My ISF has about 8000 miles on the clock and I have noticed what I can only describe as a hollow sound when going over small potholes or uneven parts of the road. It does not happen over every bump and does not come from all four sides of the car.
I know the ISF has a fairly stiff ride....but....their is no noise from the other wheels/suspension......anybody else?????
So on the way home from work I tried really hard to pin point the sound...got it...hollow...I really cannot think of any other way to describe it...Try going over a bump...do you hear anything except for road noise?
