Hello, I’m now driving my second V50 (2.0D – EZ 12/2009). Now, after changing from winter to summer bikes, I noticed that the right rear wheel gives a clear singing of itself. I already had the same problem with the predecessor – also at the back right. As I assume that this is about saw tooth formation, I am surprised that problem occurs back right again. Now my question: Is this a general problem of the 50s? Is there a way to avoid this! In advance, thank you for your answers.
