Thanks Paul - when I took it to the dealer they told me the tie rod ends were fine. Perhaps it is something in the rear of the car. In any event it's going back to the shop tomorrow. Unfortunately my independent has given up. I love the car so much that's why I'm being so persistent. So we'll see what's next. My gut tells me it's still in the front end somewhere. I've been searching through posts and have found a few indentical conditions that others have, but no luck on the fix.
