Okay, so that's Doug's term for my car's behavior.

But what I'm wondering is if anyone can help me out with a symptom.

While driving along, predominantly at @75mph, the car pitches its nose back and forth. In aviation we call this "yaw". In driving I call it nauseating. Anyway, I've had the car up in the air and looked at all the suspension components and can't find anything amiss. I have also checked differential fluids and all are normal. Also, also the struts seem fine. And lastly the sypmtoms come and go. Unfortunately they come more than go.

Anybody have something like this happen to their SVX? And yes, the tires are inflated properly. Even the spare has air

Any help is appreciated.
