Hydraulic Power Assist Steering System problems of the 1997 Chevrolet 1500

1997 Chevrolet 1500 extended cab pickup 2wd when turning slightly towards the right the power assist boost increases causing the truck to quickly turn towards the right. I have noticed for many years and haven't known who to report this to. It happens quickly and I have to grab the steering wheel to keep the truck under control. I noticed the recall notice on the 1996 and 1997 cars but have had this identical over assist problem on my truck.

While driving steering will become inoperable when trying to make a right turn. Contacted dealer, and dealer was not willing to do anything.
