How do I bleed the power steering on my 90 jimmy?

[shaun]

I just replaced the stubshaft seal, oring, and dustshield now I dont have anypower steering. I have bleed the system according to the book. You just turn the truck on turn the wheel back and forth and pull the cap to release all the air. So I am guessing my pwr steering pump has failed. How can I tell. I have no p/s and no leaks. Is the only thing left the pump or what??? /forums/images/graemlins/1zhelp.gif

Haven't had to ever do it but I remember you turn it in reverse to get the air out.

I dont think it's the pump that pushes the fluid when you turn the wheel but rather the piston in the steering gear. In the past two weeks I have been modifying my pump for my MM hydraulic winch and completely drained and recharged the system several times. All I had to do was fill the reservoir and turn the wheel back and forth about 40 times. damn boring job but it works perfektly every time. Check you lines and try again. Have someone watch the reservoir to make sure the bubbles are all out.

No bubbles are coming out so I believe it is bleed all the way. Is it possible I put the stubshaft in wrong? Or is it not sittting in the valve rings correctly? I am confused. Today after work I will start again. What fun /forums/images/graemlins/histerical.gif
