Hello. Describing noises are always difficult. In any case, I would take a close look at the steering pump. In a "lock to lock" situation like you describe your engine (most manufacturers) should rev up slightly to compensate for the extra strain on your power steering pump. If this does not happen, have your mechanic check this. However, what's puzzling is that in your situation the steering shouldn't feel loose, but just the opposite. Are you loosing any fluid? Did someone perhaps refill the fluid with the incorrect type of fluid? Some steering racks are very sensative to the types of fluids take and putting the wrong fluid in can actually damage the system.
If you have an IFS vehicle I would also check into the condition of your half-shafts. A bad CV joint can cause a growl or click in sharp turns. Generally they don't go bad as long as they have lubrication, but I've seen them go bad and still have a good boot. Still, this CV joint problem should not create the steering problem you describe. Hope this helps.
