Hi,

I drive a 2006 GV 2.0 with autotrans and 4WD.  The mileage is now at 10000 km and it is due for servicing.

I notice that 1 get vibrations (mild) whenever the car is between 80 to 90 kph, in both the 3rd and 4th gears.The vibrations appear when I accelerate between 80 to 90 kph.  However, they disappear when I lift off the pedal even at those speeds. 

I think it has to do with the engine/drivetrain setup and not wheel balance.  The vibrations do not appear before and after 80 to 90 kph.  The vibration pattern remains the same even after I rotated and balanced the tyres.

Anyone has the same experience or know why I get the vibrations?  I have never owned a 4WD before so do not know if the vibrations are normal.  As the car is due for servicing, am hoping to understand if there is a problem so that I can raise it with the workshop.

Grateful for any help anf thanks in advance!
