Then I noticed the bearing in the front strut mount on the passenger side was broken when I removed the cap and saw the strut retaining screw was off center. So I replaced the strut mount and struts on both sides. The problem was still there. Then I inspected the steering rack coupler tightened it and marked it so I could see if it was moving. It was not moving and the problem was still there. I then raised the car and grabbed the wheels at the 3 and 9 o'clock positions and moved pushed and pulled and there was movement. I saw on a video somewhere this was a possible cause and an indicator of bad ball joints on the lower control arm. I replaced the control arms on both sides and the problem is gone. I hope this helps someone. It took me months and a lot of unnecessary repairs to find the cause.
