when turning left or right, after straitening the wheel, it will jerk uncontrollably left and right. i have to stop and then i can proceed. changed hydroboost-no help, changed steering gear box-no help, changed power steering pump-no help, changed power steering lines-no help. the truck continues to do this. also-now have a whine after changing power steering pump that was not there before.
