Ok so this has been discussed many times however I want to have an engineering look at it. My Tesla S 2016 P90D pre lift had the shrudder thing, basically driveshafts were broken, fine. So what I have done is I replaced them both, also checked the center bearing for the right half shaft and its fine, replaced the small engine mount to the new revision. The shrudder is gone as expected, but the vibration on hard acceleration is not! So I looked under the hood and recorded whats happening inside during hard acceleration to have some insight. From what it looks it might be that the engine is moving possibly too freely. There is this other engine mount with multiple bushings. Can it be that its design is also flawed? Or maybe its broken, hard to see the bushings without removing the engine. Have a look at the video and let me know your thoughts.
