At low speeds my 2002 chevy 4wd will not turn to the right. Left does not seem to be affected. I have replaced the belt, and the belt tensioner, and the idler pully with no change to the steering. I also have replaced the power steering fluid on a regular basis (50,000 miles between). I was about to replace the power steering pump when I found that others have had problems with the rack and pinion. I am hoping this report will convince gm to issue a recall. Truck has approximately 107,000 miles.
