Can you be a little clearer with your answer, are you saying that you believe it will be the power steering box and what would make the return very hot? I'm not sure if our line would get very hot if we were to drive it for awhile instead of just idling it for 15 - 20 minutes.
So then your saying it is probably the power steering box, and not a faulty aftermarket pump?
Thank you very much for the help, it is appreciated. I will order a new power steering box in.
