    OK, I have searched and searched...but not luck.
    '73 Blazer
    Crossover steering
    Dana60


    I put a new 2 wheel drive gear box on, turned it back and forth 100+ times but sitll no real power assist. I took the gear box back because I thought it was no good. I did the same thing (back and forth back and forth), but still no workie. If I have the wheels in the air, I can easily turn from lock to lock, but as soon as the wheels are on the ground, the pump starts squeeling after 1/4 turn. I replaced the PS belt and still the same thing...I can drive my truck but have very limited power assist. Also, the wheel does not return to center or come back at all when I turn to the right or left...

    Here is my question:
    - Is it possible that a new gear box somehow fried my PS pump or that a new gear box exceeds the output of an old warn down pump?

    - What causes the steering wheel to go back to the center when you let go?

    - Any other thoughts?

    sounds like your due for a new pump, im pretty sure the wheels try to center by themselves unless their is a force trying to turn the truck where they will follow

    could the box not be adjusted properly?

    The steering box? I put the hoses on correctly, filled everything with fluid, made sure it was bolted down nice and good..what other adjustments might I make?

    The adjustment screw on the top. If it is out of adjustment it could be slopy as all hell. is there play in it? If it is to tight it will lie the steeering over and not return(have no center)

    It sounds like you have a blockage somewhere though. There is pressure back feeding back into the pump. Are the lines going to the correct positions?

    Just a couple thoughts.

    The lines cannot get mixed up as they are different sizes. Sounds to me like he has a bad power steering pump. Regardless of if it worked before he did the crossover.

    Disconnect the pitman arm from the sector shaft and see if the problem goes away. If the geometry is real bad it can stop the pump. Is the new box the same year as the original? Did you swap the sector shaft? If so, how did you tension the adjuster nut?

    However, it is always a good idea to get a new pump when you replace the box.

    I helped Noah this weekend on his steering problem so I can answer some of these questions. No its not hydo assist and yes its a brand new 2wd box not just a sector shaft swap. We did disconnect the draglink from the pitman arm and it turned back and forth without any problems but I dont think the geometry is bad. We even double checked by centering the steering wheel and the tires one more time. What is happening is that when ever you try and turn it (parked in driveway), it stalls the pump and causes the belt the squeal. It will turn when driving but if you turn to hard or to fast it does the same thing. The only other thing I could think it would be other than needing a new pump would be that there might still be air in the system?

    mine would not turn at all on any surface unless you were rolling. I modified the pump the same way you would for hydro assist and that helped a lot. I had a new 2wd box and pump and had the same symptons as you. your tires are too big.

    Jimmy, the linky no workie...

    Pumps are relatively inexpensive so I will go that route as I do not know what else to do, it is an old pump so it could be that the new steering box put it under just enough strain that it gave up...

    Had the same exact thing happen to me. Put on a used 2WD box and tried to get it to bleed out. Found out that the box was not working and ended up ruining my pump. Once I got a different pump and a new steering box everything was fine.

    spend the $45 and get another pump so you can wheel sooner:wink1:.
    If you have an older pump, the higher demanding steering will wear it out in a week anyways :(
    BTW the pump mods burned my pump out in a few short days, neveragein will I do that :doah::mad:

    Where do you buy pumps for $45? Napa has them for 70 or 75?

    The magic pump that blows the end caps off of steering boxes:doah: :D .

    I have been running my factory pump that I modded for about 2 years now and the last 6 months was with hydro assist and I have not lost one yet. I would recommend a new pump as I did not have any problems with turning after crossover with a good pump.
