Put it up on jackstands, fire up the engine and keep it at 1500 RPM or so and cycle the steering from lock to lock. The escaping air might push out some fluid but that's okay. Stop the engine, add a bit more fluid, and repeat.

Then check the fluid level while it is running and top it off to the full level.

Hope the bleeding air out takes care of it. There are instances where they won't work properly at low rpm's. Didn't mention if steering box was new or used. If used, a good flushing wouldn't hurt.

Wasn't there instructions with it ? You NEVER EVER run the engine while bleeding the system. Thats how new parts can get damaged. You want your fluid (calm) while bleeding the system.

Disagree.

You NEVER EVER run the PS pump without first filling up the system. The term "bleeding" assumes it HAS fluid.

It was a used unit. Replaced the pump a while back. Its noisy now and having a hard time at low idle. Maybe I will flush it out and start over. If not. I will get another gear box since it was quiet before I started

YOU DONT HAVE TO FLUSH IF YOU DONT WANT TO.. TURNING THE WHEEL WONT MAKE IT FILL ANY SOONER EITHER. THE BEST THING IS TO FILL TO THE BOTTOM OF THE TUBE AND LET IDLE, AIR WILL COME TO THE TOP AND IT WILL SOON FILL.. JUST BE PATIENT....

Removing the tires before firing up the engine will give a more complete bleed as it will allow the steering to go max side to side

For whats its worth I had the same problem with mine. I had replaced my pump with a reman and at idle or coming in to a tight curve or stop sign I had no power steering. I could pop the hood and watch the return hose jump when i revved up the engine. I tried all the ideas of bleeding the system and come to find out I just had a bad pump.
