2014 E550 4MATIC - Vibration Issue
Car is in shop with tech. But they still couldn't find whats causing this issue.
Tech has checked, Engine mount, tranny mount, LSD, tires and alignment. All these are working fine, no issue.
Here is the symptoms.
It vibrates more as speed goes up.
It still vibrates when going slow, but not very obvious.
It usually happens when car start torquing up.
Car drives powerful, no power loss.
And I test drove it in circles.
When going right in circles, I heard something is knocking constantly.
Its like wheel/tire rubbing on the ground unevenly.
When going left in circles, no issue.
Here is the weirdest part !!!!
The vibration will be gone after i straighten steering wheel from going right direction for a short while.
But vibration will come back shortly after speed going up about 70kph.
I really have no clue whats causing it.
I believe is something small. but need to locate the issue.

My 2 cents .. hope it is as simple as that for a fix
