Well I had my engine replaced today and just like you Ninja, I notice a slight improvement but not a huge difference. Vibration is still there particularly at idle, but it's almost all in the steering wheel.

I noticed holdign the steering wheel by the controls (volume and phone buttons) you feel it much worse so now i'm just gonna keep my hands at 2 and 10 o clock - barely feel it there. So yeah, not much of a solution but instead a 'compromise'.

It does seem to be smoother when moving - less vibes at 1200 rpm which is where it was worse before. Still there but less.

During all this, I did go and test a few cars of same age and mileage and they all vibrated the same so I'm ready to give up and accept that maybe this is just the way these cars are...
