Sounds like a strut or strut mount to me as well.
The problem I have with dealers around here, is that they won't let you take them on a test drive, and they won't let you ride during the test drive. It's no wonder they can never hear or replicate a problem.
It a tech/writer actually drove your car and couldn't hear that, they were either lying or didn't try to find the problem. IMO
