I have a 98 Z24, about 180,000 kms on the car. the car was just safety inspected by a reputable shop, so it was a thorough inspection, not just a 5 minute walk around. My problem is this. When I get the car to 100 kph the front end starts to shake. You can feel it through the steering wheel and it is noticeable through the whole car. So if the front end, tires, suspension all passed inspection, up on the lift where everything can be checked what's going on? Tires have about 25,000 kms on them, always rotated & balanced. Other than that it works like a dream...any guesses?

my driveaxles did that before , just something to check out , wheel out of balance , broken belt in tire and maybe its out of alignment.
