The kit came with a rebuilt steering box and pump from a '68 thru '76 truck. Everything runs OK, but it makes lots of noise, sort of like when you turn the wheel on a power steering on a car all the way in one direction and hold it there. The noise is only when you turn the wheel, even slightly, then it really squeals. The belt is not slipping. Questions:
1. Anyone had this happen before
2. I think only the pump could make this noise, correct ?
3. Any suggestions.

Maybe something is causing too much pressure.

Check your fluid level. If you did not bleed it prior to checking fluid, when you turned the wheel, it moved the servo off center and started filling the rest of the sytem. If that is the case, then you simply need to add more fluid. however you could have a bad pump as well.

But....I did not bleed it before I filled the pump, since I did not think I had to since it has a low pressure return line to the pump. OK - I screwed up, but the pump is filled all the way (I overfilled thinking that it was a low fluid problem). How do I bleed this thing now ? Can I just drive it and it will eventually work the air out itself ? It makes no noise when you are not turning the wheel in one direction or the other.
Thanks for the responses. | | | | | Joined: Apr 2005 Posts: 2,097 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 2,097 | The recommended way to bleed the systen is to jack up the vehicle with both wheels off of the ground. With the engine shut off, turn the wheel lock to lock about 20 or more times. Check the fluid and fill then start it up and check the operation. It should be OK.

If the noise stopped, then you have the air out.
BTW, the fastest way to kill a PS pump is to run it low on fluid. Cavitation kills.
