Power steering gear nightmare - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I put a different steering sector on my 72 K20, when I pulled up to the garage the power steering worked, but the sector leaked. The new one (junk yard) seems to work fine to the right with one slightly stiffer spot, but to the left the pump whines all the way to the stop. I have the front end up off the ground. I bled the system buy going stop to stop, ( probably 50 times by now), always keeping fluid in pump, I also cracked the return line a few times. I let the truck set for hours then tried it again, then over night and the same. I think I got another bad sector, what do you guys think? This is the third one from this yard and I didn't get one back in 90 days so I have $125 in this deal. The yard is over an hour away and I had to wait 4 weeks for the last one. If I ask for my money back I will only get $50. The guy is as sick of me is I am of him so I want to be sure it's the sector before I call back, so what do you guys think the problem is? ( I know now I should have went with a rebuilt but I am buried in this deal now)

Drill a small hole in the pS cap and go ahead and get a new cap as well to replace with. It sounds like air in the steering box coupled with prob. a little moisture in there as well- check the fliud and see if it is milky- the hole in the cap will serve as a bleed off for the box. Be prepared to make a small mess if there is some trapped air in the box, but the bleed off will get it out. Continue to do as you are will the lock to lock turning up on stands. Doing this with the "bleeder cap" in place should get rid of your problem. Hope this helps.

There is no water in the system, because I drained all the fluid out of the pump, and worked the gear back and forth and fluid came. I kept full with new fluid and went stop to stop. I thought the caps were vented, I could hear air when I first started bleeding, some fluid even came out of reservoir at first. I also have cracked the return line and went stop to stop many times. I have done everything with the wheels raised and already have the mess, there is oil everywhere and I am outside, please don't call the EPA.
