Having trouble turning left. Have replaced Power Pump already. Right turning is good. What part should I be looking for? Power Steering Gear? Next:I unplugged the Steering Column bottom adapter and reinstalled..Did not work. ALso, did put vehicle on jacks but no difference. When the car is stationary and engine on, I turn left and the car starts whinning and stiffen up..Infact, sometimes it locks up. When I am stationary and engine on, I can turn left easier when I push in the Gas in and it actually helps move the Steering wheel. Can it be the Power Steering Gear Box? How about the Hydro Booster system?
