Power Steering is Whining
Hi all, my power steering on my 1980 F-150 4x4 with a 351M is whining badly, especially when i turn. At an idle, it whines a little bit but when i turn the wheel aroound corners and sitting in parking lots, its extremily loud. I know that i can buy some lucas oil power steering less whine but i dont want to just put it aside, I WANT TO FIX IT, and this leads me and my dad to the question, is the steering box the one that whines, or is it the power steering pump, if yall can, I wil need an answer on which one of these it is and i know this has to happen on some of the ol' fords on this forum. I posted this in the right forum on steering, but its only gotten 1 view in 2 hrs, so if you could, i need the answer quick b/c were heading to Walmart to get the 4 wheeler tires put on and its right by autozone. Thanks in advance.

NApa as well as other retailer can get a Saginaw pump conversion . And they don't squeal . You may have problem being a 351 M Guy in finding one. I get mine from E-vans Ford put them on some of the vans. I put whole serpentine system off 94 on a 86 while back .
But I dont know if the older 351m vans have them or could be had.

All Fords do it, even the cars. You can try to get rid of it, but they all whine a little bit. Just make sure your suction line is not leaking, or it can suck air and make it whine worse that it normally does.

I tried the lucas, No good for me. Got a new pump, installed an inline filter and nice and quiet now.

before deeming your pump dying, make sure your fluid is full and isn't all full of air.
Check the fluid level, if it's low add some. If it isn't low, take the reservoir cap off and start the truck. If the fluid looks pink and foamy it has air in it.
If there's air cycle your steering wheel lock to lock a couple of times while the truck is running, but not moving. The whining should start to get better. It will probably never go completely away if your truck has the Ford C-II pump (plastic bodied pump).

Hammering on the shaft can damage the pump. If it leaks or is worse than the old one, then you know what did it. How did you get the pulley off the old pump? You should have had a special tool, which also installs it too.

the best way that i have found to put the pulley on is to find a bolt that will screw in the end of the shaft but before u screw the bolt in thread a nut up the bolt about half way then slide a washer on the bolt screw the bolt in and tighten down the nut with one wrench and hold the head of the bolt with another wrench. When u tighten down the nut the pulley will slide right on. When doing something like that u want a steady even pressure when putting them on. Thats one of the best ways i have found alot of time when u hammer on the pulley u can damage the pump pretty easy.

Your dad says you are dumb? Well then, you came by it naturally, unfortunately. 
You cant hammer the pulley onto the pump. It has to go on straight, or it will wobble.
Get yourself a Chilton or Haynes manual for your truck. They explain alot.
Your auto parts store probably has a very well-worn pulley removal/installation tool. They should have shown you how it worked before you left the store.
Best of luck with your truck.
