Ok, who feels stupid????? That would be me.
I changed the fluid as stated, no change, however, I wished I had asked someone to move the steering more while I was able to be under it. I finally got frustrated and called the local repair shop, they suggested a full flush before replacing the pump, so got an appointment for this afternoon. Something just kept nagging me, so I researched a little more. Found a post on another site, (one that a lot of us originally came from), from 2010. This guy had a video recording. Same damn sound. He said it turned out to be his ball joints. I have replaced my ball joints. Humm, wonder if the local Ford guys have ever looked at them when they serviced my truck.........
A little grease in all the zirks, wow, no more sound.
Note to self, do them yourself.....
Still wierd that it all started when our temps went below 0 and stayed a while.
