Default Power Steering issues- feel and lack of assistance

Hi all. When driving my car it feels like I'm not getting as much assistance as I probably should (slightly heavy steering) and it doesn't operate smoothly. It feels like there is some pulsing feedback when turning, even a little. I have swapped out my power steering rack twice over the years. The rebuilding of the rack didn't think it was his part the 2nd time since they are pretty simple.

I'm pretty sure that my car is equipped with a power steering cooler if that helps.

I am trying to remember back if I switched out the p/s pump years ago. I think I did, but I can't quite remember and may have to visit the local napa or autozone to see if they have it in their system. Would what I'm describing above be more of a pump issue or perhaps an air bubble in the line? I have put probably a few thousand miles on since last swapping out the rack so I wouldn't totally think this was the case, but who knows. Anyhow, what are likely causes of my issues with my power steering?

No issue with air bubbles the PS pump purges air in the system automatically.
The pump may whine for a day until all air is purged. If it continues to make noise it is faulty.

You may have the wrong pump the size of the orifice in the pump determines operating pressure. Had this link saved it will give you an idea of what you need HOWEVER this valve is a change for LESS pump pressure.

If you have the sport rack they do steer heavier than the standard rack. Also if 9.5 front wheels they steer a bit heavier than later C4's with narrower front wheels.

Excessive caster adjustment = heavier steering.

Good luck
