2001 Chevy Tahoe V8 Four Wheel Drive Automatic 144000 miles
When idling and the vehicle not moving - attempt to turn the steering wheel and it is very difficult to turn. Also the power steering whines and sounds like when you have the steering wheel turned all the way in one direction. I feel like I am fighting the power steering and then all of a sudden it will turn or if I give it a little gas it will turn. Does not happen all the time. When I jack the Tahoe up the steering turns very freely. I have replaced the power steering pump and that did not fix the problem. Replaced the rack and pinion, that did not fix the problem, replaced the power steering pump a second time and that did not fix the problem. After each replacement I purged all the old fluid and put in new. Bled the fluid each time. Still the same problem. Does not have hydro boost, does not have magna pure filter, has one pressure line and one return line. Has variable resistance steering. I have tried disconnecting the electrical connector and at low speeds makes no difference. Computer reads no codes of any kind. None of the lines are plugged or make a tight turn. Replacement pump I was told is rebuild Cardone 20-8748. I can not find any vaccum booster or connector to the pump, gear box or brake vaccum unit. Any ideas?
