Brake dust!
During hard braking, inertia would cause the weight of the vehicle to shift forward towards the front wheels. This is because the momentum of the vehicle is being slowed down, leading to a weight transfer from the rear wheels to the front wheels.
Front end wobble at high speeds in a vehicle can be caused by issues such as unbalanced tires, worn suspension components, misaligned wheels, or steering system problems. These issues can lead to instability in the front end of the vehicle, resulting in wobbling or shaking at high speeds.
Wheels require balancing.
The jack points on a 1998 Corvette are along the vehicle's frame, just behind the front wheels and in front of the rear wheels. They provide a secure point to jack the vehicle up.
Should be on frame behind front wheels (side of vehicle)
Only the front or rear wheels drive the vehicle and not both.
What year and make vehicle?.
Over-steer is the handling of an automotive vehicle that causes turns that are sharper than the driver intends because the rear wheels slide to the outside of the turn before the front wheels lose traction.
more than likely a bad wheel speed sensor
Yes the front two wheels propel the vehicle.
Ussually it's the ball joints and it's ussually only on one side of the vehicle. Most noticable when turning the wheels.
Normally if the front wheels are misaligned at the front, either leaning in or out at the top, this suggests that the camber is out of alignment. The recommendation here is to take the vehicle to a wheel alignment centre and ask them to check it for you.
