Air bubbles in p.s. pump

I just recently installed a new steering box and a new p.s. line to my existing pump. Now I have air bubbles in the pump. All I did was fill the pump up and started the car to work fluid into box, shut car and re-filled and started until steering started to work.Never ever had bubbles before this mess.Did I do something wrong?Is ther a way to do this properly or am I ***** out of luck and have to deal w/bubbs.?Plus now it makes that crappy big car steering sound like a caddy or delta.That humm sound.
Do I have to drain and re-fill???

The bubbles will go away (or they should). I will lift the front tires off the ground and turn the steering wheel from lock to lock with the engine off to bleed out the air trapped in the P/S system. If you drive it around the bubbles should go away and the noise also. Good luck.

basic problem in fords......fix is
turn wheel (almost) to lock & hold for 3-5 seconds. Repeat process other direction. Do this 2-4 times, should clear the problem up. Do not hold the wheel all the way to the stop.....this will make the pump angry

Yup, when I replaced a pump before I didn't even bleed the system, it was like manual steering to get it out of the driveway at first. After about 2 trips into town and back, it acted normal. If the whining doesn't go away, make sure you have the correct fluid in it. Some take ATF and some take power steering fluid. It doesn't hurt it if you put the wrong fluid in, just change it soon. Mine whined like an old ford pickup steering until I put ATF in it.

Cool. Thanks everybody for replies.I will go and test drive it now. I thought I screwed it up somehow. At first I couldn't even turn the wheel,- felt like the tires were glued.Then it got looser as I added more fluid.It was the sound of air release when I shut the car off that worried me.

disagree with ATF. It will ruin a Ford or Chrysler pump pronto.
use STP or Lucas. Especially if it is a Ford pump.

Had PS fluid in my chrysler pump for about 2 months before someone told me it needs ATF. I flushed/changed the old fluid out and it hasn't whined or blinked since, and it doesn't leak either. It has to push around 36" tires too...

My gosh, I didnt realize we were using ps pumps from the dinosaur days, I thought they were at least the '80 types..... which use clear fluid.
