Hello I have a 92 ford f150 5.0 v8 and I recently lost the power steering and its only slightly turning to the left but nothin else no more and it's whining louder then the engine and bogging it down I don't know whats binding because I put In a junkyard gear box but I don't know what it is can somone help me please

 

Is the steering system full?

 

yes it's filled it does suck it down but I top it off there's no leaking either

 

It is full with the engine off? Air bubbles in the fluid?

What do you mean by “it’s only slightly turning to the left but else no more?”

 

You just put in a junkyard gear box and the system is full? I'd wager it needs to be burped. Put the front end up in the air (tires off ground), take the PS cap off and run the steering wheel lock-to-lock about twenty times or so.

 

I'll try that and engine off right

 

like it turnt but not far and I go to steer right and it doesn’t it stops and the tire is straight

 

After replacing the steering gear did you bleed the system or not?

Did you make sure the steering gear was centered before installing the pitman arm?

 

the pitman arm was already on

 

So you made sure the box was centered before installing the steering linkage? Your wheels were also straight?

 

yes I did but when I turn it it has alot of play like 2 turns worth of play which is so odd to me

 

2 turns of play? Junkyard gear? Go get another one!
Ouch
The roll pin in the control valve (inside the steering gear) is sheared
Tear into it
You are smart enough to overhaul a steering gear

 

20 turns lock to lock with the front wheels elevated is how you bleed the air out of a PS system
Go slow
