I've been having an issue with the power steering for some time now, and it's time to deal with it. It works great cold, but once warm, I loose power steering while parked. As soon as you start moving, it works ok. I tried a new pump and I believe 2 new hoses, but nothing changed. I also did some sort of mod to the pressure valve or something I found on the moparman website. What's next? Steering box? I read somewhere about a hose that can collapse?
