Death wobble red XJ?

[TJDave]

Yesterday, I was driving the flatbed truck across the I-182 bridge heading back to the plant in Pasco. I was behind a red Cherowagon when all of a sudden, he started swerving all over and slowing down. I changed lanes and when his front end came in to view...HOLY CRAP!, full blown death wobble. I thought the whole front end was going to fall off. As I passed, the driver was fighting the wheel like Cousin Carl at Talladega. He did a great job getting it slowed down and back in control on the small amount of shoulder available on the bridge. I have never seen or experienced full blown death wobble, and after seeing that, I hope I never do.
I just wonder if he is on this forum, and might be in need of some good front end advise from the Pro's.
