V90 202 model
 

I have a recurring of vibration through the body of the car. I changed all of the wheels and tyres - i.e. swapped them all around and the issue seemed to settle and disappear. It has 34,000 miles and has had the tyres changed once. They are all Michelin and original Volvo spec. The vibration is back and begins around 55mph all the way through to 70+ It's just through the steering wheel, but through the body of the car making everything shake. Any ideas?
