My car appears to show the symptoms of the worn CA bushings. I had it into the nearest Lex dealer 2 weeks ago for an Oil change and tire rotation. I asked them to check the upper bushings while they had the wheels off and the car was on the lift. The tech reported that he did not see any wear, In reading these posts it appears that the lowers could be shot but they are not visible. Is that true?

I bought the car from a Toyota dealer, it came wit a 2 year certified warranty, the only problem is that the Toyota dealer is almost an hour away. Before I take it any advise as to how I should approach it. I do not want to spend my day there just to be told they could not find an issue.
