Well...Replaced the hydroboost on my truck cuz I thought that was my problem. I had power steering fluid pushing out around the cap on my power steering pump. The fluid doesn't seem to be pushing out anymore but my steering still whines when I turn and gets stiff every now and again. It has been a week so I would think it would be bleed off by now. What should I look at next? The pump itself? Also how many of you have put an aftermarket steering box on your truck and do you like it and is it a major improvment? I am going to be replacing my ball joints on both sides and I have a tie rod end that is pretty bad. I am going to see how my steering does after that and then I might put on a new box and a brace. Any information and suggestions would be greatly appreciated.
