well, BMW of Fremont was finally able to find root cause of vibration on my M5.

Apparently, my right front bushing was pushed way too in hence my control arm does not have enough movement. That is causing my right front to vibrate.

So a new control arm has to be ordered. Then the wheels/tires has to be rebalanced and alignment has to be done.

Bad thing is that there is no part and don't know when new parts will arrive.

Good thing is that I can at least still drive it. Just not speed too much.
