Left for work 4/20/12 and got about 2 blocks before hearing something make a noise that sounded like a pop. Can feel the bike dog tracking and the belt is squealing so head back to the house at about 10 mph. Take it apart today 4/22 and sure enough the right side bearing is toast and has already damaged the bearing spacer. The axel and swingarm were undamaged so lucky i was so close to home. By the way its a 09 Uly with 16483 miles. I used to think some people were going overboard with changing the bearings every tire change but now i wonder.
