I have rebuilt the steering box and adjusted it to specs.
Aligned front end.
Changed power steering fluid with MB synthetic fluid.
Replaced filter.
Replaced struts and strut bushings.
Replaced tires.
The power assist works great even at idle and sitting still. Everything feels smooth and easy when up on jacks.
I have been searching these forums and have found no similar problems. I would greatly appreciate any info to lead me in the right direction.
Thanks

Are you sure the pump is pumping?
Could be the shuttle valve in the steering box.
Have you checked the condition of the steering damper - a few years back people used to report this as a problem part (but as with many things this seems to have gone out of fashion at the moment).
Other than that consider the condition of each part of the front suspension and steering - work through it all methodically.
