I have a 2007 dodge 2500 5.7 hemi truck. I am having issues losing my power steer pumps. Original went out month ago. I put two endurance brand pumps refurbished in it. One didn't last 24hrs and the other three weeks. Then I put in a new oil cooler and gear box and new duralast pump. New pump went bad the next day. I replaced one of the pressure hoses as well. Now I bought an original used pump to see if that made a difference and now it's starting to whine two days later. Nobody can figure out why I am going to through pumps. Any thoughts? I'm Losing my mind. Thanks.
