NV7 Power steering pump whine/growl

Well, it's winter again, and once more, the growling from my power steering pump is VERY loud.

 

I've asked before about the noise, but wonder about a fix...

 

I'm aware that the '95 LQ1 Cutlasses got the pump, and it appears that both the pump and the variable orfice are not available any longer from GM...

 

Is the pump itself special, or is it just the variable orfice that makes it special...

 

In other words, can I use a standard 3.4 power steering pump, and just swap the actuator off of my existing pump onto the new one?

 

Or, do I need to find another NV7 pump?

 

Thanks!

I have put three new Power steering pumps in my car and they all whined. I currently have over 560 miles on my third one now and it still whines.

 

Do you still have power assist when turning? Especially at low speeds is it hard to turn?

Sometimes, when the temperatures are below 30, I don't have assist for the first second or so after startup when the wheel is first moved...but after that, it seems OK.

 

To be perfectly honest, if I hadn't read it is supposed to be variable assist, I'd have never realized it...feels about the same to me, no matter what.

Mine's pretty easy to steer, but I'm probably comparing it to the LeBaron convertible I had before. It had very heavy steering, almost as heavy as that old '64 Ford I used to drive. My Cutlass is about halfway between the effort the LeBaron had, and the steering effort of our HHR.

They are different... You can't use a standard pump on an NV7 car due to the way the lines connect... I tried it once... My Monte Carlos pump was standard and I tried hooking it up to my friends cutty which was NV7 and the lines wouldn't connect to the pump
