Lucas makes a power steering conditioner that I've found works pretty good. My rack was leaking and had some dead spots ... put that stuff in and it all cleared up. Otherwise you're probably looking at a new rack or rebuild it.

Good luck

If you can SEE the hood rise at the ends of the turn, and drop as it comes across center, there is a lot of caster in the alignment. Some shops put a lot of caster in these cars in response to customer complaints of "wander". The result is a car that is not particularly pleasant to drive, although it tracks straight ahead. My personal experience is that 4 degrees is about the best compromise for 255/50's on 16" wheels. Other size tires may need more or less caster to get the best compromise bethween steering feel, and straight-line tracking.
The early c4s ran 3 degrees caster, that was changed to 6 degrees on later c4s before the 88-96 geometry changes.
I run 6 degrees caster on my 85, the steering is light no noticeable increased effort required.
Was a horror driving on uneven poorly maintained highways, the car would dart / wander dangerously.
The car has much improved stability requiring a light touch on steering wheel, compared to having to grip it tightly in case the car wanted to run off the road to follow a contour......
