power steering issue help pls

[what a mess]

ok guys my truck was down for 6 months and about 3 months ago I started it up tried some things and at that time I had power steering and now I have none so I jacked the truck up both front tires off the ground and I can move the tires freely with my hands so then I check the steering wheel it moves freely also so then I started the truck tires off the ground still power steering works fine then I put a little pressure on the tires and it still worked fine but when I put it all the way down it works a little in the strait and barely turned but when trying to turn in all the way either way it get very very hard to turn and it seems like it gets worse the more I try to turn it back and forth and help would be awesome because it will get expensive throwing money at these parts any ideas advise would be awesome thank you

What size tires? Does it work ok when driving at speeds above say 10mph?

 

[what a mess]

33s and it doesn't work at all even at higher seeds

It got fluid in it? Hoses are pretty common to leak. If it is full try revving it to 3000 rpm and see if it works when sitting in park. If it does, its the pump, if not there is more we'll have to look at.

ok thank u and the pump is full

All I can think of is you have a clogged or collapsed line . Can you see the fluid circulating in the reservoir ? Is it whining when you turn the wheel like it is being forced ? If it was a newer box I'd almost say someone tried to adjust it and went to far .

 

[what a mess]

it whines a little but not all the time its the original steering box but trucks only got 120k on it nothing was done to the front end except wheel bearing but after they where done it had power steering would a like collapse just sitting?

I have seen all kinds of things happen from a truck sitting a while . Take one end of each off and see if its getting fluid , returning fluid .

ok will do I thank you much for the advise do you think it could be my hydroboost

I doubt it would be the hydroboost unless its leaking, which you said the reservoir is full. More than limely its the pump. Did revving it to 3000 fix it?

 

[what a mess]

it was the pump I also replaced the 1 power steering line that I hadn't replaced and I found some metal shavings where the like do line went to the gearbox so we put a filter in the system so that I can check and clean it

 

[what a mess]

and yes revving it helped make the power steering work
