I have an 04.5 that recently sprung a power steering leak from the pump and line. During this I did not let it get too low, however during the trip It started getting really noisy. I replaced both with the new style cardone brand. Steering was difficult and noisy even after hours of bleeding the system. I spent a lot of time vacuum bleeding as well. I then put in a OEM 2010 style pump with the same issue. I then put in an OEM steering box and have the same issues. It is almost impossible to turn the wheels when parked. It gets tougher if brakes are depressed. It gets very noisy when turning at 1500 to 2000 rpm. It currently wanders around which it never did prior to this. All other front end components are only a year old and are the 2009 updated with dynatrac ball joints as well. Everything is tight and nothing binds when turning wheels while lifted off ground. Could there be a blockage somewhere I am not noticing? It gets much worse when I load up the truck camper as well. Everything worked perfectly prior to this incident.
Another strange thing is when I am vacuum bleeding, as soon as i get to 20in-hg it starts getting very noisy as if there is serious cavitation. Maybe normal? Could there be a something in the hydroboost? Brakes work great.
