Today we tried shimming the power steering pump to reduce the pressure for better road feel. After reading several posts here and elsewhere, we agreed on a total of .125 thickness. I have read of some going as high as .140 with good results so I figured that .125 would be a good starting point. It turned out to be too much! Once rolling, the car steered fine but with the car sitting still, the steering wheel went about 1/3 of a turn then got too hard to turn without using both hands.
He plans to step back to .100 or so and reevaluate.
