H2 unit bearing WTF!?!?!

[Nuts]

The girlfriend bought an '06 H2 with a 3 year warrenty about a month ago. Saturday morning I drove it and heard a loud sqealling from the drivers front wheel. She'd been telling me about it for weeks but thats the first time I heard it. So I went back home, jacked it up and just as I had thought the unit bearing/wheel bearing was SHOT! I could move the top and bottom of the tire in and out about 3 inches. Instead of me fixing it and killing her warrenty we took it back to the dealer so they could do it. She called this morning to check on it and they said NOTHING was wrong with it at all... Long story short, I went there and after a talk with the service manager the Xeina police were nice enough to show me the door. But before they got there I was aloud in the shop to "see for myself" and found absolutly NOTHING wrong with the bearing! It spun smooth and quiet and was as tight as a new one. So how the hell can this be possible!? I know a bad bearing when I see one and Saturday it looked like the wheel could fall off at any second, but today it was like new and they swear they didn't work on it...
