All:
Let's not lose sight of one thing, all I *expected* was a return communication, maybe indicating a "local" dealer with experience with the problem who could accurately diagnose and get it fixed or provide guidance as to what parts I need to fix it.
I am MOST disappointed that KTC has refused to acknowledge my communication with them, no reply AT ALL. I did not at the time of my message to them and definately do not now, expect KTC to "do anything" about the problem. Their failure, or as I see it, refusal to acknowledge my complaint is not only poor business but discourteous.
As I indicated earlier, I am not interested in naming those dealers that have been less than helpful, primarily because that will not accomplish anything useful.
fiddler:
This is a problem that occurs when the fluid is warmed up to hot and at low engine speeds. There is no "power" in power steering when this happens. It does not take much running to duplicate the problem, the hotter the fluid gets the higher the engine speeds need to be to keep the power steering working.
I am estimating a little, but with "room temp" fluid and the engine at idle everything is fine, with fluid at about 120*F the engine needs to be off idle a little and by 130*F (too hot to touch for any length of time) you need 1400 rpm or more or there is no power steering at all and the steering "bucks" as you turn the wheel.
Every other hydraulic system works fine regardless of temperature.
