I have had a rear one go on my gcv and a front one go already on my 09 Journey - wouldn't you know it, it was just off warranty (I believe it was the brakes overheating that transferred the heat to the bearing and cooked it as the Journey has the same problem as the Caravans with eating brakes). The funny thing is it sounded extremely loud and like you I thought I better get it changed quick before it disintegrated, but surprisingly it wasn't as bad as I had thought - it was quite rough though. Shouldn't be too hard to change. Good luck.
