Power steering problems

I'm having issues with my power steering, I've got the front on jack stands. I start the engine and barely turn the wheel to the left and it slams to the left. I have to really pull on the wheel to get it to turn to the right then it gradually goes, but no longer do I get it all the way to the right, it slams back to the left.
I have looked at other post with similar issues, however no one ever says what they did to resolve the issue.

As always, I thank you for your help

 

have you had it apart?

 

depemds on what you mean on "have you had it apart."
I removed it from a 1974 Maverick, and installed it on the 70 Maverick...
yes the system has been apart, not the components

 

are you positive the cylinder hosed aren't reversed???

 

No I'm not, but the lines are not crossed

 

Krazy Comet, I saw in a post you were going to use a vacuum pump to get the air out. Did you ever do that and did it work?

 

Good chance hoses are reversed. Usually if they are reversed the wheel will slam back and forth uncontrollably. Try switching them, start it up and be ready to shut it down. When the hoses are right, turning the full left to right a few times should work any trapped air out.

 

i did that on my build, and that was the problem and solution.

 

I read the service manual and nothing was said other than fill and cycle the steering a few times, then recheck level... So that's what I did and works fine... The way the lines connections are orientated it's easy to get them connected wrong and hookup looks fine...

 

This happened to me once. Connected the lines and started it up. Thought everything was fine until I started to turn the wheel. It slammed to one side and stayed there. Turned out that I had the hoses reversed. I ended up havin gto have the steering rack rebuilt because it blew out the seals when I did that.

 

OK, 4 guys that had the same problem. I will reverse the lines and see what happens. Does it matter which end I reverse/swap?

 

When we say the lines are reversed, we mean you have the high pressure line routing to the low pressure side of the steering box. Just swap the lines at the steering box.

 

No I mean the lines to power cylinder are reversed, while it's possible, reversing the lines to valve from pump isn't likely(at least without cutting)

Makes no difference which end is swapped at valve/cylinder...

 

I will get on it tonight guys, thanks for your help. I will let you know of the outcome.
