BTW my PS pump is brand new now, it wasn't the problem. I noticed after driving for 15-20 miles the other day that the steering did feel better and I was getting less bubbles. I then tore the system down and installed a new pump, which got me back to the point where I have quiet a few bubbles and the power assist pulses. Hopefully this works out, or this will be the 4th time I've had my car aligned since November.
You hit it on the money there... its an A1 Cardone unit
It would be so much nicer if I could just get a reman FE2 Rack from GM, in one big piece...
I believe it took about a week for me to finally have the power steering totally back to normal... I couldn't believe how long it took to bleed out the air bubbles.. I have yet to replace my power steering pump at 138,000 miles, but its been seeping from the front seal and has an odd high pitched whine...
And alignments... Grrrr... I need to replace my front strut mount bearings, while I'm there I should do the ball joints and the lower controll arm bushings.. Then yet another alignment..
