With keeping the resevoir full of clean fluid, I ran the pump and turned the wheels back and forth to flush the steering gear until I got clean fluid out of the return line. I got quite a bit of nasty fluid and crap out of the gear before it ran clean. Believe this has helped keep my new power steering pump quiet. Charles

 

I just put a new peice of reubber hose in my return line but filled it with power steering fluid is this bad, should i flush it out????
