main bearing sound

[derric]

Took my 09 E90 M3 into the shop for the sound which sounds the same as many of the YouTube clips and what not. I was able to emulate the sound for one of the guys at the shop but not the one that reported that my sounds was not the same as the bearing sounds he had heard in the past and that he had worked on. Basically they told me the sound was normal which I have a really hard time believing...but not sure what I can really say...
