Noise when turning on 2004 Volvo S80

when turning the steering wheel, particularly slow - like backing up or going forward turning (it does not happen on the fwy) there is a grinding noise. This started at 30K and still continues at 103K. I have had it in several shops, no one can find the problem. I have had the front upper struts and mounts replaced. I have been told they greased the steering shaft. I have had it to three volvo dealers and three private shops. My car does not seem to be one the list for recall control arm bushings. where can I go to get someone to really locate the problem? I love my car but also hate it too. My dream car is no longer a dream. I wish I could trade it off it but someone else would have to deal with the same issue and that is not fair.

Since front upper strut mounts have been replaced and you say the steering shaft has been greased, has anyone of the shops ever said anything about the p/s pump or rack and pinion assembly? I would be surprised that they did not say anything to you about that. If vehicle can be put on a drive on rack with the weight on the tires and turn the wheels while listening with mechanics ears you would think the noise could be duplicated and pinpointed.

Does it sound like a low power steering noise, while you turn the steering wheel it growls or groans?, if so check the power steering fluid level, if it's full sometimes if you look carefully in the reservoir you might see a little metal sleeve sticking out of the return hose (upper hose), if you do see that then the reservoir is causing the power steering air cavitation thus the growling noise.
