I'm wondering if anyone else experiences the same feeling when driving over bumps at highway speeds. My 07 3.2 seems to be loosing traction and it seems like the car is airborn and shifting a bit when crossing bumps across the line at about 70 mph. Weard feeling, almost like the car is airborne. Any help will be appreciated. The car has 44K on speedo. I'm a second hand owner and as far as know no suspencion parts were changed.
