I have a 2011 S60 D3. I'm getting a lot of vibration through the steering wheel, especially between 60 - 70 mph. Vibration seems to be worse when going down hill.
I have had the tyres checked and the wheels balanced three times, but no improvement.
Any ideas as to a possible cause?

 

Try rotating the tires - swap the rear tires with the front to see if that changes anything.

 

Agree with hoonk, check tires first.

 

Anyone have any updates on this issue?
